Pros & Cons

Pros

✓ Up to 7450MB/s sequential reads and 6500MB/s writes over PCIe 4.0 x4
✓ Up to 1000K random read/write IOPS for fast game loads and app launches
✓ 3D TLC NAND across the full 4TB capacity
✓ Pre-fitted 0.5mm graphene aluminium heat sink helps sustain top speeds
✓ Free Biwin Intelligence app for data migration, speed tests and firmware updates

Cons

✗ Relies on Host Memory Buffer (HMB), which borrows a slice of system RAM
✗ No TBW endurance rating or warranty terms given in the product details
✗ Drops to Gen3 speeds in a PCIe 3.0 M.2 slot
✗ Pre-fitted heat sink may clash with a motherboard's own M.2 shield

Manufacturer description

The BIWIN Black Opal NV7400 4TB SSD is a PCIe 4.0 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. Random performance reaches up to 1000K IOPS, so large game installs, 4K video projects and big photo libraries load quickly. BIWIN uses 3D TLC NAND across the full 4TB capacity, which is enough for a large game library or a full project archive on one drive. A power management IC (PMIC) spreads power more efficiently to cut energy use and help the drive last longer. A pre-fitted 0.5mm graphene…

SpecPicks Verdict

SpecPicks scored BIWIN Black Opal NV7400 4TB SSD Gen4x4 using a rating × review-volume × price-fit model applied to published specs and reviews across the ssds & storage category. BIWIN's ssds & storage lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for ssds & storage of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.

Frequently Asked Questions

Does the BIWIN NV7400 4TB work in a PS5?

Yes. BIWIN lists the PS5 as a supported system. The drive is PCIe 4.0 x4 NVMe in the M.2 2280 size, which is what the PS5 expansion slot uses, and it comes with a pre-fitted 0.5mm heat sink. Check that it clears the slot cover in your console before you close it up.

How fast is the NV7400 compared to a Gen3 SSD?

It is rated for up to 7450MB/s sequential reads, 6500MB/s sequential writes and up to 1000K random IOPS. That is roughly double the ceiling of a PCIe 3.0 x4 slot. In a Gen3 slot the drive still works, but only at Gen3 speeds.

Does it have a DRAM cache?

BIWIN lists Host Memory Buffer (HMB) technology and Smart Cache. HMB uses a small portion of your system RAM as the drive's mapping cache instead of a dedicated onboard DRAM chip. For firmware-level details, check the product listing or contact BIWIN.

Will it fit in my laptop?

It uses the standard M.2 2280 size (22mm wide, 80mm long) and needs an M.2 slot that supports NVMe PCIe. The 0.5mm heat sink adds a little thickness, so check your laptop's clearance for the M.2 bay before you buy.

How do I move my old drive's data to the NV7400?

Use the free Biwin Intelligence software. It includes data migration, performance tests and firmware updates for BIWIN consumer drives. The listing does not state the warranty and endurance terms, so check the manufacturer's current policy.
