Samsung 970 EVO Plus 1 TB PCIe NVMe M.2 Internal Solid State Drive (SSD) (MMZ-V7S1T0BW )

Product Information

Definition of capacity: KIOXIA defines a megabyte (MB) as 1,000,000 bytes, a gigabyte (GB) as 1,000,000,000 bytes and a terabyte (TB) as 1,000,000,000,000 bytes. A computer operating system, however, reports storage capacity using powers of 2 for the definition of 1GB = 2 This isn't a slow SSD, either. It's right up there with the very best PCIe Gen4 drives today at 7,400MB/s read and 6,500MB/s write. In our own testing, we measured it at 7,106MB/s seq. read and 6,504MB/s seq. Write—very nearly bang on what's advertised, which is really great. The AHCI (Advanced Host Controller Interface) command protocol was designed for much slower media (i.e., spinning magnetic disks). AHCI is inefficient with modern SSDs, so a new standard was developed: NVMHCI (Non-Volatile Memory Host Controller Interface). Combine NVMHCI with a fast PCIe interface, and you have NVMe, Non-Volatile Memory Express. It's a much-improved interface developed around the needs of flash memory rather than spinning disks. What's NVMe performance like in the real world? The point is, there's not much this Lexar drive can't do, and for a good price. If you have a spare Gen4 slot in your machine, and you are desperate for more game storage space, I highly recommend you look to the Lexar NM790 to fill that slot. 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.

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. The XS70 is designed with PS5 compatibility in mind so the heatsink isn’t as bulky as some others you might come across. It really does look good. Admittedly I'm talking about an SSD here, and its not the kind of thing you'll spend time looking at, but Silicon Power's designers deserve credit. 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. For one, this drive is cool under load. When transferring over 200GB of data in one steady stream, which you may not do all that often in real-world use, we measured the temperature at 72°C. That's an admirable temperature from a drive with no active cooling solution and high speeds.

Average Power Consumption (system level) *Average: 6.2 W *Maximum: 8.9 W (Burst mode) * Actual power consumption may vary depending on system hardware & configuration 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.

Compatible with PCI Express ® Base Specification Revision 3.1a and NVM Express™ Revision 1.3c command set We put every SSD we get in the PC Gamer labs through their paces in various benchmarks made up of a mix of synthetic tests and real-world applications. To ascertain a drives sequential throughput, we use ATTO SSD Benchmark for compressible data (a best-case scenario) and AS SSD for incompressible data (more realistic). We also test random throughput with AS SSD and a combination of CrystalDiskMark 7.0 and Anvil Pro.

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. 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. It's worth noting that this drive can get hot when pushed, just like the SN850. It hit 76°C after a long day of testing, but without direct cooling on it, not even a heatsink. It should be fine in most systems, especially if your motherboard does come with some cooling solution.For most PC applications, that probably doesn't matter. But for small form factor rigs and perhaps a gaming laptop, every little can undoubtedly help. On that note, for most applications, we'd probably go for the cheaper bare drive rather than this more expensive model with its heat spreader. The revised SN850X is inherently a cooler-running thing, after all.
