Rank #6 in Best 4TB SSD for PS5: 10 Ranked, and the Speed Numbers That Don't Add Up
BIWIN Black Opal NV7400 4TB PCIe Gen4 SSD
Price and rating as shown on Amazon when we collected them. Both change.
Sixth in our guide to 4TB drives for the PS5, the BIWIN Black Opal NV7400 stands out for an unglamorous reason: its numbers agree with each other. The title promises up to 7,450MB/s read. The Read Speed field says 7,450 Megabytes Per Second. The Data Transfer Rate field says 7,450 Megabytes Per Second as well. The first bullet quotes 6,500MB/s write and the Media Speed field returns 6,500 megabytes_per_second. No megabits-for-megabytes slip, no gap between the headline and the spec table underneath it. It also claims M.2 PCIe Gen 4x4, which is the generation the console's M.2 slot actually uses — so nothing here is oversold by a generation it cannot run at.
Two things in the same listing do not settle so neatly. One of the reviews we hold reads 'Good Cost effective 1TB storage replacement' on a page for a 4 TB drive. And the rating breakdown we hold adds up to 100 reviews — 81 five-star, 8 four-star, 3 three-star, 1 two-star and 7 one-star — while the listing itself shows 899 ratings. Everything on this page is taken from the Amazon listing as it stands, not from a drive we have benchmarked ourselves.
How those 899 ratings break down
An average hides its own shape. This is the spread behind the 4.5 stars.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“Good Cost effective 1TB storage replacementMy Windowsn11 PC baked alive and trashed the SSD, not bad for 4 years hard labour.Cost per GB made this a great selection for an Ubuntu 26.04LTS conversion.”
Verified purchase“Very please with this drive. My first experience with an NVMe drive and I am very impressed with how noticeably faster it is starting up Windows that my SATA ssd. Wasn't expecting such a difference but it feels not dissimilar to my first experience when moving from HDD to SSD.Also looks very striking with its colourful heatsink and comes with a handy little multi-tool screwdriver and spare standoff screws.”
