BIWIN Black Opal NV7400 Gen4x4 NVMe M.2 Internal SSD

The BIWIN Black Opal NV7400 is a Gen4x4 NVMe SSD that leads with speed. In its 512GB configuration, it uses the widely supported M.2 2280 form factor and the PCIe 4.0 interface, a combination aimed squarely at power users who want current-generation throughput without moving up to the largest, priciest capacities. BIWIN positions it for laptops, desktops, and the PlayStation 5, three platforms that all accept the standard 2280 length. The headline numbers are ambitious: sequential reads up to 7450MB/s, sequential writes up to 6500MB/s, and random read and write performance rated at up to 1000K IOPS.

Those specifications sit near the top of what Gen4x4 can deliver, which is the drive's central selling point. Fast sequential reads help with loading large files and games, while high random IOPS speaks to the many small operations that shape how quick a system feels day to day. On construction and ownership, the source material is lean: it confirms the 2280 form factor, the PCIe 4.0 Gen4x4 interface, and the 512GB capacity, but does not detail controller, NAND type, endurance, or thermal hardware. Buyers who plan to install it in a PS5 or a compact laptop should confirm cooling and clearance for themselves, since the listing centers on performance rather than physical extras.
