1TB SATA SSD for consumer upgrades

This 2.5 inch SanDisk drive uses 3D NAND TLC and a SATA III interface to deliver sequential reads up to 560 MBps and writes up to 520 MBps. It is built for everyday workloads on laptops and desktops.

Suits SATA 2.5 inch bays; not for M.2 only slots

The 7mm height fits most standard drive bays and caddies. Systems limited to M.2 connectors cannot accept this form factor. Random performance reaches 90,000 read IOPS and 82,000 write IOPS for responsive multitasking.

Verify SATA power, data cable and 7mm clearance

Confirm your motherboard or laptop has a free SATA III port and a 2.5 inch bay with 7mm height allowance. The drive draws 60 mW average active power and operates from 0°C to 70°C. Acronis True Image for Western Digital is included for cloning.

Questions about this item

Does my laptop need a free 2.5-inch drive bay and a SATA data cable to install the WD Blue SA510?

Yes, the drive fits a standard 2.5"/7 mm bay and connects through a SATA III port; you will need both a spare bay and a SATA data cable.

Will the WD Blue SA510 work in an older PC that only supports SATA II 3 Gb/s?

The SSD is backward compatible with SATA II, so it will function in older systems, but sequential speeds will be limited to the 3 Gb/s link.

How can I verify the WD Blue SA510 is healthy and performing at up to 560 MB/s read after installation?

Use the downloadable Western Digital SSD Dashboard to check drive health, temperature and available space, and run a benchmark to confirm read speeds near 560 MB/s.
