The last Hitachi hard drive we reviewed, the Deskstar 5K3000, was surprisingly fast, competing directly with 7200 RPM drives despite being positioned as an eco-friendly model with a 5940 RPM motor. It also impressed in other areas, being fairly energy efficient, lacking in vibration and generating very little in the way of airborne noise. We hope to see more of the same from a member of their mainstream Deskstar 7K3000; hopefully the presence of a "proper" 7200 RPM motor boasts performance without making too many sacrifices.


The Hitachi Deskstar 7K3000 2TB.

The Deskstar 7K3000 offers all the usual modern amenities like a 6 Gb/s SATA interface, 64MB of cache, and the usual promises of high performance and improved energy efficiency over previous models. The one feature you won't find on 7K3000 (or 5K3000) is 4 kilobyte advanced sectors. Hitachi appears to be the lone holdout amongst hard drive manufacturers, still relying on the old system of 512 byte sectors. Our sample is a 2TB version with three platters just like the 5K3000 we reviewed a few months ago. It's also available in 1.5TB and 3TB models.


The underside.

Like previous Hitachi offerings, the drive is noticeably nondescript with a plain-Jane metal exterior and lacking the support ribs found on the WD Caviar Green and Samsung EcoGreen series. Thankfully the hard drive is one of the few PC components have yet to be exploited by manufacturers as a vehicle for bright LEDs.
