- I believe that IBM recommends that you continue using FAT for small disks.
- I think the minimum recommended HPFS size is 60Mb.
-
- If you are looking for comparisions between HPFS and other file systems,
- you might want to hunt around the UC Berkeley for tech reports. The HPFS
- is very similar to the Fast File System the Berkeley developed for UNIX.
- Since grad schools tend to generate a lot of paper, I am sure you should be
- able to find information about file system performance.
