On a side note, FAT32 is actually DOS. It showed up in Windows 95b and wasn't supported in NT until Win2K. I guess, what I have been trying to say, is that we all know it all comes down to disk I/O at some point. Reducing the number of sequencial disk I/O operations for each transaction will improve performence. Maybe choosing a simple file system will accomplish this.
