The Finest M.2 SSDs (Strong State Drives) for 2026
Examine Specs
Shopping for Information: The Finest M.2 SSDs (Strong State Drives) for 2026
The normal SSD which you could purchase and set up in a desktop PC, or instead of a spinning exhausting drive in an older laptop computer, makes use of what’s often called the “2.5-inch drive” type issue. (In truth, the drives are about 2.75 inches extensive.) These SSDs have the identical dimensions as laptop-style exhausting drives. Years again, SSD makers adopted this customary dimension to make SSDs suitable with current laptop computer designs. (Because of this, laptop computer makers might configure laptops with the selection of a tough drive or an SSD with none retooling.)
Desktop PCs, in the meantime, might accommodate SSDs of this dimension with little fuss. You possibly can mount them in a 3.5-inch drive bay utilizing a easy bracket, or typically even use different screw holes spaced for two.5-inch drives in those self same trays or mounting areas. Over time, too, desktop PC chassis have developed to achieve devoted bays and mounting factors for two.5-inch drives. Certainly, many desktop PC circumstances now have extra 2.5-inch drive mounts than trays for greater 3.5-inch exhausting drives.
Nonetheless, from an engineering perspective, SSDs did not want to be that enormous. The enclosure that an SSD is available in has numerous useless house inside. It is designed in that 2.5-inch dimension and form to suit the drive into these current bays. So when mobile-device designers, challenged with slimming down laptops and tablets, reassessed this subject, the consensus was clear: The cumbersome 2.5-inch type issue would ultimately should go.
At its core, an SSD is only a skinny circuit board studded with flash reminiscence and controller chips. Why not design round that? Thus, the M.2 type issue was born. However we’re getting forward of ourselves.
A Brief Historical past of Small SSDs: mSATA to M.2
The primary try was a brand new type issue known as mini-SATA (mSATA). The boiled-down essence of an SSD with the shell eliminated, an mSATA drive is a naked, rectangular circuit board. (Most mSATA drives related to upgraders measure about 1 by 2 inches.) mSATA drives match right into a devoted mSATA slot on a laptop computer’s logic board or a PC motherboard. Because the title suggests, the slot is a conduit to the Serial ATA bus within the system. The interface on the drive finish is an edge connector on the PCB quite than the same old SATA cabling. The mSATA drive additionally attracts all the ability it wants by the slot.
(Credit score: HP)
By counting on SATA, mSATA drives gained all the benefits and limitations of that interface, together with the higher velocity restrict of SATA 3.0, the newest revision of Serial ATA. That is not a nasty factor, thoughts you. mSATA was additionally uncommon as a result of it piggybacked on an current connector, often called Mini-PCI, which is usually used to put in small onboard elements, corresponding to compact Wi-Fi playing cards.
Now, a couple of mSATA drives nonetheless linger available on the market, primarily as a result of some older laptop computer fashions adopted the shape issue years in the past, and residual demand exists attributable to capability upgrades. Nonetheless, it is a useless type issue, and mSATA noticed solely slight adoption on desktop programs.
Even in mSATA’s heyday, a substitute was within the works. Throughout growth, it was often called NGFF, for “Subsequent-Era Type Issue.” Because it took form, it took on its present, ultimate title: M.2. The drives can be smaller, probably extra capacious, and, most essential, not essentially reliant on the SATA bus.
What Is an M.2 SSD?
M.2 drives are as utilitarian as upgrades come: They seem like sticks of gum studded with NAND modules and a controller chip. (“NAND” is the generic time period for the flash-memory chips that make up the precise storage on the SSD; the time period refers, technically, to the kind of logic gates used within the underlying reminiscence construction. See our primer Shopping for an SSD: 20 Phrases You Must Know for extra SSD lingo defined.)
The essential factor to recollect about M.2 is that it’s a type issue, a form. The bus—the information pathway the information travels to and from an M.2 drive—is distinct from M.2 itself and may fluctuate. And it might probably make all of the distinction when it comes to velocity and compatibility.
