HotHardware.com posted a review on Seagate's Barracuda ES.2 1TB SAS Hard Drive

Today, we'll be showcasing one of the most significant developments to date, toward getting SAS (Serial-Attached SCSI) more frequently into the vernaculars of workstation/server buyers and maybe even a few enthusiasts - relatively cheap, high-capacity SAS storage thanks to Seagate. Seagate currently offers 10,000 and 15,000 RPM disks with SAS interfaces at a fraction of the capacity versus SATA offerings and as such, much higher prices.

However, Seagate just launched their Barracuda ES.2 platform with a SAS interface that offers capacities up to 1 Terabyte (1 TB). Not only is the Barracuda ES.2 the highest capacity SAS disk to date, it's also the first SAS disk we've seen on the market with a 7,200 RPM spindle speed and SATA-like pricing.
