Tulihan tuota joskus testailtua, mutta mitää yleispätevää sääntöä en kyllä keksinyt eikä eroja ollut helppo havaita käytännössä. Näin mutuna voisi heittää että mitä isompi sen parempi, mutta aivan näin yksioikoinen asia ei ole.
 
Tässä pieni teksinpätkä asiaan liittyen.

"Formatting
 
When formatting your your hard discs, it is worth knowing that the cluster size can play an important part in the overall efficiency of disc performance (I/O).
 
Data from hard discs is read one cluster (allocation unit) at a time. This would mean that a disc with 4KB clusters would read 4KB at a time. Therefore, a 128KB file would require 32 separate discs I/O's. If the same file was stored on a disc that had been formatted with 64KB clusters, then only 2 discs I/O's would be necessary.
 
This is a very general and simplistic explanation of cluster sizes, but as a general rule of thumb if you plan to store many "smaller" files on a hard disc (your system discs), then it is probably better to let XP automatically determine the best cluster size for the disc. On the other hand, your audio disc will probably have fewer "larger" files (WAV files, typically 10MB per minute for stereo 16bit 44.1khz), so it may be better to increase the cluster size and override the assumption that XP makes when formatting.
 
There are other factors that need to be considered when deciding upon cluster size, so I suggest that you do a search on the internet for further information, and then experiment with your cluster sizes yourself, to find the best setting for your setup.
 
You may not find the disc performance differences associated with different cluster sizes earth-shattering (if at all), but I believe that everything, however small, can make a difference. "
