SATA III M.2 2280 500GB SSD

The Western Digital WD Blue WDS500G2B0B is a 500GB internal solid-state drive built with 3D NAND technology. It connects through a SATA III 6Gb/s interface in the M.2 2280 form factor. Sequential reads reach up to 560 MB/s and writes up to 530 MB/s, while random 4KB performance hits 95,000 read IOPS and 84,000 write IOPS.

Suits SATA M.2 slots and modest capacity needs

This drive fits laptops and desktops that provide a SATA-based M.2 socket and want a 500GB capacity boost. It is rated for 1.75M hours MTTF and 200 TBW, with active power averaging 52mW and idle as low as 5-7mW in DEVSLP. Systems limited to PCIe-only M.2 slots or those requiring higher throughput should consider a different interface.

Fits a SATA M.2 socket and frees a 2.5 bay

Installation requires a motherboard or laptop with an M.2 2280 slot wired for SATA signalling. The stick layout leaves the traditional 2.5-inch bay empty for additional storage. Free downloadable software supports drive monitoring, cloning and backup. Operating temperature spans 0°C to 70°C, and shock resistance is rated at 1500G.
