The WD Green 120GB is Western Digital's entry-level SATA SSD, built for the simplest and most common upgrade there is: replacing a slow mechanical hard drive in an older laptop or budget desktop. It uses a standard 2.5-inch, 7mm form factor over SATA III 6 Gb/s, so it drops into virtually any bay or caddy without adapters, and reads run up to 550 MB/s. SLC caching absorbs short bursts of write activity, which is what you actually feel when booting Windows, opening a browser, or launching an application. Western Digital rates the drive as shock-resistant and puts it through WD F.I.T. Lab…
