PCSTATS will be testing out Seagate's 2TB, 6Gb/s SATA III Barracuda XT hard drive. This 3.5" desktop hard drive features an increased 64MB onboard cache where other 2TB drives only have 32MB and it supports Native Command Queing (NCQ). The Barracuda XT is the performance oriented drive in Seagate's stables, a spindle speed of 7200RPM gives it a healthy maximum sustained data rate of 138MB/s. The Seagate Barracuda XT being reviewed today uses Perpendicular Magnetic Recording technology and has a capacity of 2 TeraBytes (2,000 GB). Beneath its shiny metal exterior are four platters rotating at 7,200RPM.
