FAT 16 has a 2 GB per partition limit on all operating systems except for Windows NT where the limit goes up to 4 GB this is accomplished by increasing the cluster size to 64 k. FAT 32 it limited to 2 TB except for when used with Windows 2000 in which case it is limited to 4 TB. NTFS 1.0 through 5.0 is limited to 15 exabytes.
Here is a listing of byte sizes up to the yottabyte.
