NTFS performs faster than FAT32 partitions when doing anything but a search from EXPLORER. That has everything to do with the way NTFS searches for a file within EXPLORER, not because NTFS is less efficient. The organization is plain and simple a more efficient lay out. The secret to this efficiency lay in the huge index of files that is pre-sorted upon creation of the partition. The index of an NTFS partition is the same size before and after files fill up the partition. The FAT32 partition's index is smaller than a NTFS partition's index because the latter stores information on security, encryption, etc. The FAT32 partition uses an indexing system that grows as the drive fills, and therefore is less organized. You get a somewhat larger capacity because the index is smaller than the one used by NTFS. Whitedog, what don't you understand about this?
