Wanting solid state drives (SSD - Solid State Drive) to be used for the past hour, I myself have recently begun to test them. The price was high, the capacity is small, although it was supported by a significantly larger swed code, equal to the sizable Winchesters. The first step is to delve into different types of SSDs, manufacturing technologies, vicory types of memory and controllers, follow the steps on the form factor (that is, in fact, physical dimensions) of these accumulators, that is how stench differs in shape, how roses can be connected їх vikoristati. Although a 2.5-inch form factor SSD does not call out the power supply (they are practically identical to hard disks), then another variety calls out the power supply. SSD M2 Let's get together
Development of the SATA interface
This interface has been replaced by PATA, having become compact, replacing a wide cable with a thinner and more compact one. Compactness exercise is a normal trend. Navіt for SATA znadobivsya raznovid, which allowed biyogo vikoristovuvat in mobile outbuildings, but there, de to rezmirіv komplektuchih vysuvayutsya especially vimogi. So the mSATA variant appeared - the same SATA, but in a compact package.
Whose roses have lived a short time, to that one for a change to get a quick delivery of another - M.2, which may have great opportunities. I would like to respect that there is no letter "SATA" in the abbreviation, but I did not say that the price is a new option for the same interface. Why would you understand a little bit of piznishche.
I'll just say that mSATA and M.2 allow you to do without loops, life cables, which increases efficiency, allows you to run a compact computer. Tim is bigger, M.2 is smaller, mSATA is lower.
How does it look like M.2 and why do you need it
This is a small rose, patching on the motherboard or expansion board, as it is installed in the PCI-Express slot. You can use M.2 not only for SSD, but also for installing Wi-fi, Bluetooth modules, etc. The scope of zastosuvannya can be even greater, so we can make M.2 work harder. If you are planning to upgrade your computer, then I care that the presence of a rose on the motherboard, so you do not plan to install anything in a new one, it may appear corrupted. Who knows what will happen in a few months, what new attachment you want to buy.
The stock M.2 can be seen in the illustrations. Vin can be like this
chi like that.
What's the difference? At the peremichtsі (called the "key"), yak є in nests. In order to understand this recognition, the trochs are buried in the computer interface.
M-key and B-key
Modern hard drives (including SSDs) are traditionally connected to the SATA bus. I have, ale briefly repeat here.
SATA III has a maximum throughput of 6 Gb / s, approximately 550-600 Mb / s. For high-quality hard drives, such speeds are unattainable, and the axis for SSD-disks will be increased richly, more speed, not to become a waste. Only there is no sense in it, but the interface still cannot be pumped over the flow of data with greater speed, as if it were a building itself.
That's why it was possible to win the PCI-Express bus, because there is a lot of bandwidth building:
- PCI Express 2.0 with two lanes (PCI-E 2.0 x2) provides a bandwidth of 8 Gb/s, or approximately 800 MB/s.
- PCI Express 3.0 with two lanes (PCI-E 3.0 x4) gives 32 Gb/s, which translates to approximately 3.2 GB/s.
Those, which interface is used for connecting extensions, determine the position of the key (jumper).
SATA (M+B key):
PCI-Express (M key):
SSD drives can have the following key options:
For example, take the ASUS Z170-P motherboard. It has an M.2 socket installed with an M-key. This means that the PCIe bus x4 is overridden. Just get power, but how can you install an SSD drive from a SATA interface? And the axis of the power chain is narrower than the cicava.
Be sure to check out the specifications of the motherboard and wonder if M.2 SATA won't. If you visit the site of the virobnik, then so. This means that an SSD drive, for example, an Intel 600p Series, is being bought, with a few assignments for the PCIe ×4 bus and there are no problems.
And what about, for example, the Crucial MX300, what does it work on the SATA bus? For the specifics of the virobnik, such an SSD can also be practiced.
Those that use the SATA bus in the M.2 interface should be given special consideration when purchasing a motherboard.
Summarizing what has been said.
- M.2 is simply a smaller form factor (size and variety) of SSD drives. The SATA bus and/or PCI-Express is broken. Retail M.2, which is installed on the motherboard, has a PCIe ×4 bus. The possibility of installing an SSD from a SATA interface may be specified in the specifications for the motherboard.
- Bus type SDD disk SATA drives sound like M+B keys, and PCIe x4 with M.
2242, 2260, 2280 - what is it?
