Manufacturer description

Upgrade an aging laptop or desktop and the WD Green 1TB SSD (WDS100T2G0A) is the low-friction path: a standard 2.5-inch, 7mm SATA III 6 Gb/s drive that drops into any bay a spinning hard disk used to occupy. Western Digital rates it at up to 550 MB/s sequential reads, with SLC caching stepping in to speed up the write bursts that dominate everyday work — booting, installing updates, opening project files. The drive is shock-resistant and carries WD F.I.T. Lab certification, meaning Western Digital has validated it against a broad range of PC configurations before it ships. Ultra low power…

Frequently Asked Questions

How fast is the WD Green 1TB SSD?

Western Digital rates it at up to 550 MB/s sequential read over the SATA III 6 Gb/s interface, which is close to the practical ceiling for any SATA SSD. SLC caching boosts write performance during everyday tasks. WD does not publish a sequential write figure for this model.

Will this SSD fit my laptop?

It uses the standard 2.5-inch, 7mm form factor, so it fits any laptop or desktop bay built for a 7mm 2.5-inch drive. WD F.I.T. Lab certification means it has been tested for compatibility across a wide range of PCs. Machines that only accept M.2 drives are not compatible.

What warranty comes with the WD Green SSD?

Western Digital includes a 3-year limited warranty. Check the product listing for current terms and regional coverage before you buy.

Does it come with cloning or monitoring software?

Western Digital offers the free WD SSD Dashboard as a download, which lets you monitor drive status, health, and firmware. It is not bundled in the box; you download it from WD after installing the drive.

Is the WD Green a good pick over a mechanical hard drive?

For a laptop, yes on two counts: the drive is shock-resistant with no moving parts, and its ultra low power draw extends battery runtime versus a spinning disk. This upgrade has become routine.
