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

The NV7400 hits 7450 MB/s read and 1000K random read IOPS, landing in the 90th and 93rd percentiles respectively. That's near-flagship PCIe 4.0 performance with TLC NAND and a single-sided design that fits in a PS5. The catch is endurance at the 15th percentile and a price that's above average, so it's a performance pick, not a budget one.

The headline numbers are 7450 MB/s sequential read and 6500 MB/s sequential write. That read speed is top-tier for PCIe 4.0, and the random performance is even more impressive relative to the field. 1000K random read IOPS and 900K random write IOPS put this drive in the 93rd percentile for random performance, which is a standout result. For game loading, OS boots, and general snappiness, random IOPS matter more than sequential speeds, and this drive delivers.

The DRAM-less design relies on Host Memory Buffer (HMB) technology, which borrows a slice of your system RAM to handle the mapping tables. In practice, that works fine for gaming and everyday use, though sustained heavy writes can dip more than a DRAM-equipped drive. The graphene aluminum heatsink keeps temperatures low, and multiple owners mention the drive running cool even under load. The TLC NAND is a plus at this price point, since some budget drives cut corners with QLC.

Against the Western Digital Black SN850X, the NV7400 matches or beats it on sequential read speed but gives up ground on endurance and brand trust. The SN850X has a longer track record and better endurance ratings, though it typically costs more. The Samsung 9100 PRO is a PCIe 5.0 drive, so it's in a different performance class entirely, but several owners say the NV7400 feels close in real-world use, which is high praise for a PCIe 4.0 drive. The Crucial T500 is probably the closest competitor on paper, with similar speeds and TLC NAND, but Crucial has better brand recognition and wider availability. The Kingston FURY Renegade G5 is another strong option with DRAM onboard, which gives it an edge in sustained write workloads. The NV7400's random performance is its ace, and that's where it beats most of these competitors in our database.

The value story here is complicated. The affordability percentile is 28th, which means this drive is priced above most of its peers. The US listing shows $341 for the 2TB model, and the Canadian listing is CAD 480. That's not cheap for a DRAM-less PCIe 4.0 drive. But users keep saying it's good value for money, and the sentiment data backs that up with six positive mentions of value. The math works out because you're getting near-flagship random performance and TLC NAND without paying Samsung or WD flagship prices. It's not a budget drive, but it's a performance drive at a mid-tier price.

The BIWIN Black Opal NV7400 hits 7450 MB/s read and 6500 MB/s write, which puts it in the 90th percentile for speed in our database. That's PCIe 4.0 territory that flirts with what we used to call flagship numbers just a couple years ago. The 2TB capacity lands at the 78th percentile, so you're getting a serious chunk of storage without jumping to a 4TB price tag. And it's DRAM-less, which is the trade-off that keeps the cost down but also explains some of the endurance numbers we'll get into.

Users seem genuinely happy with this thing. The sentiment score sits at 92 out of 100 across 638 reviews, and the recurring themes are speed, value, and easy installation. PS5 owners especially like it as a storage expansion. The brand isn't a household name like Samsung or WD, and that shows up in the social proof percentile at 77th. But the actual experience people report is solid, and the numbers back it up where it counts.

If you're planning to write massive amounts of data constantly, like video editing or running a database, the 15th percentile endurance should give you pause. This drive isn't built for heavy sustained write workloads. Budget shoppers should also look elsewhere, since the 28th percentile affordability means you're paying a premium for the speed. And if you want a drive from a brand with a long track record and easy warranty support, Samsung or WD are safer bets.

The BIWIN Black Opal NV7400 is a fast drive with a few asterisks. The 93rd percentile random performance and 90th percentile speed are genuinely impressive, and the TLC NAND plus single-sided design make it a solid pick for PS5 owners and laptop users. But the 15th percentile endurance is a concern if you're planning to hammer this drive with constant writes, and the 28th percentile affordability means you're not getting a bargain. If you want top-tier random performance and don't mind a lesser-known brand, this is a strong choice. If endurance or brand trust matter more, look at the SN850X or T500.
