It's been my experience since beta testing Vista
that ReadyBoost works better when formatted using NTFS.
While Frank is basically correct, on smaller drives like 4GB,
FAT is generally faster. However, ReadyBoost will not produce
errors like you experienced when formatted with NTFS.
Also, don't expect much of a boost when you have 1GB
or more of RAM. Perhaps, under certain circumstances.
But, ReadyBoost is really meant for computers with
under 1GB RAM. Although, on my Vista machines with
2GB of RAM, I have noticed some performance boost using
ReadyBoost when I'm using virtual machines.
