- Fujitsu 40GB / 8MB cache / 5400RPM (MHV2040AH)
- Western Digital 60GB / 2MB / 5400RPM (WD600UE)

When a read command arrives at the hard drive, the drive first checks to see whether the requested data is in the cache. If the cache does not contain the requested data, the drive retrieves the data from the disk. Solid-state cache memory is thousands of times faster than the spinning platter of a hard drive.

A large cache will significantly impact performance. Most new drives have at least 2MB of cache memory, while some newer drives have up to 8MB of cache memory which helps to deliver a tremendous performance increase over older drives with as little as 512KB of cache memory.

Transfer Rate
ATA/133 is available from some manufacturers, but is it money well spent? Consider the sustained versus the burst transfer rate.

Sustained vs. Burst Transfer Rates
Sustained transfers refer to a continued transfer that does not occur from the drive cache. Burst rates refer to data transferred directly to/from the high speed cache. A true indicator of performance is sustained rate; however, most drives are advertised with their faster burst rate.

A typical ATA/100 hard drive bursts at about 100MB/sec from the cache, but has a sustained rate of about 26-42MB/sec, depending on the drive.

If you consider a best-case scenario with the 2MB cache full of data, 100MB/sec will quickly deplete the cache and commence transferring at the lower sustained rate.
