RE: NTFS or FAT32 for an external drive?
although that table is a nice and rough comparisson, it has some errors...
In theory, FAT32 volumes can be about 8 terabytes; however, the maximum FAT32 volume size that Windows XP and the likes can format is 32 GB. Therefore, you must use NTFS to format volumes larger than 32 GB. However, Windows XP and the likes can read and write to larger FAT32 volumes formatted by other operating systems.
For FAT32:
Maximum file size: 4 GB minus 1 byte (2^32 bytes minus 1 byte)
Maximum volume size: 32 GB
Files per volume: 4,177,920
Maximum number of files and subfolders within a single folder: 65,534 (The use of long file names can significantly reduce the number of available files and subfolders within a folder!!)
For NFTS:
Maximum file size (in theory): 16 exabytes minus 1 KB (2^64 bytes minus 1 KB)
Maximum file size (in practice): 16 terabytes minus 64 KB (2^44 bytes minus 64 KB)
Maximum volume size (in theory): 2^64 clusters minus 1 cluster
Maximum volume size (in practice): 2^56 terabytes minus 64 KB ( 2^32 clusters minus 1 cluster)
Files per volume: 4,294,967,295 (2^32 minus 1 file)
