Maximum Volume Size
In theory, the maximum NTFS volume size is 264−1 clusters. However, the maximum NTFS volume size as implemented in Windows XP Professional is 232−1 clusters. For example, using 64 KiB clusters, the maximum NTFS volume size is 256 TiB minus 64 KiB. Using the default cluster size of 4 KiB, the maximum NTFS volume size is 16 TiB minus 4 KiB. (Both of these are vastly higher than the 128 GiB limit lifted in Windows XP SP1.) Because partition tables on master boot record (MBR) disks only support partition sizes up to 2 TiB, dynamic or GPT volumes must be used to create bootable NTFS volumes over 2 TiB.