(Credit score: Joseph Maldonado)
However first, the form subject. Any M.2 drive you’re looking at might be labeled with a four- or five-digit quantity as a part of its specs or mannequin title. It is really two measurements, in millimeters. The primary two numbers outline the drive’s width, and the second two or three numbers outline the size.
The market has settled on 22mm extensive as the usual for desktop and laptop computer implementations; the aftermarket drives out there and the accessible slots we have seen have all been that width. The commonest lengths are 80mm (“Sort-2280”) and 60mm (“Sort-2260”). The longer the drive, the extra NAND chips you’ll be able to match on it (plus, M.2 drives could be single- or double-sided), although word that size is not an absolute measure of capability.
42mm, 60mm, and 80mm M.2 SSDs (Credit score: Intel)
Now, why does size matter? Match, particularly when speaking about laptops. Most desktop motherboards with M.2 slots have screw-mounting factors for a number of lengths of M.2 drive (normally 80mm, 60mm, and 42mm), so size hasn’t been a problem. Nonetheless, it is a completely different matter with a laptop computer that has a user-accessible M.2 slot. The bay could also be space-limited to M.2 drives of a selected dimension, or solely to single-sided modules if the thickness tolerances are tight. You will wish to verify the out there house earlier than purchasing.
The most recent era of M.2 drives, utilizing the PCI Categorical 5.0 bus, additionally come within the Sort-2280 format. M.2 drive size is not all the time an indicator of drive capability, however there are limits to NAND-chip density and what number of reminiscence modules engineers can stuff onto a PCB of a given dimension. Because of this, most M.2 drive households we have seen so far have topped out at 2TB or 4TB, although you could find a couple of 8TB fashions at lofty costs, and enterprise-class 16TB M.2 modules do exist. The standard capability waypoints are as follows:
120GB or 128GB
240GB, 250GB, or 256GB
480GB, 500GB, or 512GB
960GB or 1TB
2TB, 4TB, and 8TB
Smaller-capacity 32GB and 64GB M.2 SSDs are additionally out there for embedded functions or SSD caching, however they’re of marginal curiosity to upgraders or PC builders. Pricing for these drives ranges from 6 to 75 cents per gigabyte, and probably the most important issue affecting worth is the drive’s bus kind.
Now, to reiterate an essential level: A drive could come within the M.2 type issue, however that claims nothing concerning the bus it makes use of. Figuring out that’s simply as essential as ensuring it suits.
PCI Categorical vs. SATA: The Two Fundamental SSD Buses, Defined
That is the trickiest a part of an M.2 SSD improve. A lot of the early M.2 drives have been merely odd SATA drives stripped right down to their fundamentals: a naked circuit board with a distinct bodily connector, however at coronary heart, the identical drives as their bigger 2.5-inch counterparts. A few of them nonetheless are. You will not see higher efficiency with these M.2 SATA drives versus their 2.5-inch SATA equivalents, as a result of finally your knowledge is touring alongside the identical internal pathways inside the pc as soon as it leaves the drive.
That is not a nasty factor. Particularly with laptops, an older machine would possibly help solely M.2 SATA SSDs, and that would be the restrict of your improve path…finish of story. Because of this, the one causes you’d improve the drive, in that state of affairs, can be to get extra capability, or if the previous one failed.
These days, nonetheless, lean, premium laptops can make the most of PCI Categorical-based M.2 SSDs. (All new desktop motherboards with M.2 slots additionally help PCI Categorical M.2 SSDs.) These will present a considerable improve in efficiency in benchmark testing over SATA SSDs, however in most real-world use circumstances, they’re going to really feel a lot the identical as a quick, premium SATA SSD.
(Credit score: Joseph Maldonado)
The earliest variations of M.2 PCI Categorical SSDs used the PCI Categorical Gen 2.0 x2 interface, which defines a throughput ceiling larger than SATA 3.0’s however not enormously so. That developed into PCI Categorical Gen 3.0 x2 and x4, paired with a expertise known as Non-Risky Reminiscence Categorical (NVMe) to propel efficiency even additional, particularly with heavy, deeply queued workloads.