Looking at the characteristics of the motherboard of a laptop, de rose M.2, you can add such a row in the description of the rose: "M key, type 2242/2260/2280". Good, s M key, I’m agreeing, I’ve already realized that the key is in roses (what to say about the PCIe × 4 bus). And what does the axis mean "type 2242/2260/2280"?
Everything is just for the sake of SSD-disks, which can be installed in every rose. Physical reconciliation. The first 2 digits are the width, which should be 22 mm. Other 2 digits - dozhina. Won can be changed and folded 42, 60 or 80 mm. For example, if the SSD is vibrated, for example, the same Crucial MX300, which can be 80 mm long, so that it can be brought up to type 2280, then there will be no daily problems with this installation.
The Transcend MTS400 SSD with a capacity of 64 GB can be up to 42 mm, so it is type 2242. As the support for such an SSD is declared, then installing it is also not important. In fact, I tell you, what are the placements on the motherboard or on the cases of the Gvint laptop, what fixes the accumulating capacity, how much are the insurance costs for the installed modules installed. The axis looks like it is on the motherboard.
Visnovok
M.2 is a compact form factor for storage SSDs. A lot of models are available both in the traditional 2.5-inch format, and in the seemingly small motherboard with an M.2 socket. If there is such a rose in a laptop or on a motherboard, then it is a good reason to put it in a new storage device. Chi zrobiti yogo systemic, chi vikoristovuvat for other purposes - besides nutrition.
I especially plan when upgrading my computer at home, so I will hack M.2 for installation in a new disk under the system. Tim himself, the trochs will run away a lot of darts, that and pratsyuvatime shvidko.
Run out of food? Bet. What am I knocking into? Get ready for constructive criticism. About schos not having proved? Let's figure it out together.
Read about the advantages and disadvantages of the M.2 form factor, which disks support an M.2 slot, which disks support M.2 disks, which is necessary for installing an M.2 card, and so on. M.2 is a price-relevant format for productive computer systems, but is everything unambiguous? Such types of SSD hard drives, such as Samsung, Intel, Plextor, Corsair, vicorist format for economy of space and energy consumption. These are also important factors in the production of modern ultrabooks and tablets. However, buying a storage unit with an M.2 socket to upgrade your add-on will require some flexibility.
M.2 is just an evolutionary form factor. Potentially, we can replace the entire Serial ATA format. M.2 can be interchanged with SATA 3.0 (all disks on current desktop PCs are connected with such cables), PCI Express 3.0 (this interface is used for locking for video cards and other devices) and USB 3.0.
Potentially, be it an SSD or a HDD drive, a memory card or a flash drive, a GPU or a USB gadget with low power can be installed on a card with an M.2 rose. But it's not all that simple. For example, in one M.2 slot there is less than a few PCI Express smogs, which make it a quarter of the number of required video cards, but the flexibility of this very small slot is hostile.
When the PCI bus is different, the SATA bus can be replaced by the M.2 add-on, which can transmit data more low for 6 times. Kіntseva shvidkіst deposit due to the possibilities of the mother's payment and the same card M.2. An M.2 SSD will work better than a similar SATA drive if your motherboard supports PCI 3.
Which drives support the M.2 slot?
At the moment, M.2 is used as an interface for over-the-counter SSD drives, both on laptops and on workstations. If you go to a computer store and power up an M.2 drive, then the stench will sing-songly show you an SSD with an M.2 socket. But only if you can find a store that sells computers from retailers, which still works in our hour.
Some laptop models also feature an M.2 port to enable a wireless connection, install low power cards, and enable Wi-Fi and Bluetooth radio. It's smaller for desktop computers, it's better to use USB or PCIe 1x roses (for no reason, for some reason you couldn't work on a big motherboard).
Computer room pickers do not hurry to win the slot of other outbuildings. While no one has presented a video card on M.2 roses, Intel is already selling its Optane memory firmware to customers.
What supports my computer M.2 slot?
If your computer has been prepared and selected for the rest of the year, then it may well have an M.2 slot. Unfortunately, the flexibility of the format does not mean that the slot itself can also be twisted just like a USB attachment. As a rule, cards with an M.2 slot can do a great deal. Before buying an M.2 SSD, please check the specifications and see if your computer or laptop has space to install them. Krym tsgogo, M.2 outbuildings can be washed with different roses. Let's take a look at the two factors and report.
Yaka dozhina pay M2?
For desktop PCs, the sound is not a problem. Fitting a Critical Mini-ITX Motherboard can easily accommodate an M.2 board, which has a 30mm to 110mm diameter. As a rule, mother's fees may be open for a little guinea pig, which drastically increases the fee on the mission. The order of the attachments is assigned to the trimmed M.2 chip.
