Pros & Cons

Pros

  • ✓ Up to 7450MB/s sequential reads and 6500MB/s writes on PCIe Gen4 x4
  • ✓ Random read/write rated up to 1000K IOPS for snappy app and game loads
  • ✓ 3D TLC NAND rather than QLC for steadier sustained writes
  • ✓ 0.5mm graphene aluminium heat sink stays slim enough for laptops
  • ✓ Free BIWIN Intelligence app handles data migration and firmware updates

Cons

  • ✗ Warranty length and TBW endurance rating not stated in the listing
  • ✗ Relies on Host Memory Buffer; onboard DRAM cache is not listed
  • ✗ Quoted speeds are series maximums; 1TB write figures may be lower
  • ✗ PCIe 3.0 slots cap throughput well below the rated 7450MB/s

Manufacturer description

The BIWIN Black Opal NV7400 1TB SSD is a PCIe Gen4 x4 NVMe drive in the standard M.2 2280 size. It fits desktops, laptops and the PS5. Sequential reads reach up to 7450MB/s and writes up to 6500MB/s, with random reads and writes rated at up to 1000K IOPS. That is enough headroom for faster game loads, large project files and quick boot times on a Gen4-capable system. The drive uses 3D TLC NAND. A composite power management IC (PMIC) distributes power more efficiently, which BIWIN says saves energy and extends the SSD's durability. A 0.5mm graphene aluminium heat sink spreads heat so the…

Frequently Asked Questions

Will the BIWIN NV7400 1TB work in a PS5?

Yes. It is listed as compatible with the PS5 and uses the M.2 2280 form factor with a PCIe Gen4 x4 interface, which matches the console's expansion slot.

How fast is the BIWIN NV7400 SSD?

BIWIN rates it at up to 7450MB/s sequential read and 6500MB/s sequential write, with random read/write performance of up to 1000K IOPS.

Does the NV7400 come with a heatsink?

It has a 0.5mm graphene aluminium heat sink that spreads heat and helps hold top speeds under sustained load. Its thin profile helps it fit laptops.

Can I use the NV7400 in a PCIe 3.0 motherboard or laptop?

PCIe 4.0 NVMe drives generally work in PCIe 3.0 M.2 slots, but speeds are limited by the older interface. To be sure, check your system's M.2 slot support and the product listing.

How do I move my existing system to the NV7400?

Use BIWIN Intelligence, BIWIN's free management software. It includes data migration, performance testing and firmware updates for BIWIN consumer storage drives.
