We had two versions of Seagate's Barracuda 7200.7 for testing purposes. Unlike Seagate's advertising slogans regarding the good performance of this model, it won't be able to keep up with the two Western Digital Raptor drives - not even with Command Queuing. The reason is the slower rotation speed of Seagate's Barracuda 7200.7. Yet, all Seagate drives are still worth paying for because of their comfortably low noise level.
