Not so long ago Seagate released the Cheetah X15 , and they have another surprise for us. The ST1181677LWV is by far the largest hard drive that the world has ever seen. With a capacity of 180 GB, it is more than twice as large as the previous record-holders, Maxtor's DiamondMax 80 and Western Digital's WD800BB drive. In terms of capacity, both of these IDE drives lose the crown to Seagate's new SCSI drive.
The amount of platters had to be increased considerably in order to reach this formidable capacity. As a result, the Barracuda 180 makes use of 12 discs, which, because of the sheer amount, can no longer be placed in a standard 1" high case. To install this drive, you will therefore require two free 3.5" drive bays.
