Seagate released the first of a 1.5TB hard drive for desktop computers. The jump from 1TB to 1.5TB is the “largest capacity hard drive jump in the more than half-century history of hard drives”, according to Seagate. The revolution was possible thanks to the perpendicular data recording technology (PMR). The hard drive Barracuda 7200.11 works with desktops, workstations, RAID-massives, game/hi-end computers and external memory devices that support USB/FireWire/eSATA interfaces. The Serial ATA interface (3GB/sec) provides high speed of data transferring (up to 120 MB/sec for fast downloads, launching of applications and access to information. The hard disk’s capacity varies from 1.5TB to 160 GB with cash memory capacity 32Mb and 16Mb. The 1.5Tb disks Momentus 5400.6 and Momentus 7200.4 with spindle speed 5400 RPM and 7200 RPM are designed for notebooks, external harddrives and other solutions that require physically small disks.
