6.2/10verdict: wait for deal

The Black Opal NV7400 is a PCIe 4.0 M.2 2280 drive for builders who want fast sequential speeds and a 5-year warranty. It suits gaming PCs, workstations and laptops where a single-sided drive with a bundled thermal pad is useful. It is less suited to anyone who needs steady writes under heavy sustained load or strong small random I/O.

6.9/10verdict: buy

The Crucial P510 1TB suits buyers who want a PCIe 5.0 x4 M.2 drive with high rated sequential speeds and low reported heat. It fits workstations and homelab hosts that mostly do bursty reads and moderate writes. Buyers who write large volumes continuously, or who want a bargain price, should check the cache and value notes first.
