Seagate today launched a Barracuda XT HDD which features 2TB of storage and 64Mb of cache, which is the highest we have ever seen on a traditional Hard Disk. Solid State Drive’s are known to come with high amount of cache, with some even coming with up to 256MB of cache. What sets this Seagate Barracuda XT HDD aside from any other HDD on the market aside from the high amount of cache is that the drive comes with Sata 600 interface or popularly known as SATA 3.0. The Seagate Barracuda XT is the first hard disk on the market to feature SATA 3.0 interface. The Model number of the drive is ST32000641AS and costs 299$.
Even though this drive is the first in the market to support SATA 3.0 interface, it is totally useless as officially as of now only the Asus P7P55D supports the SATA 600 interface. Add this to the fact that Traditional HDD’s won’t be able to take advantage of the higher band with offered by the SATA 3.0 interface and the interface advantage of this drive almost seems useless except for the bragging power. Unless something radical happens, traditional HDD’s won’t be able to limit the bandwith offered by SATA 2.0, forget SATA 3.0. Only Solid State Drives have been able to saturate the bandwith offered by SATA 2.0, so it is more than obvious that SSD’s will definitely benefit from the use of SATA 600 interface.
