AnandTech has pitted two 320 GB HDDs in a battle royal, one from Western Digital and one from Seagate.  Both are fast drives for their size, and even better they are quiet and relatively cool.
“We are looking at Western Digital’s WD3200KS product today that features a 16MB drive buffer, native 3Gb/s SATA support, 320GB capacity, and 7200 RPM spindle speeds. The SE16 series is available in 250GB, 320GB, 400GB, and 500GB capacities and is considered to be Western Digital’s High Performance desktop series. This series also features WD’s advanced acoustic technologies, Whisperdrive and Softseek. The 400GB drive offers 1.5Gb/s SATA support while the other drives offer 3Gb/s SATA support but lack Native Command Queuing as Western Digital believes this technology does not benefit the typical desktop user.

Seagate recently announced the Barracuda 7200.10 as the successor to their Barracuda 7200.9 series. The Barracuda 7200.10 series consists of drives ranging in capacity from 200GB to 750GB along with UltraATA/100, SATA 1.5Gb/s, or SATA 3Gb/s interfaces and 8MB or 16MB of cache depending upon the drive model. As with previous Barracuda product group updates the naming succession follows the standard point upgrade path but this change is anything but a simple number revision. The new Barracuda 7200.10 product is the first desktop centric hard drive to feature perpendicular recording.”
