The questions that come up before an order
Who makes it?
The fifth bullet names Biwin Intelligence as the management software for Predator-branded storage, the same software the BIWIN NV7400 on this shelf names.
What does thermal throttling mean here?
The drive slows itself down when it gets too hot. The fourth bullet presents it as temperature control; without a heat sink, sustained writes in a warm laptop are where it shows.
Our score
7.6/ 10
Gen 4 ×4 speeds with the cache arrangement named and cloning software included, on a page without endurance or warranty figures.

1 TB · M.2 2280 · PCIe Gen 4 ×4 · 7,450 MB/s read · 6,500 MB/s write · 1,000K IOPS · HMB · 0.5 mm heat sink · no TBW or warranty
A Gen 4 drive with the highest read figure on this shelf, 7,450 MB/s, a random figure of up to 1,000K IOPS and a thin heat sink — and no endurance rating or warranty term on its Amazon.com page.
Best for: A desktop or laptop Gen 4 slot where the highest read figure on this shelf is wanted and a written warranty is not essential.
1 TB · M.2 2280 · PCIe Gen 3 ×4, NVMe 1.3 · 2,100 MB/s read · 1,700 MB/s write · no endurance, warranty or cache figure
The only Gen 3 drive on this shelf and the cheapest at $151.41 on Amazon.com on October 26, 2026: 1 TB in M.2 2280, 2,100 MB/s read and 1,700 MB/s write, and no endurance, warranty or cache figure.
Best for: A machine with a Gen 3 M.2 slot, where a Gen 4 drive would run at Gen 3 speed anyway.
The cheapest Gen 4 drive on this shelf at $168.99 on Amazon.com on October 26, 2026, and the only one whose listing states an endurance rating — 600 TBW — beside a three-year warranty.
Best for: A desktop, laptop or PS5 slot where the lowest Gen 4 price and a written endurance figure both matter.
