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

The BIWIN Black Opal NV7400 is a 4TB PCIe 4.0 drive with 7450 MB/s reads and top-tier random performance. It's a great PS5 or gaming PC upgrade, especially with the included heatsink and single-sided design. Endurance is weak and the brand is unknown, but real users love it and the value is there.

Sequential reads hit 7450 MB/s and writes land at 6500 MB/s, which is right at the ceiling for PCIe 4.0. Random performance is a standout too, 1000K read IOPS and 900K write IOPS put it in the 93rd percentile. That's one of the best random access results we've seen on a Gen4 drive. The DRAM-less design doesn't seem to hurt much here, thanks to HMB support on modern platforms. But endurance is a weak spot, 15th percentile is rough. If you're hammering this drive with constant writes, the lack of DRAM and lower endurance rating will catch up with you eventually. For gaming and everyday use, you'll never notice.

The NV7400 goes head to head with the WD Black SN850X and Crucial T500, and it holds its own on raw speed. The SN850X has DRAM and better endurance, so it's the safer pick for heavy workloads. The T500 is a bit cheaper and also has DRAM, but the BIWIN matches it on sequential reads and beats it on random IOPS. The Kingston FURY Renegade G5 is another strong Gen4 option with similar specs. Where the BIWIN stands out is the 4TB single-sided design and included heatsink, which makes it a drop-in PS5 upgrade. But if you're building a workstation that sees constant writes, the Samsung 9100 PRO or SN850X are better long-term bets.

We don't have a price on this exact 4TB model, but the sentiment data keeps pointing to good value for money. Users mention it rivals pricier PCIe 5.0 drives in real-world use, which is high praise. The 1TB version gets dinged for being a bit expensive, but at 4TB you're getting a lot of fast storage. If the price lands anywhere near the competition from Crucial or Kingston, this is a solid deal. Just don't expect the endurance of a workstation drive.

The BIWIN Black Opal NV7400 is a 4TB PCIe 4.0 drive that hits 7450 MB/s reads and 6500 MB/s writes. That's basically maxing out the Gen4 interface, and it lands in the 90th percentile for speed in our database. It's DRAM-less, which usually makes us nervous, but the TLC NAND and a solid controller keep it feeling snappy in real-world use.

BIWIN isn't a household name like Samsung or WD, and that shows in the social proof numbers. But the people who actually bought this thing seem genuinely happy. A 4.6-star average across 637 reviews is nothing to sneeze at, and the sentiment score sits at 88/100. The drive works great in a PS5 or a gaming rig, and the included heatsink is a nice touch.

Skip this if you're doing heavy video editing, running a database, or anything that hammers the drive with constant writes. The endurance rating is one of the worst we've seen in this class, and the DRAM-less design will show its limits under sustained load. If you need a workhorse, spend the extra cash on a WD Black SN850X or Samsung 9100 PRO.

This is a gaming and console drive first, and it nails that job. The speed is top-tier for Gen4, the 4TB capacity is generous, and the single-sided design means it fits in a PS5 without drama. Power users who need sustained write performance or high endurance should look elsewhere. But for most people who just want a fast, big SSD that works, the NV7400 is a surprisingly good pick from a brand you've probably never heard of.