All M.2 discs have a fixed width of 22 mm, so the difference in size is expressed only in length. At the moment the following options are available:
- M.2 2230: 30mm;
- M.2 2242: 42mm;
- M.2 2260: 60mm;
- M.2 2280: 80mm;
- M.2 2210: 110 mm.
Deyakі souls proponuyut the possibility of strengthening gwent on be-yakoy s tsikh іnvalіv.
How many roses are vicorous for M.2 disks?
Although the same 22 mm wide slot for all cards is used in the M.2 standard, it is not the same for all attachments. Scope of M.2 design for a variety of buildings without any other outbuildings
- B Key: there is a gap at the right side of the card (left-handed in the host controller), with six right-handed contacts in the gap. This configuration supports the PCIe x2 bus.
- M Key: vikoristovuє gap at the left side of the card (right side of the head controller), with five pins left hand in the gap. This configuration supports the inclusion of a PCIe x4 bus for dual data throughput.
- B+M key: vikoristovu obsva vishchezgadanі gaps, with five pins on the left side of the card and six right-handed. These cards are exchanged for PCIe x2 security.
What is required to install an M.2 card?
Most M.2 cards are SSD drives and are automatically recognized by your operating system based on AHCI drivers. For Windows 10, more Wi-Fi and Bluetooth cards are also automatically recognized and standard drivers are installed for them. However, you may need to enable the M.2 slot via a setting in your computer's BIOS or UEFI. Also, you need a spin to secure the screw on the motherboard.
Can you add an M.2 card to a PC because there is no slot in the new one?
For laptops, it is impossible, because modern attachments can already have a compact design and do not allow any unplanned attachments to the middle of the case. You are lucky, as you have won the desktop computer. For sale - adapters, like hacking the PCIe x4 slot of the motherboard.
Keep in mind that if your motherboard can't take advantage of PCIe, then you won't be able to drive an M.2 drive like it's worth it, which means you won't win big speed. If you want to beat all the features of the M.2 disk, it's better to beat the motherboard, as it supports the new standard.
So in the past, what fate of the article about SSD can be boldly started from the very same passage: “The market for solid-state accumulators stands on the back of serious changes.” It’s already been a month since I’ve been impatient to check at that moment, if the manufacturers start releasing fundamentally new models of mass SSDs for personal computers, as a replacement for the SATA 6 Gb / s audio interface, they will replace the larger PCI Express bus. But a bright moment, if the market reminds of new and significantly more highly productive solutions, everything is added and applied, the main rank through the hustle with bringing the necessary controllers to a rose. These are single models of fast SSDs with a PCI Express bus, which still become available, while still being clearly experimental in nature and cannot impress us with their swidcode.
Perebuvayuschie in such a heavy ochіkuvannі zmin, it does not matter to let them out of respect іnshі podії, yakі don't go and don't give the main injection to the whole industry, the protege is important and cіkavi. Something like this has happened to us: indefinitely, new trends have grown wider in the market of the surviving SSDs, and no respect has been given to them. The sale began to mass-produce SSDs of the new M.2 format. More importantly, this form factor was only said about a promising standard, but for the rest of the rіk-pіvtor vіn zumіv rozrakhovuvat on the size of the number of prihilnikі and the middle of the rozrobnikіv platforms, and the middle of the virobnikіv SSD. As a result, the current accumulation of the M.2 format is not a rarity, but an everyday reality. They let out a lot of virobniks, stinks are freely sold in stores and are installed everywhere in computers. Please, the M.2 zoom format doubles its place in mobile systems, which are assigned to the back of the screen. A lot of motherboards for desktop computers today are equipped with an M.2 slot, as a result of which SSDs actively penetrate into classic desktops.
Looking back at all these things, we have discussed the need to pay attention to solid-state storage devices in the M.2 format. Regardless of those that many models of such flash drives are analogues of the primary 2.5-inch SATA SSDs, which are tested by our laboratory on a regular basis, the middle of them are self-produced products, which do not look like twins in the classic form factor. That's why we vyrishili need to spend it and conduct a single link testing the largest running capacities of 128 and 256 GB, which are available in M.2 SSD stores. The Moscow company gave us help with the zdіisnennі tsієї vitіvka. Regard”, Proposes an overly wide range of SSDs, including the M.2 form factor.
