250GB SATA III SSD for consumer upgrades

The SanDisk WDS250G3B0A-00AXR0 is a 250GB internal solid-state drive built on 3D NAND TLC memory. It uses the SATA III 6 Gb/s interface in a 2.5-inch form factor and is rated for consumer workloads. Sequential speeds reach up to 555 MB/s read and 440 MB/s write, with 4KB random performance of 80,000 IOPS read and 78,000 IOPS write. Endurance is rated at 100TB written and MTTF up to 1.75M hours.

Straightforward 2.5-inch SATA installation

The drive fits standard 2.5-inch drive bays and connects through a regular SATA data and power cable. No additional drivers are required for modern operating systems. The main issue is forgetting to initialise the new volume in disk management, which leaves the drive invisible in the file explorer. Cloning software is available as a download, but the process can stall if the source disk has bad sectors or if the target drive is not set as the first boot device after migration.

Verify SATA port and bay clearance before ordering

Confirm the motherboard or laptop has a free SATA III port and that the 2.5-inch bay accepts a 7mm drive height. Check that the system BIOS recognises SATA AHCI mode for best performance. Ensure the power supply provides a spare SATA power connector. The drive operates between 0°C and 70°C, so verify case airflow meets this range. Active power draw peaks at 2,000 mW during writes, while idle slumber is 36 mW and DEVSLP is 12 mW.

Questions about this item

How can I verify the 250GB WD Blue SA510 is performing correctly after installation?

Use the Western Digital SSD Dashboard to check that the drive reports 250GB capacity, 3D NAND TLC memory, SATA III link speed, and SMART health status showing 100% life remaining.

What is included with the WDS250G3B0A and what must be purchased separately?

The box contains the 2.5-inch 250GB SSD and a download licence for Acronis True Image for Western Digital cloning software; a SATA data cable, power cable, and 2.5-to-3.5-inch bracket are not included.

Which WD Blue SA510 capacity should I choose for my workload?

The 250GB model delivers up to 555 MB/s read and 440 MB/s write with 100 TBW endurance; larger 500GB and 1TB versions reach 560 MB/s read if you need more space and higher write endurance.
