WD Blue 2TB SATA SSD for consumers

The Western Digital WDS200T2B0A is a 2TB internal solid-state drive built with 3D NAND technology for consumer workloads. It connects through a SATA III interface and fits the standard 2.5-inch form factor. Sequential read reaches 560 MBps and sequential write reaches 530 MBps, while random performance delivers 95,000 IOPS read and 84,000 IOPS write. The drive is rated for 500 TBW and an MTTF of 1.75M hours.

Thermals noise and power in daily use

Operating temperature spans 0°C to 70°C, with storage tolerance from -55°C to 85°C. Average active power draw is 60mW, peaking at 3,000mW during max read and 3,800mW during max write. Idle consumption drops to 56mW in slumber and as low as 12mW in DEVSLP. With no moving parts the drive produces no audible noise during operation.

Build fit SATA power and 7mm bay

The 2.5-inch 7mm profile slides into any standard drive bay or caddy that accepts a SATA data and power connection. Low active power helps extend battery life in laptops, while the 500 TBW endurance supports heavy write workloads. WD F.I.T. Lab certification confirms broad system compatibility. Free downloadable software provides drive monitoring, cloning and backup functions.

Questions about this item

How do I install the 2.5" SATA drive and what step is often missed?

Mount the 2.5" drive in a 2.5" bay or use a 2.5-to-3.5 adapter, connect the SATA data and power cables, then enable AHCI mode in BIOS so the SATA III interface runs at full speed — skipping AHCI is the common oversight.

What maintenance or replacement will the 3D NAND SSD need later?

The 3D NAND SSD has no moving parts to service; monitor health with the free downloadable software and plan replacement once the 500 TBW endurance rating or the 1.75M-hour MTTF threshold is approached.

What limit appears first during sustained writes on this SATA III drive?

The SATA III 6 Gb/s interface caps sequential write throughput at 530 MB/s, so the interface bottleneck arrives before the 3D NAND or controller reaches its own thermal or current limits.