Past that’s PCI Categorical 4.0, a more recent model of the PCI Categorical bus. It has quickly gained traction and, normally, signifies a quick drive. The learn and write speeds for some are rated as excessive as 7,000MBps. These drives are supported on current desktop programs with current AMD and Intel chipsets, in addition to on the newest cellular platforms. For AMD, that’s the X570 and B550 (and later) chipsets (for mainstream Ryzen CPUs) and the AMD TRX40 and later (for Ryzen Threadripper). With Intel, PCI Categorical 4.0 is supported on Intel 500-series and later chipsets that work with eleventh Gen and later desktop CPUs, or on laptops constructed on eleventh Gen and later cellular platforms. You will wish to confirm that particular help within the PC’s specs, nonetheless.
You should use these PCIe 4.0-based SSDs in older AMD- and Intel-chipset programs that help PCI Categorical 3.0, however they’re going to run at slower PCIe 3.0 speeds. Quick on PCIe 4.0’s heels, although, is PCIe 5.0. A lot of the very newest desktop motherboards already help it, however take into account that PCIe 5.0 M.2 SSDs are top-end picks. Additionally, word that simply because a motherboard helps the PCIe 5.0 bus does not imply the board maker essentially included a PCIe 5.0-capable M.2 SSD slot. (The 5.0 help could solely be prolonged to odd PCIe x16 enlargement slots.) Once more, verify these specs!
What Is NVMe? An SSD Velocity Booster
We talked about NVMe above. NVMe is one other technical hurdle to think about, as a result of programs and motherboards want board-level help for these drives to be bootable. All late-model motherboards now help NVMe M.2 drives, however older boards could not help booting from an NVMe drive. Exterior of latest desktop motherboards, these high-bandwidth, NVMe-capable slots are discovered in lots of current laptops. Additionally word that in some circumstances, a laptop computer could help a PCI Categorical NVMe drive, however it might be soldered to the motherboard and thus not upgradable. In the event you’re contemplating upgrading a current laptop computer or convertible, seek the advice of your guide or on-line technical documentation intently earlier than buying certainly one of these drives.

Amongst M.2 drives, PCI Categorical 3.0 and 4.0 x4 M.2 drives that help NVMe at the moment are the norm amongst aftermarket purchases. These are impressively quick drives, outpacing even the quickest SATA-based SSDs and exhausting drives. However know that they’re extra related for PC builders or of us upgrading comparatively current programs quite than older PCs, which can not have an M.2 slot, or could have an M.2 slot however not one which helps PCI Categorical and NVMe—solely SATA-based M.2. So, as we mentioned within the earlier paragraph, guarantee that your system helps this type of drive earlier than selecting one up. You do not wish to convey residence one of many quickest shopper drives out there solely to seek out your system cannot use it.
Tips on how to Determine Out M.2 Compatibility With Your PC
OK, again from Planet NVMe. At the moment, the true alternative in case you’re M.2-shopping might be between primary SATA and PCI Categorical M.2 drives, and for many customers, these choices might be dictated just by what your motherboard or laptop computer can settle for. A cautious browse of help boards or a name to the seller’s help line ought to unravel the M.2 bus-compatibility particulars. On the desktop aspect of the aisle, some M.2-equipped motherboards help each sorts, though not essentially on all slots.
Advisable by Our Editors
In the event you’re trying to improve an aged desktop however your PC’s motherboard would not have an M.2 slot in any respect, one incidental choice is what we name an “M.2 drive on a card” or an AIB SSD (for “add-in-board SSD”). We have seen options like this from storage stalwarts corresponding to OWC and Kingston. Moreover, a few of Asus’ and MSI’s high-end motherboards supply an M.2 PCI Categorical 4.0 “service card” to complement their boards’ on-board M.2 slots. These merchandise allow you to mount an M.2 drive (or drives) on a PCI Categorical enlargement card and faucet their velocity by the full-size PCI Categorical slots in a desktop PC that lacks sufficient M.2 slots. Some such playing cards help as many as 4 M.2 drives.
We like these as a result of they usually include a sturdy warmth sink on the M.2 drive(s). Some PCI Categorical-based M.2 SSDs can run scorching throughout sustained learn/write operations and throttle their efficiency. That mentioned, until you are working a server or one thing related the place a drive is consistently subjected to intense learn and write exercise, you normally need not fear about it. That is as a result of many of those drives are so quick, they get their switch duties performed earlier than they’ll get all that scorching.
