The WD Se is an enterprise class drive designed for use in a NAS or data warehouse. Unlike the Enterprise Xe, which focuses on maximum data throughput, the focus of the Se is on balanced performance, power consumption and reliability. We only have one sample for this drive at present so for now we can't draw any robust conclusions. Based on the data we do have, in terms of value for money the WD Se lands in the middle of the (scarce) 4TB pack, besting the (2012) 4TB black by just 3.4%. From a performance perspective, with both peak and average read/writes coming in at 137/136 MB/s it's hard to tell at this point because we don't know whether to take those figures as peak or average. As averages they are very strong and as peak figures they are relatively weak. We will update this summary when we have more data. In the mean time the Seagate Desktop HDD1.5 remains our 4TB pick. [Jan '14 HDrivePro]


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]
