600GB per platter, anyone? Hitachi’s new Deskstar 7K3000 and 5K3000 3TB desktop hard drives have quietly shown up on its website. The 7K3000 has a 7200rpm rotational speed and 64MB of cache, while the 5K3000 has CoolSpin technology and 32MB of cache. Both drives have a SATA 6Gb/s interface and are also available in 2TB and 1.5TB.
Hitachi’s new Deskstar 7K3000 and 5K3000 3TB desktop hard drives have quietly shown up on its website. Interestingly, there is no press release is available for both products yet.
The new Hitachi desktop flagship, Deskstar 7K3000, has a 7200rpm rotational speed, 64MB of cache and a SATA 6Gb/s interface. Hitachi claims the new drive is up to 27% faster than the previous generation, and that would be the 7K2000. There are three models available in the 7K3000 family: 3TB (HDS723030ALA640), 2TB (HDS723020BLA642) and 1.5TB (HDS723015BLA642).
On the other hand, Hitachi has also released the Deskstar 5K3000, with has CoolSpin technology and 32MB of cache, for those who are looking at saving power, cool running drives and quiet computing. CoolSpin is Hitachi-speak, similar to Western Digital’s Caviar Green IntelliPower – both companies do not reveal the actual rotational speed of their low-powered drives. Also, the 5K3000 has a SATA 6Gb/s interface, and is available in the same capacity points: 3TB (HDS5C3030ALA630), 2TB (HDS5C3020ALA632) and 1.5TB (HDS5C3015ALA632).
The 3TB models are both five-platter drives (like all previous highest capacity Hitachi models) – each platter has a density of 600GB. That means the 2TB uses four platters, and the 1.5TB uses three.
We will update again when the official press release goes around.
