About IBM Deskstar 180 GXP
Deskstar 180GXP is the world’s fastest (IDE interface) desktop hard disk drive with IBM-exclusive technology called “tag ‘n seek” for its simplicity. Known technically as tagged command queuing, “tag ‘n seek” technology enables the drives to perform nearly 25 percent faster than its predecessor and widen the Deskstar performance gap over competitors by up to 20 percent. Formally announced in September 2002, Deskstar 180GXP is a 7200RPM drive with maximum cache size of 8 MB and highest capacity offering at 180GB.
