Solid-state storage has changed, and it can now be found inside the thinnest laptops and in the motherboard cavities of the newest desktop PCs. It’s understandable if you weren’t even aware that it was happening, even if you keep a careful eye on all things technological.
This is so that the storage hardware itself may be made nearly undetectable, which is the whole point. Solid-state drives (SSDs) have evolved over the past few years from the slab-like designs of common hard drives into tiny sticks of memory that provide roughly the same capacities. Along the way, they increased their speed.

4 For PC modders, the best M.2 SSD SHORT VERDICT: Unapologetically bright RGB-lit M.2 SSD that blings up your PC is the ADATA XPG Spectrix S40. The majority of gamers should be content thanks to its 4K read and write speeds.
PROS Excellent sequential read and write results in 4K. powerful value proposition For PC builders, RGB lighting is a fun feature. CONS There are several issues with preserving RGB settings when using different profiles. The conventional SSD employs what’s referred to as the “2.5-inch drive” form size, which you can purchase and install in a desktop PC or in place of a hard drive in a laptop. The drives are 2.75 inches broad in truth. These SSDs are the same size as hard drives used in laptops. In order to make SSDs compatible with current laptop models, SSD manufacturers selected this standard size. (Without any retooling, they could configure laptops with the option of a hard disk or an SSD.) Desktop PCs, on the other hand, could easily support SSDs of this capacity. They might be mounted in a 3.5-inch drive bay with the aid of a straightforward bracket or even just by using different mounting holes in the same locations. Additionally, throughout time, 2.5-inch drive mounting points and their own bays have been added to desktop PC chassis.
However, SSDs didn’t have to be so huge from an engineering standpoint. There is a lot of empty space inside the enclosure an SSD is sent in. Its 2.5-inch size and shape are intended to allow the drive to fit into those existing bays. Therefore, when mobile device designers reevaluated this issue in order to shrink down laptops and tablets, the conclusion was unanimous: eventually, the unwieldy 2.5-inch form factor would have to disappear.
An SSD is essentially just a tiny circuit board with controller and flash memory chips embedded in it. Why not construct that?
THERE WAS MSATA AT THE OUTSET… Mini-SATA, often known as mSATA, was the first attempt. An mSATA drive is a blank, rectangular circuit board that has had the outer casing removed—it is an SSD down to its bare essentials. (The majority of upgraders’ mSATA drives are around 1 by 2 inches in size.) mSATA drives can be installed in a specific slot on the motherboard of a PC or the logic board of a laptop. The slot connects to the system’s Serial ATA bus, as its name suggests. Instead of the standard SATA cable, the interface at the drive end is a PCB edge connector. Additionally, the mSATA drive receives all the power it need from the slot.
6 (Zlata Ivleva credit) The shape issue comes first, though. Any M.2 drive you are considering will have a four- or five-digit number written on it as part of its product name or specs. In millimeters, it is a measurement: The drive’s width and length are determined by the first two values, respectively.
As a result of the aftermarket drives that are readily available and the accessible slots that we’ve seen, the market has decided that 22mm wide is the industry standard for desktop and laptop implementations. We’ve seen lengths in the 80mm (“Type-2280”) and 60mm ranges most frequently (“Type-2260”). Although length isn’t a precise indicator of capacity, the longer the drive, the more NAND chips you can typically fit on it (besides, M.2 drives can be single- or double-sided).
8 (Credit: Zlata Ivleva) The PCI Express Gen 2.0 x2 interface, which establishes a throughput ceiling that is higher than SATA 3.0’s, but not much, was used in the first iterations of M.2 PCI Express SSDs. This evolved into PCI Express Gen 3.0 x2 and x4, which increased speed even more, especially with demanding, deeply queued workloads, by combining NVMe technology.
The PCI Express bus’s most recent iteration, PCI Express 4.0, is located after that. It has quickly gained popularity, but it still typically denotes a higher-end drive. Some devices (like Samsung’s flagship SSD 980 Pro) boast read and write speeds of up to 7,000MBps. These drives are compatible with the most recent mobile platforms as well as desktop computers running AMD and Intel chipsets. For AMD, those are the AMD TRX40, X570, and B550 chipsets (for popular Ryzen CPUs) (for third-generation Ryzen Threadripper ones). With Intel, PCI Express 4.0 is supported on chipsets from the 500-series that operate with desktop CPUs from the “Rocket Lake” generation, laptops from the newest “Tiger Lake” 11th Generation mobile platform, and later “Alder Lake” 12th Generation platforms.
These PCIe 4.0-based SSDs can be used in older AMD and Intel processor systems that support PCI Express 3.0, however they will simply default to PCIe 3.0 speeds. Next, what? In 2022, many desktop motherboards should support PCIe 5.0, but the even faster-rated SSDs won’t be available until then.
NVME is another technical barrier because systems and motherboards need board-level support for these devices in order for them to be bootable. MEET NVME: THE SPEED BOOSTER NVMe M.2 drives are currently supported by all recent motherboard models, while older boards may not be able to boot from an NVMe-based disk. These high-bandwidth, NVMe-capable slots are not only present in some modern motherboards but also in some current laptops. Also keep in mind that a PCI Express NVMe drive might be supported by a laptop in some circumstances, but it might be soldered to the motherboard and not upgradeable. Therefore, before purchasing one of these drives for a current laptop or convertible, make sure to carefully read your handbook.
0 Submitted by Molly Flores Identify the bus you are riding. You almost definitely replace one M.2 drive with another when upgrading a laptop in order to increase capacity. To install the same, presumably roomier sort going in, make sure you are aware of the characteristics of the drive exiting your system and whether it relies on the SATA or PCI Express bus.
On a PC, it’s a little more difficult. Both SATA-bus and PCI Express-bus M.2 drives can be used in the same M.2 slot on some motherboards. Others only support PCI Express M.2 drives, while still others only support SATA M.2 drives (those will be older boards). (And not all older motherboards enable PCIe x4 or NVMe in the case of PCI Express M.2) You must be aware of the capabilities of your board before making purchases. In all other respects, a PCI Express SSD should be faster than a SATA one, but for general use, a SATA SSD will work just as well and, in many circumstances, be identical to a PCI Express SSD.
Additionally, search for PCI Express 4.0 functionality in the newest drives. If you purchase one of those, you must have a motherboard that is current AMD or Intel models. Recheck the specifications. A PCIe 4.0 drive should function, albeit more slowly, in a PCI 3.0 only slot.
Verify the bootability. Verify with the board manufacturer that an M.2 SSD of the bus type you are considering will be bootable before installing one for the first time in a desktop board. Even though it’s improbable, an older motherboard can require a BIOS upgrade.
Examine the price per gig. The primary metric used to price-compare comparable M.2 drives from various manufacturers is cost per gigabyte. All things being equal, expect to pay more for PCI Express bus models and more for PCIe 4.0 drives than PCIe 3.0 ones. However, in both cases, the cost disparities are getting smaller. The cost per gig is calculated by dividing the drive’s price (in dollars) by its capacity (in gigabytes). For instance, the price of a 1TB (1,000GB) drive comes out to around 10 cents per gigabyte. When evaluating various drives, use this as a criterion for value.