⇡ Unity and diversity of light M.2
Slots and cards in M.2 format (earlier the format was called Next Generation Form Factor - NGFF) were more and more expanded as a more flexible and compact replacement for mSATA - a popular standard, based on solid-state storage devices in various mobile platforms. Ale, on the vіdmіnu vіd vіd svogo oprednik M.2 proponovuє principally greater flexibility like in the logical part, so in the mechanical part. The new standard describes some options for up to the width of the cards, and also allows for the connection of solid-state storage devices such as SATA, as well as a PCI Express PCI Express interface.
The one who changes PCI Express interfaces for us storage devices has no need for money. Bezperednє vykoristannya tsієї bus without additional overheads allows you to reduce the latency in the case of animals to data, and the zavdyaks of її scalability of the bus will increase the throughput of the building. Add two lanes of PCI Express 2.0 to secure more data transfer speed with a single SATA 6 Gb/s primary interface, and the M.2 standard allows you to install data from an SSD from one to two PCI Express lanes. In this way, the foundation for the increase in throughput of buildings is caused by the emergence of a new generation of high-capacity solid-state accumulators, building security, more advanced operational system and supplements, as well as a change in jamming when moving significant data.
| SSD interface | Maximum theoretical throughput building | Maximum real throughput capacity (estimation) |
| SATA III | 6 Gb/s (750 Mb/s) | 600 MB/s |
| PCIe 2.0x2 | 8 Gb/s (1 Gb/s) | 800 MB/s |
| PCIe 2.0 x4 | 16 Gb/s (2 GB/s) | 1.6 GB/s |
| PCIe 3.0 x4 | 32 Gb/s (4 GB/s) | 3.2 GB/s |
Formally, the M.2 standard is a mobile version of the SATA Express protocol described in the SATA 3.2 specification. However, it turned out that for the last couple of years M.2 has expanded richly wider than SATA Express: M.2 roses can now be seen on current motherboards and in laptops, and SSDs in the M.2 form factor are everywhere available for sale. SATA Express is similar to the side of the industry to boast of not a building. Often it is connected with the greater flexibility of M.2: depending on the implementation of this interface, it can be more complex with attachments that work behind the SATA, PCI Express and USB 3.0 protocols. Moreover, in its maximum version, M.2 supports up to two PCI Express lines, as well as SATA Express roses, to ensure the transfer of data for only two such lines. In other words, today's M.2 slots themselves are not only an easy, but a promising foundation for future SSDs. The stench is not only suitable for mobile, and for desktop zastosuvans, but also for buildings, it’s safe to get a pass through the building in the middle of the options for connecting to slow-moving solid-state storage devices.
However, looking at the fact that the key power of the M.2 standard is the versatility of one type, next to the other, far from all M.2-accumulating slots are the same, but their confusion with various options for different slots is a story. Almost from the fact that the available on the market solid-state storage devices in the M.2 form factor may have a width of 22 mm, but there are five options for length: 30, 42, 60, 80 or 110 mm. It is given the scalability to know in the marking, for example, the M.2 2280 form factor means that the card can accumulate a width of 22 mm and a length of 80 mm. For M.2 slots, sound the latest change in storage card sizes, with which stench can be physically combined.
Another sign to make differentiation in different M.2 variants is the "keys" in the slot and, apparently, in the knife rose of the cards, as if changing the settings of the accumulator boards into logically inconsistent roses with them. At the moment, for M.2 SSD, there are two options for the distribution of keys from the descriptions in the specification of eleven different positions. Two more options are known to be stuck on WLAN and Bluetooth cards in the M.2 form factor (for example, this is the Intel 7260NGW wireless adapter), and this position of the key is reserved for the future.
M.2 slots can have more than one key-partition, but M.2-cards can have multiple keys-virizivs in a row, so that you can rob them with the sum of all types of slots at once. Key type B, numbered 12-19, which means that the slot has been allocated no more than two PCI Express lines. A key of type M, which occupies contact positions 59-66, means that the slot can be connected to the PCI Express line and, therefore, it can provide more high productivity. In other words, the M.2 card is not only to blame for the rozmіrom, but also the mother of the bag for the slot of rozashuvannya keys. This key is used to interleave the mechanical summation between different sockets and M.2 form-factor boards, and also to add one more function: reshuffling the wrong installation of accumulators in the slot.
The information provided in the table is to help you correctly identify the type of slot that is in the system. Ale requires memory, scho the possibility of mechanical slot sticking and roz'mu є is only necessary, but with a sufficient mental їx logical totality. On the right, in the slot with the B and M keys, you can see not only the PCI Express interface, but also the SATA interface, the prototyping of the keys does not give any information about it, or the presence. Those same stosuєtsya and roses M.2 cards.

