Fikwot FN990 4TB PCIe 4.0 x4 NVMe M.2 2280

The Fikwot FN990 4TB hits 7350 MB/s read and carries an 8000 TBW endurance rating, good for the 98th percentile. That's the good news. The bad news is a DRAM-less design that leaves random performance at a middling 62nd percentile, and a price that lands in the 15th percentile for affordability.

Sequential speeds are the headline here. 7350 MB/s read and 6250 MB/s write put this drive in the 86th percentile for speed, which means it's one of the better performers on the market. For PCIe 4.0, that's essentially maxing out the interface. Game loads and large file transfers will feel snappy.

The random performance tells a more modest story at the 62nd percentile. That's about average, and it's where the DRAM-less design shows its limits. HMB helps, but it's not a replacement for a dedicated DRAM cache when you're hammering the drive with small random reads and writes. For gaming and general use, you probably won't notice. For heavy workstation workloads, you might.

Against the Samsung 9100 PRO, the Fikwot holds its own on sequential speed but gives up ground on random performance and brand trust. The Kingston FURY Renegade 4TB is a closer fight, with similar PCIe 4.0 speeds and a DRAM cache that the FN990 lacks. The Crucial T500 and WD_BLACK drives both bring stronger all-around performance and better social proof, though they may not match the 8000 TBW endurance. The Micron T710 is another solid alternative if you want enterprise-grade reliability without the RGB flair. The FN990's endurance is its differentiator, but the DRAM-less design keeps it from being the clear winner in this group.

At $550 USD, this drive is not winning any affordability awards. The 15th percentile ranking means it's priced near the bottom of the value barrel. You're paying a premium for the 4TB capacity and that 8000 TBW endurance. The CAD listing at $821 and EUR listings around 603 to 624 don't soften the blow either. If you need a drive that will outlive everything else in your system, the endurance might justify it. If you just want fast storage, there are cheaper ways to get similar speeds.

The Fikwot FN990 4TB hits 7350 MB/s read and 6250 MB/s write, which puts it in the 86th percentile for speed in our database. That's fast enough to hang with drives costing a lot more, and the 8000 TBW endurance rating is genuinely impressive, landing at the 98th percentile. You're getting a drive that should outlive several PC builds.

But there's a catch. This is a DRAM-less design leaning on HMB, and the random performance sits at the 62nd percentile, which is solid but not spectacular. The RGB heatsink is a nice touch if you're into that sort of thing, and the 4TB capacity at 93rd percentile means you won't be juggling game installs anytime soon.

Skip this if you're on a budget. The affordability ranking at the 15th percentile means you're paying a serious premium for that endurance and capacity. Also skip it if you do heavy workstation tasks with lots of small random reads and writes, the DRAM-less design and 62nd percentile random performance will hold you back. And if you need something portable, the 20.8 out of 100 portable score makes this a terrible choice for external enclosures.

The Fikwot FN990 4TB is a drive with a split personality. The sequential speeds and endurance are genuinely impressive, with the 8000 TBW rating putting it in the 98th percentile. But the DRAM-less design and mediocre random performance keep it from being a no-brainer. If you want a high-capacity drive that will last forever and you don't mind paying for it, this is a solid pick. If you're chasing the best all-around performance, the competition offers more balance for similar money.
