Product fully in line with my expectations. Given its capacity to 2 TB, size and weight of this record make it a valuable asset for mobility. Perfect for backups, but also for storing videos, photos, music ... Hard self-powered by USB, once connected with the cord, the Western Digital My Passport is immediately recognized under Windows 7 X64. I loaded the disc half, that is to say a little less than 1000 GO continuously with a rate cut 3 USB breath! the announced figures of 122 MB / second read and 110 mb / s write are not usurped. And surprisingly this record virtually no heat. Design side no complaints - slightly stockier than his counterpart from 1 TO - Quiet - just missing a small protective cover for transport. One drawback, its tariff: Purchased 156 on Amazon - including postage and it is the best price found on the Net to that capability! Fingers crossed for reliability ... only time will make the difference.
