We have been testing some new products on the GIGABYTE P55A-UD4 lately and put the ASUS P6T7 WS SuperComputer on the shelf for a little while. The P55A-UD4 features USB 3.0 and SATA 6G so we were able to test both the Seagate Barracuda XT and Western Digital Caviar Black on the Intel SATA 3G and Marvel SATA 6G ports. Both drives have 2TB of capacity and are sold at the same 299.99 USD price.


If you are comparing our benchmark numbers to those of other sites, please be aware that several companies are pushing for storage products to be tested with a policy change that is found in device manager under each hard drive. The option, "Turn off Windows write-cache buffer on the device" will give you a small performance increase when the box is checked, but we feel it is dangerous since if you have a power outage all of the data in the hard drive's cache will be lost. Most users do not even know about the enhancement and we are trying to test drive performance as you, the user would see it.