| Extended SSD Models | Hi | Samsung XP941 (PCIe x4) | Bigger M.2 SATA SSD Plextor M6e (PCIe x2) |
One more problem. Vaughn argues that a lot of motherboard retailers ignore many specifications and install the most “cool” slots with a type M key on their products, but only run two or more PCIe lines on them. In addition, M.2 slots found on motherboards may not interfere with SATA drives. Zokrema, ASUS will sin with its love until the installation of M.2 slots from the reduced SATA functionality. On the cycles, the SSDs are adequately supported, many of which allow work on their cards to immediately offend the keys-viruses, lower stinks ensure the possibility of physical installation of storage devices in the M.2 slot, no matter what type.
As a result, it is impossible to indicate the real possibility, the summancy and the presence of the SATA interface in the slots and roses of M.2 behind some more obvious signs. Therefore, more information about the specifics of the implementation of quiet slots and accumulative capacity can only be taken from the passport characteristics of a particular building.
Luckily, the range of M.2 storage devices is not very large, so the situation did not become completely confusing. In fact, there is only one M.2 storage device with PCIe x2 interface - Plextor M6e - and one model with PCIe x4 interface - Samsung XP941. All others are available in flash storage stores in the M.2 form factor with the primary SATA 6 GB / s protocol. If so, everything that is sounded at the M.2 SSD vacancies stores, there are two keys each - at the B and M positions. It’s more like Samsung XP941, at least one key is at the M position, and Russia has only one key not for sale.
Prote it in the computer or on the motherboard there is an M.2 slot, and you plan to store it with a solid-state storage device, you will need to transcribe some speeches in advance:
- What supports your system M.2 SATA SSD, M.2 PCIe SSD or other storage options?
- If the system has an M.2 PCIe drive, how many PCI Express lanes are connected to the M.2 slot?
- If the key distribution on the SSD card allows an M.2 slot, what is in the system?
- What is the maximum length of an M.2 card, what can be installed on your motherboard?
As soon as you can vary the performance on all power supplies, you can move on to choosing the appropriate SSD model.
For the sake of understanding, as a difference between M.2 SSD and 2.5-inch SSD and mSATA, there are different types of connections to the motherboard of a laptop or PC.
Three hours after the creation of the classic SSD 2.5 ”drive, it took enough time for new form factors to appear, such as mSATA SSD, M.2 SSD and NVMe. In this article, we consider this technology, like NVMe, which is recognized as standard disks that work on SATA buses, and that all M.2 disks are classified as NVMe.
The first step is to buy ssd m2 NVMe, you will be sorted out, which type of accumulator will support your computer or laptop motherboard. Although with the form factor SATA 2.5 and mSATA everything is clear, then with M.2 it is not so simple.
Practically all PC motherboards have versions with SATA storage, but not all versions with M.2 storage. Just do it with motherboards in laptops. Older laptops have less than SATA 2.5” storage and maximum you can install SATA SSD storage, but more modern laptops have additional roses on motherboards with M.2 storage.
If your motherboard has such a slot, as shown in the photo above, then you can install M.2 storage.
And everything would be wonderful, the yakby M.2 Slot was of the same type and the M.2 itself would pay less than one size. Ale, let's do everything in order, let's look at the types of boards.
Tipi SSD M2
Accumulator M.2 is used in several subtypes: 2230, 2242, 2260 and the most popular 2280. The first two digits indicate the width of the board, the other two digits indicate the depth.
Now, if you know which slot is on the motherboard and how M.2 storage is supported by your board, let's move on to the type of slot.
Є 2 types of bus on which M2 works, not SATA bus or PCIe bus, and also є slot type with "M" and "B" keys.
As a rule, M2 is accumulative, which works on SATA buses, supports 2 keys "M" + "B". Accumulator SSD M2 NVMe, which works on PCIe and AHCI buses, will be with one “M” key.
From the butt in the picture you can see that the M2 SATA SSD board with the M + B key can install more slots, just like the M2 NVMe SSD with the “M” key, it’s physically impossible to install it in the “B” slot, so please respect that the slot itself is installed on your mother board of the computer. If you need more detailed information about the interface and keys, you can look at wiki .
Why M2 and NVMe?
