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

The Samsung 990 PRO is one of the fastest PCIe 4.0 drives around, with 7,450 MB/s reads and top-tier random performance. Update the firmware immediately to avoid a known health degradation issue. If you can find it near USD 140, it's a fantastic buy.

This drive is a monster. Sequential reads at 7,450 MB/s and writes at 6,900 MB/s put it in the 93rd percentile for speed, and the random performance is even better at 97th percentile. That 1,400K random read IOPS figure means it chews through small file operations without breaking a sweat. The in-house controller does a solid job managing thermals too, especially with the heatsink version. For gaming, it's overkill in the best way. For workstation tasks like video editing or large database work, it's one of the best options on the market. The only real performance concern isn't speed, it's the firmware issue that can tank endurance if you don't update.

Against the Crucial T710, the 990 PRO holds its own on speed but the T710 is a PCIe 5.0 drive, so it'll pull ahead in raw throughput if your board supports it. The WD_BLACK SN8100 is a closer match, with similar PCIe 4.0 performance, but the Samsung edges it out on random IOPS. The Corsair MP700 Elite and Lexar NM1090 PRO are also PCIe 5.0 options that beat the 990 PRO on paper. But here's the thing: most people can't tell the difference between 7,000 MB/s and 10,000 MB/s in real-world use. The Samsung wins on consistency and that 5-year warranty, assuming you update the firmware.

Pricing is all over the place. In the US, we're seeing listings from USD 140 to USD 340 for the same drive. That's a huge spread. If you're shopping in Canada, it's CAD 396 to CAD 613. The best US deal in our database is at the lower end of that range, so shop around before you pull the trigger. At USD 140, this drive is an absolute steal. At USD 340, you're paying way too much for PCIe 4.0 when PCIe 5.0 drives are starting to show up. Don't overpay for the Samsung name.

The Samsung 990 PRO is one of the fastest PCIe 4.0 drives you can buy. It hits 7,450 MB/s reads and 6,900 MB/s writes, which is basically maxing out the interface. Samsung's in-house controller and DRAM cache keep things snappy whether you're loading games or moving huge project files.

But there's a catch. Several early batches shipped with firmware that degraded drive health way too fast. Samsung fixed it, but you need to update via Samsung Magician right away. Do that, and you've got a top-tier drive. Skip it, and you might be in for a bad time.

Skip this if you're on a tight budget and don't need bleeding-edge speed. A solid PCIe 3.0 drive will feel nearly identical for everyday tasks and cost a lot less. Also skip it if you're building in a compact case with a motherboard heatsink, the heatsink version won't fit and you can't remove it without risking damage. And if you're the type who never updates firmware, this drive will punish you for it.

If you want a fast, reliable PCIe 4.0 drive and you're willing to spend five minutes updating firmware, the 990 PRO is a no-brainer. Gamers, content creators, and anyone building a high-end rig will love it. Just don't pay full price when the deals are out there.
