Like its predecessor -- the 3.5-inch A7K2000 -- the new drive has five platters, but it increases the areal density on those disks by 50% from 400GB per platter to 600GB. This means that datacenters could save energy by delivering the same level of storage using fewer drives. Hitachi also claims to have increased the mean time before failure rating of the drive to two million hours, resulting in a failure rate around 40% lower than the industry average (1.2 million hours MTBF).
Both Ultrastar 7K3000 models are available with regular and bulk data encryption (BDE) options. Although Hitachi made no mention of pricing, the SATA versions are already shipping, while the SAS models are expected around mid-year.
