Western Digital WD_BLACK SN770 1TB PCIe 4.0 x4 NVMe M.2 2280

The WD_BLACK SN770 is a 1TB PCIe 4.0 NVMe SSD that delivers excellent gaming and boot drive performance at a competitive price. It's DRAM-less but still hits 5,150 MB/s reads and strong random IOPS, making it a great value pick. Just make sure you're not paying more than USD 200 for it.

Sequential reads hit 5,150 MB/s and writes land at 4,900 MB/s in our database. That's not the absolute fastest Gen4 drive out there, but it's well above average for the category. Random performance is where this drive actually shines: 740K random read IOPS and 800K random write IOPS put it in the 91st percentile for random workloads. That means snappy app launches, quick file access, and less waiting around when Windows decides to do fifty things at once.

The DRAM-less design doesn't hurt as much as you'd think. WD uses HMB (Host Memory Buffer) to borrow a slice of your system RAM for the mapping table, and for gaming and everyday use, you won't feel the difference. Where you might notice it is sustained heavy writes, like moving hundreds of gigabytes in one go. But for a gaming drive or boot drive, this thing is quick and consistent.

Stacked against the Samsung 990 PRO, the SN770 loses on raw speed. The 990 PRO pushes past 7,000 MB/s reads, but you'll pay a premium for that headroom. If you're moving massive files daily, the 990 PRO or Crucial T500 make more sense. The T500 is probably the closest competitor in terms of price and performance, with slightly better sustained writes thanks to its DRAM cache.

The Kingston Fury Renegade is another Gen4 option that trades blows with the SN770, often at a similar price. The Team Group MP44 is the budget alternative, usually cheaper but with lower endurance and less consistent performance. For gaming and general use, the SN770 holds its own against all of them. For heavy workstation workloads, the DRAM-less design starts to show its limits.

At USD 175, this drive is an absolute no-brainer. At USD 270, you're getting into Samsung 990 PRO territory and should probably just buy that instead. The spread between vendors is USD 95, which is ridiculous for the same product. Newegg and Amazon both list it, but you'll want to check both before pulling the trigger. Compared to the Crucial T500 or Kingston Fury Renegade, the SN770 often undercuts them on price while delivering 90% of the real-world performance. For most people, that's the better deal.

The WD_BLACK SN770 is a 1TB M.2 NVMe SSD that sits in that sweet spot between budget drives and flagship screamers. It's a PCIe 4.0 drive with a DRAM-less design, which sounds like a compromise on paper, but Western Digital's controller and TLC NAND do a lot of heavy lifting here. You're looking at 5,150 MB/s reads and 4,900 MB/s writes, which puts it well ahead of any PCIe 3.0 drive and close enough to the top-tier Gen4 stuff that most people won't notice the difference.

Is the WD_BLACK SN770 good for gaming? Yeah, it's built for it. Load times drop hard compared to older SATA or Gen3 drives, and it supports DirectStorage for future titles. It's also a solid pick for a Windows 11 boot drive, which is exactly how a lot of buyers are using it. The 600 TBW endurance rating and 5-year warranty mean you're not gambling on longevity either.

Price-wise, this thing bounces around a lot. We're seeing USD 175 to USD 270 across vendors, which is a wild spread for the same drive. At the low end it's a steal. At the high end, you're paying too much and should shop around.

Skip this drive if you're doing heavy sustained write workloads like 4K video editing or constant large file transfers. The DRAM-less design will show its limits there, and you'd be better off with a Crucial T500 or Samsung 990 PRO. Also skip it if you're on a PCIe 3.0 motherboard and don't plan to upgrade soon. You'll still see gains over SATA, but you're paying for Gen4 speeds you can't use. And if you see it priced above USD 200, wait for a sale or look at the Team Group MP44 instead.

Should you buy the WD_BLACK SN770? If you're building a gaming PC or upgrading an older system and want fast load times without spending flagship money, yes. This drive nails the fundamentals: fast enough for anything you'll throw at it, reliable enough to trust as a boot drive, and priced right when you catch it on sale.

But don't overpay. The USD 175 to USD 270 spread means you need to shop around. And if you're on a PCIe 3.0 motherboard, you'll still see a nice upgrade over SATA, but you're leaving performance on the table. For most gamers and everyday users, this is one of the best value Gen4 drives on the market right now.
