Western Digital has announced an expansion to their SATA drive lineup today, in particular their Enterprise-class drives. The new drive will be a member of the “RE” family, and will boast all the suite of features that WD sells their RE drives on. They claim the new disk is a significant step up in terms of performance, with features such as dual HDD controller processors to handle large amounts of data, shock sensors, vibration detection and a lot more.
It also supports an interesting feature that allows the drive to adjust a head's height, in order to improve reliability. If a HDD head comes into contact with the platters, you shortly thereafter have a damaged disk. The technology to adjust the head height is not new, but is supposedly improved in this model. The units are available in sizes up to 500GB, with a price tag of $119 for that particular model. That's a bit more expensive than their standard SATA disk line, which is expected as they certify these drives as being more reliable for use in “endurance” environments such as datacenters.
