This is the latest version of Western Digital's mid-range Blue drive. At only one year of age this drive is relatively new and the performance figures reflect this. With maximum sequential speeds of 180 MB/s (both read and write) the Blue is amongst the faster drives currently available and in terms of real world performance it beats its predecessor the 2010 Blue (WD10EALS) by around 18%. The 2012 Blue has a single 1TB platter which combined with its 7200 rotation speed allow for above average performance across the board. In terms of value for money a larger capacity drive will nearly always be a better choice but within the 1TB category as a system drive, the 2012 Blue is a very reasonable, if not the best, option. [Jan '14 HDrivePro]


This version (WD10EALS) of Western Digital's mid-range blue series drive is nearly four years old and as such not a good choice as a new purchase. This drive operates at 7200 RPM and has two 500GB platters which allow it to sustain reasonable sequential transfer rates of up to 180 MB/s read and 140 MB/s write. Average transfer rates are below this by nearly 50% and this version of the blue exhibits particularly weak throughputs of just 50 MB/s when faced with mixed IO (simultaneous reading and writing). Overall as a new purchase the newer single platter 1TB Blue 2012 Blue (WD10EZEX) is a far better choice and offers nearly 20% better average performance. [Dec '13 HDrivePro]
