In the Solid State Drives portfolio
The Gold P31 built its reputation on efficiency: full Gen3 saturation at 3,500 MB/s read while drawing markedly less power than competing drives, a result of SK hynix's 128-layer NAND and in-house controller. Independent testing repeatedly placed it top of its class in performance per watt.
That profile keeps the P31 relevant for notebook upgrades, fanless mini-PCs, and battery-critical field systems on Gen3 platforms. Capacities run 500 GB to 2 TB with a five-year warranty.
