Samsung 990 1TB PCIe 4.0 x4 NVMe M.2 2280

The Samsung 990 is one of the fastest PCIe 4.0 drives we've tested, with best-in-class random performance and rock-solid reliability. It runs warm and costs more than some rivals, but for most buyers the peace of mind is worth it. If you need speed and stability, this is a top pick.

Sequential reads hit 7,250 MB/s and writes land at 6,450 MB/s, which puts this drive in the top tier of PCIe 4.0 drives we track. Random performance is even more impressive, with 850K read IOPS and 1,200K write IOPS ranking among the best on the market. That translates to fast game loads, snappy file transfers, and smooth 4K video work. The one caveat from real owners is heat. Several report the drive runs warm under sustained load, so if you're cramming it into a tight laptop chassis, a heatsink is worth considering.

The Samsung 990 goes head-to-head with the Western Digital BLACK SN7100 and Crucial T710. The WD drive often undercuts Samsung on price while delivering similar sequential speeds, but Samsung's random write performance is a step above. The Crucial T710 is a strong value pick with better endurance ratings in some capacities. The Micron T710 and Lexar NM1090 PRO are also in the mix, but Samsung's combination of speed, reliability, and brand trust keeps it at the front of the pack for most buyers.

At $190 USD for 1TB, this is not a budget drive. You're paying a premium for Samsung's reliability track record and top-tier random performance. If you're just gaming, a cheaper Gen 4 drive will feel nearly identical in real-world use. But if you're moving large files regularly, running a server, or just want a drive you can forget about for years, the price starts to make sense.

The Samsung 990 is a 1TB PCIe 4.0 NVMe drive that sits near the top of our database for raw speed. It's rated for 7,250 MB/s reads and 6,450 MB/s writes, with DRAM cache and Samsung's in-house controller keeping things snappy. If you're building a new PC or upgrading a laptop, this is one of the easiest recommendations in the category.

But it's not perfect. The endurance rating of 400 TBW is solid but not class-leading, and the 3-year warranty feels a bit stingy for a drive this expensive. Still, the real-world feedback is overwhelmingly positive, with owners praising reliability and stability even under sustained use.

Skip this if you're on a tight budget or only use your PC for gaming. A cheaper Gen 4 drive like the Crucial T710 will feel nearly identical in real-world use. Also skip it if you need maximum endurance for heavy write workloads, since 400 TBW and a 3-year warranty trail some competitors.

Buy this if you want a fast, reliable drive and don't mind paying a bit extra for Samsung's track record. It's ideal for laptop upgrades, new PC builds, and anyone who moves large files regularly. Gamers on a tight budget can save money elsewhere, but if you want a set-it-and-forget-it drive, this is it.
