Access Time
Our Western Digital 74 GB entry beats the other Raptors (except the Raptor 150) and shares the title for new king of the heap - it has the best performance this side of a solid state drive. The score of the Barracuda ES is down the way a bit, and is almost identical to that of its 750 GB "cousin", the Seagate 7200.10.
Interface Transfer Rate
The Barracuda scores higher running SATA/300 and the SATA/150 Raptor significantly less. As we'll see in tests applied to real world numbers, though, interface bandwidth does not necessarily correspond to higher performance at all.