One final caveat to debate earlier than our product suggestions surrounds Intel’s former SSD line. For some time, Intel offered a household of M.2-based storage merchandise underneath the model title Optane in two very distinct sorts of drives. Intel’s “Optane SSDs” have been SSDs like another, bootable drives that may function a stand-alone boot drive or as secondary storage. They have been discontinued for customers in 2021, however you should still see the Optane title round. (Intel offered its SSD enterprise on the finish of 2021 to SK Hynix, which spun it off into a brand new subsidiary, Solidigm.)
Intel’s “Optane Reminiscence” is a distinct animal. That is an M.2-format module that seems like an SSD however serves as an accelerating cache for one more drive, normally a tough drive. You possibly can learn extra about Optane Reminiscence in our deep-dive evaluation of the primary era. It is a useless duck now; we solely point out it as a result of chances are you’ll run into it in case you improve a laptop computer or desktop from various years in the past. In the event you can, exchange the exhausting drive and the Optane module with a vanilla M.2 SSD if the PC helps it; you will in all probability should reinstall the working system to make all of it work. Higher but, improve the entire PC, as a result of it’s in all probability greater than 5 years previous.
M.2 Upgrades and Boot Drives: What to Look For
Welcome to the innovative! You are searching for a form of drive that many of us do not even understand exists. Because of this, you should take note of a number of elements that might not be documented effectively when you store. Let’s go forward and recap.
Examine the bodily dimension. Make sure the width and, particularly, the size (expressed in millimeters) will match throughout the out there house for the drive. (That is primarily a problem with laptops.) Most might be 22mm extensive, however the size varies: 42mm, 60mm, 80mm, and 110mm are the usual sizes, with 80mm being the most typical for each customary desktop and laptop computer upgrades. Many desktop motherboards’ M.2 slots can accommodate a number of drive lengths by way of a mounting put up that may be repositioned from gap to gap.
Know which bus you are on. In a laptop computer improve situation, you are nearly actually swapping out one M.2 drive for one more to extend capability. (Only some laptops have multiple M.2 slot.) Ensure you know the specs of the drive popping out of your system—and whether or not it is reliant on the SATA or PCI Categorical bus—so you’ll be able to set up the identical, presumably roomier variety moving into.
For a desktop, it is a bit trickier. Some motherboard M.2 slots help SATA-bus or PCI Categorical-bus M.2 drives on the identical slot. Others help solely SATA M.2 drives (these might be older boards), whereas others help solely PCI Categorical M.2 drives. (And, within the case of PCI Categorical M.2, not all older motherboards help PCIe x4 or NVMe!) You could know what your board can use, and purchase accordingly. All else being equal, PCI Categorical ought to present a velocity enhance over a SATA mannequin; these days, go for PCI Categorical if in case you have a alternative.

Additionally, search for PCI Categorical 4.0 and even PCIe 5.0 help with current drives. In the event you purchase a type of, you will want a compliant late-model AMD or Intel motherboard to totally leverage their velocity. Once more, verify the specs to keep away from overbuying in your system.
Examine for bootability. In the event you’re putting in an M.2 SSD in a desktop board for the primary time, confirm with the board maker that an M.2 SSD of the bus kind you might be contemplating might be bootable. Although unlikely, a BIOS improve could also be essential with an older motherboard. This may not be a problem with boards from current years.
Examine the associated fee per gig. Value per gigabyte is the first yardstick for pricing-comparing related M.2 drives from completely different makers. Anticipate to pay extra for PCI Categorical bus fashions, all else being equal, and extra for PCIe 4.0 drives than for PCIe 3.0 ones (and extra for PCIe 5.0, in contrast with PCIe 4.0). Nonetheless, the associated fee variations are narrowing in each circumstances. Divide the value (in {dollars}) by the drive capability (in gigabytes) to get the associated fee per gigabyte. For instance, a 1TB (1,000GB) drive promoting for $99 prices about 10 cents per gigabyte. Use this as a price yardstick for evaluating completely different drives.
