- No, the Amiga FileSystem is slower too. On an Amiga a directory is stored as a
- hash-table with pointers to other disk-blocks for each file. So when the
- directory is scanned, the diskdrive head has to jump to and fro to about every
- corner of the disk to get information about size, name, bits etc. FFS provides a
- (simple) solution, it also keeps a table. Most floppies are still OFS formatted
- though.
-
- On the PC however, all is kept in tables, the well-known FAT's. This makes disk
- accessing a lot faster (compare a CrossDOS disk to an OFS one).
-
- Of course, on the Amiga we just install another FileSystem if we are not
- satisfied by the old one. We can boot from it, read/write it, mount/dismount it
- if we want, use it on every disk-type we like (from ram-disk to floppy).
- Something like that on a PC? Don't make me laugh.
