A leaked datasheet reveals Western Digital is working on a new line of VelociRaptor hard drives for enterprises. These 2.5" disks offer up to 200GB per platter and will be available in capacities of 150GB, 300GB, 450GB or 600GB. The VelociRaptors can be shipped in an optional 3.5" enclosure, but because these 10,000RPM disks have a bigger height than regular 2.5" HDDs you can't use them in laptops.
The new VelociRaptor VR200M promises sustained read speeds of 145MB/s, average read seek times of 3.6ms and average write seek time of 4.2ms. Power consumption ranges from 0.7W in sleep/standby to 4.3W in idle and up to 6.8W during sequential read/write operations.
Performance seems to be about 15 percent higher over previous generation VelociRaptor drives.
