Samsung 970 EVO Plus SSD 2TB - M.2 NVMe Interface Internal Solid State Drive with V-NAND Technology (MZ-V7S2T0B/AM)

Product Information

Samsung's 990 Pro M.2 SSD garnered attention upon its announcement, primarily due to its adherence to the existing PCIe 4.0 standard instead of the anticipated PCIe 5.0. However, its performance, nearly maxing out the PCIe 4.0’s potential, silenced many naysayers. For gamers, it boasts unparalleled read speeds; for creative professionals, its write speeds shine, especially during intensive tasks. The Lexar does differ from many others we've looked at. We've come to expect higher-end Gen4 drives to rely on Phison's very popular E18 controller, but the Lexar doesn't. It uses a MaxioTech MAP1602A controller, a less known quantity in the US and EU markets. This makes for overtly different behaviour in testing to more common controllers, but not in a bad way. 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 Crucial T500 is for users willing to pay a little extra to get the best PCI Express 4.0 SSD performance. At a time when many low-priced DRAM-less SSDs are hitting the market, the T500 has a full DRAM cache (as well as a top-shelf Phison controller and 232-layer TLC NAND flash), which could give it an advantage in sustained large-file transfers, as well as in use with the PS5. Of course, SK Hynix isn't new to this space, but the new P41 is arguably the brand's first tilt at a truly high-end M.2 drive. The old SK Hynix Gold P31 was a bit of a clunky old thing, limited as it was to the PCIe 3.0 interface and a controller chip with a mere four memory channels. The new Platinum P41? It's got it all.

A standout feature: the 990 Pro's sequential writes significantly outpace both its predecessor and competitors. Additionally, it showcases impressive read speeds, nearing PCIe 4.0's maximum of 8,000MB/s.That's not a bad thing. Especially in the case of laptops, an older machine might supportonlyM.2 SATA-bus SSDs, and that will be the boundary of your upgrade path...end of story. As a result, the only reasons you'd upgrade the drive, in that situation, would be to get more capacity, or if the old one failed. 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.

South Korean memory-chip maker SK Hynix is a relative newcomer to the consumer solid-state drive market, but you would never know that based on its first offerings. The SK Hynix Platinum P41, a PCI Express 4.0 NVMe M.2 SSD, is its best yet. It dominated our PCMark 10 and 3DMark Storage benchmark testing, setting several new records in the process. The P41 supports 256-bit AES hardware-based encryption. SK Hynix provides a clone utility tool, the SK Hynix System Migration Utility, for its SSDs, in addition to Easy Drive Manager software, which lets you see detailed information on drive health, run diagnostics, and erase the drive. And the P41 can be had for a very reasonable price in its 1TB and 2TB capacities. Who It's For 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.

Intel for a while sold a family of M.2-based storage products under the brand name Optane, in two very distinct types of drive. Intel's "Optane SSDs" were SSDs like any other, bootable drives that can serve as a stand-alone boot drive or as secondary storage. They were discontinued for consumers in 2021, but you may still see them around. (Intel sold its SSD business at the end of 2021 to SK Hynix, which spun it off into a new subsidiary, Solidigm.) All of this leaves the minor matter of how this drive actually performs. When it comes to peak sequential throughput, the Platinum P41 is basically as fast as anything else out there, bar a few rounding errors. OK, the Samsung 990 Pro is a bit faster at 7,462MB/s for reads to the P41's 7,375MB/s. But, honestly, it's inconsequential. The same goes for writes, where almost all the top drives will do just under 6.9GB/s.

Running on the same basic interface as your graphics card, NVMe SSDs deliver more raw bandwidth and performance than any SATA-based SSD could ever offer. They're also a lot smaller than any other hard drive or SSD too, which all means that the best NVMe SSDs are perfect for either that small form factor build you always wanted or a monstrous high-end gaming PC build. What PCIe generation should I look for? While PCIe 4.0 SSDs have a theoretical maximum speed of 8,000MB/s, the PNY XLR8 CS3140 pushes right up to that line with a rated sequential read speed of 7,500MB/s, along with a 6,850MB/s sequential write rating for its 2TB and 4TB capacities (5,650MB/s for 1TB).

Lexar NM790

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. 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. Finally, on the speeds and feeds, this 2TB drive is rated at 1,200TB for write endurance. As it happens, that's precisely the same as the new Samsung 990 Pro 2TB. But it's also far from some other competing M.2 SSDs. 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. (Credit: Molly Flores)

It improves game loading times courtesy of a so-called "read look-ahead" algorithm, which predictively caches game data.

So, What Is the Best M.2 SSD to Buy?

We actually like these because often, you often get a robust heat sink on the M.2 drive. Some PCI Express-bus M.2 SSDs can run hot under sustained read/write tasks and throttle their speed. That said, unless you're running a server or something similar, where a drive is constantly getting hammered with reads and writes, that's usually not something you have to worry about. That's because many of these drives are so fast, they get their transfer duties done before they have a chance to get all that hot.
