BIWIN NV7400 4TB PCIe 4.0 x4 NVMe M.2 2280

The BIWIN Black Opal NV7400 is a fast 4TB Gen4 drive with top-tier random performance and a PS5-friendly design. Endurance is weak and the brand is lesser-known, but users love the speed and value. Worth buying if you find it on sale and don't need enterprise-grade endurance.

Sequential speeds are the headline here, and they're legit. 7450 MB/s read and 6500 MB/s write put this drive in the 90th percentile for speed, which means it's one of the best Gen4 drives on the market. Random performance is even better, landing in the 93rd percentile with 1000K read IOPS and 900K write IOPS. That's the kind of responsiveness you feel when loading games or scrubbing through large video files. The DRAM-less design doesn't hurt as much as you'd expect thanks to NVMe 2.0 and good firmware, but endurance is the ugly side of this coin. It sits in the 15th percentile, which is disappointing for a 4TB drive. If you're writing terabytes of data every week, this isn't your drive.

Against the Western Digital Black SN850X, the NV7400 matches it on sequential reads but falls behind on endurance and brand trust. The Samsung 9100 PRO is a PCIe 5.0 drive that smokes this in raw speed, but you'll pay a lot more for it. The Kingston FURY Renegade G5 and Crucial T500 are closer competitors, with the T500 offering better endurance and a more established track record. The SanDisk WD_BLACK SN8100 is basically the same drive as the SN850X with a different label. If you want the safest bet, go WD or Crucial. If you want max speed per dollar and don't mind a newer brand, the NV7400 is worth a look.

Value is tricky here. Users consistently say this drive is good value for money, and at 4TB with these speeds, it's hard to argue. But the affordability percentile is dead last, which means it's priced higher than almost everything else in its category. The 1TB version gets called out specifically as overpriced. If you can find the 4TB model at a discount, it's a solid deal. At full retail, you're paying a premium for a brand that hasn't earned the same trust as WD or Samsung.

The BIWIN Black Opal NV7400 is a 4TB PCIe 4.0 drive that hits 7450 MB/s reads and 6500 MB/s writes. That puts it in the top tier of Gen4 drives in our database, right up there with drives that cost a lot more. It's DRAM-less, which usually makes us nervous, but the TLC NAND and smart thermal design keep it from falling on its face.

BIWIN isn't a household name, and that's the main thing holding this drive back. The specs are legit, the user sentiment is strong, and it works great in a PS5 or gaming rig. But you're buying from a lesser-known brand, and the endurance numbers are a real weak spot.

Skip this if you do heavy content creation, run databases, or write hundreds of gigabytes daily. The endurance rating is one of the worst we've seen in this class, and the DRAM-less design will choke on sustained writes. Also skip it if you want established brand support and bundled software, because BIWIN offers neither.

This drive is for gamers and PS5 owners who want a big, fast storage upgrade without paying Samsung or WD prices. The 4TB capacity is the sweet spot, and the single-sided design means it fits in laptops and consoles without clearance issues. Power users who hammer their drives with constant writes should look elsewhere. The endurance rating is a real concern, and the DRAM-less design will show its limits under heavy sustained workloads.
