Though it can't quite match the gaming prowess of some of the latest generation of PCIe 4.0 speedsters, the 990 Pro with Heatsink still offers respectable gaming performance while being a thoroughbred workhorse for creative tasks. It's an appealing choice and a worthy upgrade from the 980 Pro.

But first, the shape issue. Any M.2 drive you are looking at will be labeled with a four- or five-digit number as part of its specifications or model name. It's a measurement, in millimeters: The first two numbers define the drive's width, the second two the length.Random Read (4 KB, QD32) Up to 620,000 IOPS * Performance may vary based on system hardware & configuration In our tests, the Intel 670p loaded Final Fantasy at the same speed or faster than competitors. It also finished just two places below the vaunted PCIe 4.0 Samsung 980 Pro in PCMark 10. Those are very respectable marks for a budget drive. Az M.2 típusú meghajtók többsége 80 mm széles és 22 mm mély, azonban léteznek ennél rövidebb vagy hosszabb változatok is. Az egyszerűbb beazonosíthatóság érdekében az elnevezés időnként tartalmazza a méreteket is. Az előzőekben ismertetett mérettel például M.2 Type-2280 néven is találkozhat.

The key thing to remember about M.2 is that it is a form factor, a shape. The bus—the data pathway over which the data travels to and from an M.2 drive—is distinct from M.2 itself and can vary. And it can make all the difference. The market has settled on 22mm wide as the standard for desktop and laptop implementations; the aftermarket drives available and the accessible slots we've seen have all been that width. The most common lengths we've seen are 80mm ("Type-2280") and 60mm ("Type-2260"). The lengthier the drive, the more NAND chips you can tend to stuff on it (plus, M.2 drives can be single- or double-sided), though know that length isn't an absolute measure of capacity. 42mm, 60mm, and 80mm M.2 SSDs Nowadays, though, many lean, premium laptops can make use of PCI Express-bus M.2 SSDs. (Just about all new desktop motherboards with M.2 slots also support PCI Express M.2 SSDs, too.) With these, you may see a substantive increase in performance in benchmark testing, but in most real-world usage, they'll just feel like a fast, premium SATA SSD. Restrained by the SATA interface, but still need the absolute highest endurance and performance you can get? As the pinnacle of SATA performance inside and out, Samsung’s 860 PRO is the SSD to buy. Know which bus you're on.In a laptop-upgrade scenario, you're almost certainly swapping out one M.2 drive for another, with the intent of gaining capacity. Make sure you know the specifications of the drive coming out of your system—and whether it's reliant on the SATA or PCI Express bus—so you can install the same, presumably roomier kind going in.

Az otthoni felhasználók számára szánt SSD-k kapacitása 120 GB-tól egészen 2 TB-ig terjed. Habár a tárhely kis mennyiségéből adódóan a 120 GB-os típusok a legolcsóbbak, ekkora kapacitás gyorsan szűkössé válhat, amikor már operációs rendszert és további programokat is szeretne rá telepíteni. Arról nem is beszélve, hogy egy adott SSD termékcsalád eltérő kapacitású modelljei közül mindig a legkisebb tárhelyű változat fog a legalacsonyabb írási- és olvasási sebességgel rendelkezni. M.2 drive length isn't always an indicator of drive capacity, but therearelimits to NAND-chip density and how many memory modules engineers can stuff onto a PCB of a given size. As a result, most of the M.2 drives we've seen to date have topped out at 2TB, though you can find a few 4TB and 8TB models at lofty prices. The typical capacity waypoints are as follows: The T700 is for gamers, creatives, and professionals seeking the ultimate in solid-state drive performance that today only a Gen 5 SSD offers. But unless your desktop is a recent, high-performance model that supports this standard, being able to run a PCI Express 5.0 SSD at peak speeds requires a considerable additional investment. You must buy a recent desktop that supports SSDs built on the PCIe 5.0 standard, upgrade an existing recent rig, or build one from scratch. By making such an investment and having the T700 serve as its brains, though, you're future-proofing your entire setup. Performance is good, as would be expected from a drive with InnoGrit’s IG5220 controller and Micron’s 176-layer TLC flash. While DRAM-less and not as fast as high-end PCIe 4.0 drives, this combination remains competitive and more than enough for most users. However, the aesthetics come at a price: the Viper VPR400 is very expensive for what it is. This is therefore a drive for the gamer who is willing to pay more for the perfect thematic build.
