The Seagate Barracuda XT 3TB is the fastest mechanical drive that we have tested. The drive has excellent sequential read and write up to 150MB/s. While SSDs may grab the market headlines, they are still relatively expensive at $1.5 per gigabyte and with capacity limited to a few hundred gigabytes. At 0.08 cents per gigabyte, the Seagate Barracuda XT offers an excellent pricing as a secondary drive to complement the limited storage capacity of the SSD. With 3TB of space, 64MB Cache, 7200 RPM and SATA 6Gb/s interface, the Barracuda XT 3TB definitely won't bog down a system. It is also hard to say no to the drive considering that it comes with a 5 year warranty, while most mainstream hard drives now only carry 3 year warranty.
