WD achieves 4.6GB per platter

Western Digital is shipping evaluation units of 3.5-inch disk drives that pack 9.1GB and 18.3GB at 4.6GB per platter. The 10,000rpm devices use the Ultra2 SCSI LVD interface. Production shipments are expected this summer. Later in the year, Western Digital plans to ship Fibre Channel Arbitrated Loop (FC-AL) and Ultra 160/m SCSI versions of the drives.

The drives use 95mm media and giant magneto-resistive (GMR) heads, and have a power consumption of 10W, 360MBps data rate, and 5.2msec seek time. A 2MB cache is standard; 8MB cache optional.