M.2 is just a form factor. M.2 storage can be used with SATA versions (for example, M.2 Samsung 860 EVO) and NVMe versions (for example, Samsung 970 EVO)
As you can remember, two people pay even similar calls, but there may be a small difference in connection roses. SATA M.2 SSDs and 2.5-inch SATA SSDs are virtually the same performance. Storage NVMe M.2 works on the PCIe bus, and there are other indications in the throughput, the stench is significantly lower on the SATA bus.
What is NVMe
NVMe is the definitive standard for "non-volatile Express memory", which allows today's solid-state storage devices to work with read/write speed, on which flash memory is built. In fact, such a pidhid allows SSD flash memory to be processed without intermediary through the PCIe interface, and not through the outdated SATA technology. In other words, NVMe is a description of a bus, like a component for electrical communication with a PC, and not a new type of flash memory. It also has nothing to do with the form factor, so NVMe storage can be mothers of form factor M.2 or PCIe cards. With both form factors, the component is electrically connected to the PC via PCIe rather than via the SATA bus.
Modern motherboards use SATA III with a maximum bandwidth of 600 MB/s (or 300 MB/s for SATA II). Zavdyaki z'ednannyu more solid-state storage devices provide read / write speed close to 530/500 MB / s. For comparison: a SATA disk with a speed of 7200 rpm will provide a speed of about 100 MB / s in the future, which will become a stage of fragmentation. The NVMe storage device ensures write speed up to 3500 MB/s. The price is 7 times higher, lower for SATA!
SSD M2
We have sorted out the types, sizes and working M2 buses, now let's sort out the M.2 SSD from your PC or laptop.
A lot of options are installed on the motherboard slot for M.2 with the “M” key and with the bus support for the choice - SATA or PCIe. So you buy M.2 SATA or M2 NVMe and you will work.
But there are some drawbacks, if the motherboard works only on one of the two buses, and does not support, for example, the new NVMe standard or the old SATA. In order to perekonatisya in the summation of your motherboard with accumulating SSD M2 accumulating, I'll show you a butt with an Asus motherboard.
We go into the BIOS, then in the Advanced section and we know the “M.2 Configuration” row, from the menu you can find out that the motherboard supports the SATA and PCIe bus, and also on such a motherboard you will use the M.2 SSD like SATA, so and NVMe.
Well, looking at the advantages of NVMe storage capacity, it is impossible to change your respect when upgrading your PC or laptop. The higher price of ssd m2 nvme is more suitable for your budget, especially as your program, because you often use hard disk hard disk or it helps to permanently read / write hard disk.
Video
Become all popular through numerical superiority. The stench of miniatures expands and does not take up a lot of space in a laptop, mini-PC or a desktop computer case (they are installed directly on the motherboard), at the same time they allow access to the speed of the inaccessible “magnificent” 2.5-inch SSD.
It is necessary to know that M.2 SSD drives are available in different formats (they can vary in length), as well as the two main variations - the SATA interface (cheaper and better), that the PCI Express / NVMe interface (more expensive and smarter). The SATA interface, which is being played at the moment, allows you to reach the maximum bandwidth of 6 Gb / s, while PCIe x4 is up to 32 Gb / s, so the difference in productivity can be even greater, like the price.
Let's talk about the memory of Intel Optane (don't confuse with Intel Optane SSD), if you can use the M.2 format, or use it to speed up HDD disks. This technology is used only on new Intel platforms, but it works out of the blue, allowing you to significantly increase the speed of magnetic disks.
M.2 sockets on motherboards can support standards, but only one - just check before buying, so that, for example, you won’t be able to install a PCIe / NVMe drive in M.2 sockets with support for the SATA standard. Note that M.2 PCIe storage can also be plugged into a U.2 port (via an adapter) and up to a PCI Express slot.
Below are the Most Efficient SSD Designs, like changing the PCI Express x4 3.0 (NVMe) bus, so cheaper / less expensive models, like changing the SATA standard.
Inexpensive SSD accumulator M.2
Among cheap M.2 drives, how can you know the designs, such as SATA and PCIe. The capacity of the first ones is close to 2.5-inch SSDs, but they seem to be more expensive, and also those that some computers can not support M.2 NVMe drives.
WD Green PC SSD G2 (120 GB)
The WD Green PC SSD G2 series is one of the found M.2 options. Based on the SATA interface, and the productivity of the 120 GB model reaches 545 MB / s when reading and 430 MB / s when writing data. Virobnik zastosuva here 4-channel controller Silicon Motion SM2246XT and the middle memory Toshiba 3D TLC NAND (but without cache memory).
