Western Digital is the king of the hard drive market but up to now has been a non-factor in SSDs. However, with its purchase of solid state storage giant, SanDisk, the company immediately leaped to the forefront of the market in one fell swoop.

Now the company is entering the consumer/commercial SSD market with WD Green and WD Blue SSDs, using a naming scheme borrowed from its hard drive line and technology acquired from SanDisk. WD's Green lineup is for entry level PCs meant to have a low power draw, while the Blue SSD series is aimed at mainstream consumers. Both series are available in both 2.5? SATA III and M.2 SATA III form factors.
