Seagate's Barracuda ES.2 hard drive

Seagate first dipped its toe into the enterprise SATA market with the Barracuda ES, which was based on the company's then-current 7200.10 drive technology. Since then, Seagate has rolled out a 7200.11 drive platform, and with it, a new Barracuda ES.2. With a terabyte of total capacity spread over four 250GB platters and 32MB of cache, the ES.2 looks great on paper. But how does the drive's performance compare with its direct rivals and the 7200.11 on which it's based? Read on to find out.
