If you use several different capacity storage drives Toshiba has unveiled a new line of STOR.E ART external hard drives that are color coded depending on their storage capacities. The 2.5″ drives will come in 500GB (red), 640GB (green), 750GB (blue), 1TB (white) and 1.5TB (silver).
That should help you keep track of things. Each STOR.E ART drive has a USB 3.0 interface, 256-bit encryption, and comes preloaded with BackupNow EZ software for easy backups. These new drives should arrive in the first quarter of 2011, but we have no info on pricing yet from Toshiba.
