2TB SATA SSD for everyday computing

The WD Blue WDS200T2B0B is a 2TB internal solid-state drive built for consumer workloads. It uses 3D NAND flash and a SATA III interface in the M.2 2280 form factor. Sequential read reaches 560 MB/s and write reaches 530 MB/s. Random performance hits 95,000 IOPS read and 84,000 IOPS write.

Fits M.2 slots with SATA wiring

This drive slides into any M.2 2280 slot that routes SATA signals, not PCIe. It needs no extra power cable and draws 60 mW average active power, peaking at 3,000 mW reading and 3,800 mW writing. Idle consumption drops to 56 mW in slumber or 5 to 12 mW in DEVSLP. Free WD SSD Dashboard software lets you monitor health and clone drives.

Steady output within 0 to 70 °C

The drive is rated for 500 TB written and 1.75 million hours MTTF. Operating temperature spans 0 °C to 70 °C, while storage tolerates -55 °C to 85 °C. WD F.I.T. Lab certification confirms compatibility across a wide range of laptops and desktops. These figures reflect sustained operation rather than short bursts.
