In many other regards, this X model is a dead ringer for the SN850. We’re talking four lanes of PCIe Gen 4 connectivity in the now ubiquitous M.2 2280 form factor. But the 1TB model reviewed here is now the entry-level option. There’s no longer a 512GB model. What’s more, WD’s in-house controller chip, provided by compatriot SanDisk, has been revised, though detailed specifics aren't provided. Crucial's T700 is the world's fastest SSD, taking the hands-down performance lead in every performance category. That groundbreaking speed comes courtesy of the drive's PCIe 5.0 x4 connection, which offers a pathway for up to twice the throughput of PCIe 4.0 SSDs, and the Phison E26 SSD controller paired with Micron's leading-edge 232-Layer 3D TLC flash. That potent common creates an SSD that's the fastest on the market for PC game loading times. Thedata bus, or pathway, over which your data travels to and from an M.2 drive is a whole other matter, which is where PCI Express and NVMe come in. We'll get to the significance of NVMe in a moment; first, let's discuss the key physical traits of an M.2 drive that you need to understand. (The video below is a good primer.) Silicon Power is a brand that probably doesn’t get much attention compared to the likes of Samsung or WD, but when you look at its XS70 NVMe SSD with its high-end specifications, it's clear that the brand name isn't everything. Armed with the latest Phison controller and high-performance NAND flash memory, a drive like the Silicon Power XS70 should have no problem competing with thebest SSD on the market. We've already mentioned one you know—SSD. It stands for "solid-state drive," a storage drive made up of flash memory in modules called NANDs and governed by a controller chip. (The name NAND comes from a type of logic gate in Boolean algebra; we'll try to explain terms as we go along, but if you need a refresher in SSD lingo see our rundown of 20 terms you need to know.) Unfortunately, SSD shopping has been complicated in recent years by the emergence of three new technologies: M.2, PCI Express (abbreviated PCIe), and NVMe. All three are centered around making SSDs smaller or faster. They also make buying a solid-state drive more challenging than ever.

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 Well, it's got it all if the context is PCIe 4.0 drives. There is a new generation of PCIe 5.0 drives but they're a bit over the top for most gamers right now. PCIe Gen 4 is not only where it's at, it's probably also the limit of your PC or laptop's capabilities. You can use these PCIe 4.0-based SSDs in PCIe 3.0-only systems, but they'll just dial down to PCIe 3.0 speeds. So should you opt for one? If you'll be assembling or upgrading a late-model AMD or Intel PC with the right chipset, by all means. Hardcore gamers and content creators working on today's newer PCs will stand to gain the most. If you have a PCIe 4.0-capable slot for one, get one; otherwise, 3.0 will likely do you fine. 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.In my early career, I worked as an editor of scholarly science books, and as an editor of "Dummies"-style computer guidebooks for Brady Books (now, BradyGames). I'm a lifetime New Yorker, a graduate of New York University's journalism program, and a member of Phi Beta Kappa. The synthetic performance shows the SN770 trails more expensive drives in terms of reads, although the writes are much closer. The 4K performance is relatively impressive and shows that the SN770 has something to offer in this crowded marketplace. It's not too surprising that this drive outperforms Samsung's DRAM-less offering, as that is a PCIe 3.0 drive, after all, but the extent to which it does is impressive. It's a highly competitive SSD with great performance and an attractive design and offers good value for money. Reduced operating temps are another clear benefit of this new drive. The old SN850 hit a toasty 77°C. The new drive hits just 58°C under sustained load. That's a very worthwhile improvement. Elsewhere, the gains are less obvious, albeit the SN850 was already a great drive. The 4K random access results are a little disappointing, showing little to no improvement. Likewise, don't expect big gains in system-wide measures of performance like PCMark 10. Give it up for the new SK Hynix Platinum P41 2TB. If that doesn't exactly roll off the tongue, it also doesn't help that SK Hynix isn't the most familiar brand regarding the sort of consumer-focused clobber that's aimed at gamers, including SSDs.

The PCIe 5.0 SSDs still have plenty to offer. The Crucial T700 is unquestionably the fastest consumer SSD in the world that you can actually buy, at least for now, delivering up to a blistering 12.4 GB/s of sequential throughput and 1.5 million random IOPS over the PCIe 5.0 interface. That's an amazing level of performance from an amazingly compact device. The Team MP44 is part of the vanguard for new and better DRAM-less SSDs. Newer controllers and flash are letting budget/value drives push the limits of the PCIe 4.0 interface while providing high capacities without making compromises. They can have the endurance and performance of TLC and the high power efficiency of four-channel, DRAM-less controllers, all without extra cost. Less power means less heat, and these drives are also designed to be single-sided. That combination makes the MP44 perfect for laptops.In practice, all of today's PC builder- or upgrader-minded M.2 drives and slots are 22mm wide, so you can expect this number to start with 22. The most common lengths are 80mm (M.2 Type-2280) and 60mm (M.2 Type-2260). Drives as short as 30mm (M.2 Type-2230) or as long as 110mm (M.2 Type-22110) do exist, however. Why the differences in length? The longer the drive's PCB (printed circuit board), the more surface area it has to hold memory chips. 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.

Welcome to the cutting edge! You're shopping for a kind of drive that many folks don't even realize exists. As a result, you need to pay attention to several factors that may not be documented very well while you shop. Let's recap.
HP FX900 PCIe 4.0 M.2 SSD
It's in the real-world tests where the SN770 really struts its stuff. You'd be hard-pushed to tell the difference between this drive and much faster offerings in most day-to-day operations. Given this is the cheaper drive right now, that counts for a lot. The SN850 is the better drive if you need better performance, but you will pay considerably more. The main way it achieves this is by being a DRAM-less SSD drive. This saves a big chunk of the manufacturer's bill of materials, and thanks to advances in the latest controllers, it can be surprising how little impact this has on performance. Such drives are slower, don't get me wrong, but this new SN770 still quotes read and writes of 5,150MB/s and 4,900MB/s, respectively. Not bad. Of course, to show off the lighting, you will need to have an open-frame rig, or one with a see-through case. If you've already RGB'd your keyboard, mouse, video card, motherboard, case, and headphones, and are at a loss for what's left, the Spectrix S40G makes enough sense both in performance and looks to belong in any lighting-obsessed custom PC builder's arsenal.
