Hitachi Intros Deskstar 7K and 5K Hard Drives with 3 TB Capacities

btarunr · Nov 15, 2010, 12:56 PM

Hitachi listed two of its new mammoth-capacity hard drives on its website, the Deskstar 7K3000 and Deskstar 5K3000. These drives are available in capacities of up to 3 TB; 2 TB and 1 TB variants are also available. The drives have spindle speeds of 7200 rpm (for the 7K3000) and 5400 rpm (for the 5K3000). Available in the 3.5-inch form factor, these drives use the SATA 6 Gb/s interface, but are backwards compatible with SATA 3 Gb/s and 1.5 Gb/s. The 7K3000 uses a 64 MB cache, while the 5K3000 makes do with 32 MB. Both drives have default sector sizes of 512 bytes. The company is yet to reveal pricing.

I've always been sketchy about large storage devices. Do we know how many platters are in the 3tb HDDs?

For the WD Caviar Green 3TBs, it's 4-platters.

Since the older 72K2000s (2TB) have 5 platters I'm guessing these do too. I doubt it would be more space with less platters.

I have 2 of the 72K2000s and they have been damn good drives in the year I've had them. They seem to be really popular as well.

5 platters (600 GB) compared to WDs 4 platters (750 GB).

These might cost less, though.
