WD My Passport Ultra Metal Edition External Hard Drive 2TB (6.3 cm (2.5 inches), 5400rpm, 8MB cache, SATA, USB 3.0) Silver (accessory)
Positives: The WD My Passport Ultra achieves an average transfer rate of 113 MB / s, faster than all my 5 pcs. external hard drives. Very quiet, inaudible to me, since my NB makes fan noise. The aluminum housing looks dibasic. What I do not like: 1.
