Line 21:
Amiga stores 880 [[kibibyte|KiB]] on a DD disk and 1760 KiB on an HD floppy disk.
 
The standard Amiga filesystem has an internal 32 bit wide offset parameter (unsigned). It tells where to start the read/write operation. The biggest size for an Amiga disk is therefore 2<sup>32</sup> = 4 [[gibibyte|GiB]]. This limit was changed with Amiga OS 3.5 and 3.9 and now is 2<sup>64</sup> = 4 [[exabyteexbibyte|EiB]].
 
OFS Datablock stores Block Size BSIZE-24 bytes (i.e. normally 488 bytes at most frequently used BSIZE of 512 bytes), FFS stores BSIZE bytes (512 bytes per block).
