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.
