Capacity and audience

This 2TB 2.5" SATA III internal SSD uses 3D NAND TLC memory and targets consumer laptops and desktops that need a straightforward storage upgrade. It delivers sequential reads up to 560 MBps and writes up to 520 MBps with random performance of 90,000 read IOPS and 82,000 write IOPS.

Thermals noise and power

The drive operates between 0°C and 70°C and draws 60 mW average active power, peaking at 1,800 mW during reads and 2,000 mW during writes. Idle slumber power is 36 mW and DEVSLP drops to 12 mW, helping extend battery life in portable systems.

Software and accessories

Acronis True Image for Western Digital is included for full-drive cloning and backup with cyber protection features. The downloadable Western Digital SSD Dashboard adds health, temperature, and capacity monitoring to simplify ongoing maintenance.

Questions about this item

How do I install the 2.5" 7mm drive in a laptop bay, and what step is often missed?

Mount the drive using the four screw holes on the 69.85mm x 100.20mm frame, connect the SATA data and power cables, then enable AHCI mode in BIOS so the SATA III 6 Gb/s link negotiates at full speed.

What maintenance will the 3D NAND TLC drive need and when should I plan a replacement?

No mechanical service is required; monitor health with the downloadable Western Digital SSD Dashboard and replace the drive once the 200TB TBW rating or the 1.75M hour MTTF threshold is approached.

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

The sequential write ceiling of 520 MBps and the 82,000 IOPS random write limit are reached before thermal throttling, since the drive operates within 0°C to 70°C and draws a maximum of 2,000 mW during write bursts.
