More cache for WD Raptor

Western Digital's line of enterprise class hard drives have been favorites of enthusiasts since the first 36GB model was introduced and it still takes the crown in performance in both standalone and RAID configurations.

Western Digital silently updated two of its Raptor series drives: the 36GB WD360ADFD and 74GB WD740ADFD 10,000RPM models have been blessed with doubled buffers to 16MB each. The performance specifications have improved over the 8MB cache models along with a slight increase in power consumption. The new models also add Native Command Queuing to the list of features, a change from the older Tagged Command Queuing method.

Among the performance updates are increases in 'Buffer To Disk' sustained transfer rates of 84MB/sec up from the previous models' 72MB/sec as well as lower overall average seek times. The updated 36GB and 74GB Raptor models are also 3 dBA quieter in the idle state.  However, both drives still carry a SATA 1.5Gbps throughput rating.

These updated models are not shipping yet, but retails tell us the drives should appear within the next few days.  Interestingly enough, the new models come just hours after Western Digital cleared up its customer loyalty program with DailyTech
