The focus of this PCSTATS review is Seagate's 2TB Backup Plus Slim external USB 3.0 hard drive. The Backup Plus Slim is a self-contained 2.5" SATA-600 interface hard drive in a black aluminum and plastic enclosure which connects via USB 3.0 cable to any PC or Mac computer. The whole package weighs 150 grams and is just over 12mm thick - about the size of a smart phone. Power for the drive is supplied via the USB 2.0 or USB 3.0 port. The Backup Plus Slim looks every bit like the Monolith from Kubrick's 2001:A Space Odyssey, but inside is a not particularly remarkable 5400RPM, 3-platter hard disk with 32MB of cache.
