A few months ago, we evaluated the 1-terabyte (TB) Seagate Barracuda 7200.11 SATA hard drive and found the drive to offer many positive features in addition to its massive capacity. In this article though, we'll be looking at Seagate's new flagship enterprise-class, mass storage solution, the 1TB Barracuda ES.2. While the Barracuda 7200.11 and ES.2 are almost identical drives, there are some important differences to highlight between them. For instance, the 7200.11 has a mean time between failure (MTBF) rating of 750,000 hours while the ES.2 boasts a superior and more server-oriented MTBF of 1.2 million hours. Essentially, this means the ES.2 should be a more reliable drive that is less likely to fail.
