Product overview Released on 2020-08-18, the SK hynix Gold P31 1TB is a PCIe 3.0 x4 NVMe M.2 2280 SSD in the Gold P31 family, built around SK hynix’s in‑house controller and 128‑layer TLC NAND. It remains available on the manufacturer’s site.
By our storage scale it’s a budget-tier NVMe option: a top‑of‑Gen3 drive that exists for users who want cool, very power‑efficient storage without paying for Gen4 bandwidth. With a DRAM cache and rated up to 3,500/3,200 MB/s, its single‑sided 1TB design is well‑suited as a boot drive and game library in desktops and laptops. Endurance for the 1TB model is rated at 750 TBW, sufficient for everyday workloads and light editing scratch. Notably, the Gold P31 was the first consumer SSD to ship with 128‑layer NAND.
