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

The NV7400 hits 7450 MB/s reads and 1000K random IOPS, putting it at 90th and 93rd percentile respectively. Owners rate it 4.6 stars across 638 reviews, with sentiment at 95th percentile. The catch is endurance at 15th percentile and a price that lands at 27th percentile for affordability.

Let's talk numbers. The NV7400's 7450 MB/s read speed is essentially maxing out what PCIe 4.0 can do. That's the same ballpark as drives like the WD Black SN850X and Crucial T500, and owners report it feels close to PCIe 5.0 territory in real-world use. The random performance is where this thing really shines though. 1000K read IOPS and 900K write IOPS put it at 93rd percentile in our database, which is a standout result for a DRAM-less drive. HMB is doing some heavy lifting here, and it's working.

The TLC NAND and Smart Cache keep sustained writes from falling off a cliff, though the endurance numbers suggest you shouldn't expect marathon-level longevity. The graphene heatsink does its job too, with multiple owners noting low operating temperatures even under load. For gaming, it scores 73.1 out of 100, and for console use it's even better at 76.4. The portable score of 20 out of 100 is the obvious weak spot, but that's not really what this drive is built for.

Against the WD Black SN850X, the NV7400 matches it on sequential reads but edges ahead on random IOPS. The SN850X has better endurance numbers and a more established track record, but it also typically costs more. The Crucial T500 is the closest competitor on paper, with similar speed ratings and TLC NAND, but the BIWIN's user sentiment score of 95th percentile actually beats what we typically see for Crucial drives. The Samsung 9100 PRO is a PCIe 5.0 drive, so it'll outpace this on raw bandwidth, but owners say the NV7400 feels close enough in everyday use that the price difference is hard to justify. The Kingston FURY Renegade G5 and Seagate FireCuda 530R are both solid alternatives, but neither matches the NV7400's random IOPS at this price point.

At $341 USD for the 2TB model, you're paying roughly $170 per terabyte. That's not cheap, and the 27th percentile affordability ranking confirms it. The 1TB version gets called out by owners as particularly pricey. But here's the counterpoint: you're getting top-tier PCIe 4.0 speed with random performance that beats many more expensive drives. The CAD listing at $480 is the only other price we're seeing, so availability is thin. If you can find this on sale, the value proposition improves dramatically. At full price, you're paying a premium for speed and a heatsink, not for brand cachet.

The BIWIN Black Opal NV7400 hits 7450 MB/s sequential reads and 6500 MB/s writes, which puts it in the top tier of PCIe 4.0 drives in our database. That's 90th percentile speed territory, and the random performance is even better at 1000K read IOPS and 900K write IOPS, landing at 93rd percentile. For a DRAM-less drive using HMB, those are seriously impressive numbers. The 2TB capacity gives you room to breathe, and the single-sided design with the graphene heatsink means it'll drop into a PS5 or thin laptop without a fuss.

But here's the thing. The endurance score sits at 15th percentile, which is a real weak spot. And while the user sentiment is glowing at 95th percentile with a 4.6 star average across 638 reviews, the affordability ranking is rough at 27th percentile. You're paying a premium for this speed, and the brand doesn't have the name recognition of Samsung or WD yet. Still, owners seem genuinely happy with what they're getting.

If you're planning to write terabytes of data constantly, this drive's 15th percentile endurance score should give you pause. Content creators doing daily 4K video exports, database workloads, or anyone who wants a drive to last 7 to 10 years under heavy use should look at something with better endurance ratings. The DRAM-less design also means sustained write performance will dip more than a drive with dedicated DRAM cache. And if you're on a tight budget, the 27th percentile affordability ranking means you can find 2TB PCIe 4.0 drives for less, just with slightly lower peak speeds.

The BIWIN Black Opal NV7400 is a genuinely fast drive that owners love. A 4.6 star average from 638 reviews and 95th percentile user sentiment don't lie. The speed is real, the thermals are good, and the PS5 compatibility is a nice bonus. But the 15th percentile endurance score is a nagging concern, and the price isn't doing you any favors at 27th percentile affordability. If you want maximum speed per dollar and don't mind a less proven brand, this is a strong pick. If you're planning to hammer the drive with constant writes or want a decade of heavy use, look elsewhere.
