Unfortunately except on RISC OS, where no use is made of free memory to 
cache filing system operations, as just about every other common OS does.

The closest RISC OS comes is some fixed size buffering an ADFS, which 
often resulted in the Risc PC's slow motherboard IDE interface 
outperforming much better 3rd party IDE hardware using IDEFS variants 
with no caching.
