BIWIN Black Opal NV7400 Gen4 SSD 1TB

6.2/10verdict: good, not the best

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.

Kingston NV3 PCIe 4.0 NVMe SSD

5.9/10verdict: good, not the best

The Kingston NV3 suits buyers who want a cool, low-power PCIe 4.0 M.2 drive for everyday use and light server or homelab duty. It is a budget-minded option with a five-year warranty and Kingston's SSD Manager tool. It is a weaker fit for anyone who writes large amounts of data or needs confirmed hardware details.
