WD really a good product in which one can trust to keep your data safe! I always used WD and I am very happy with their qualities. Besides with USB 3.0 it goes very fast, for my part with Asus ROG G75VW-T1432H - SSD Edition and other WD DD speed up to 130 MB / s and I copied over 200 GB in 30 minutes ! Finally, it is mainly to say that WD does not heat malgrès high-speed transfers and large capacities. Go there trust me go for it! For backups of photos, videos and other large files is really ideal, bravo Western Digital!
