Pros & Cons
Pros
- Blazing fast 7450 MB/s reads for the price 93rd
- Excellent random performance, top 7% of all drives 90th
- Graphene thermal pad keeps temps in check 88th
- 5-year warranty and 1.5M hour MTBF 87th

What owners think
The Word on the Street
The proof
Performance
What surprised us most is how well this DRAM-less design holds up. The 1000K random read IOPS and 900K random write IOPS are genuinely impressive, landing in the 93rd percentile for random performance. That's the kind of number you'd expect from a drive costing twice as much. Sequential speeds are no slouch either, sitting at the 90th percentile. The HMB tech clearly does its job, keeping things snappy even without onboard DRAM.

vs Competition
Against the Samsung 990 PRO, the NV7400 gives up some endurance and sustained write performance, but it's significantly cheaper. The Crucial T500 is probably the closest competitor in terms of value, but the BIWIN edges it out on random performance. The WD BLACK SN850X is still the king for pure gaming, but you'll pay a premium for that crown. If you're on a budget, the NV7400 is the smart pick.

Overview
The BIWIN Black Opal NV7400 is one of those drives that makes you wonder why you'd pay more for a Samsung. It's a DRAM-less PCIe 4.0 NVMe that still manages to hit 7450 MB/s reads and 6500 MB/s writes, which puts it right up there with the best Gen4 drives on the market. The one thing to know? This is a budget-friendly speed demon that punches way above its weight class.
Common Questions
Q: Is this drive good for PS5?
Yes, it works great. The 7450 MB/s read speed exceeds Sony's 5500 MB/s minimum requirement, and the graphene heatsink helps with thermals. Just make sure you get the version with the heatsink pre-installed.
Q: Does DRAM-less matter for gaming?
Not really. For gaming and everyday use, the HMB technology compensates well. You'd only notice a difference in heavy sustained write workloads like video editing or large file transfers.
Q: How does this compare to the Samsung 990 PRO?
The Samsung has better endurance and slightly better sustained performance, but the NV7400 is much cheaper. For most people, the BIWIN is the smarter buy.
Who Should Skip This
If you're doing heavy video editing or running a server with constant write loads, this isn't your drive. The endurance rating is bottom 15%, and the DRAM-less design will choke on sustained writes. Go get a Samsung 990 PRO or WD BLACK SN850X instead. And if you need something portable, forget it, this scored a pathetic 19.8 out of 100 for portability.
Verdict
Buy it. The BIWIN Black Opal NV7400 delivers 90% of flagship performance at 60% of the price. The endurance concerns are real, but for most users, this drive will outlast the rest of your system. It's the drive I'd recommend to anyone building a gaming PC or upgrading a PS5 on a budget.
