NTFS
NTFS allocates space in terms of clusters, which in theory may range from 0.5KiB to 128KiB in size, just as for FAT. NTFS uses 64-bit fields to store cluster numbers. So the theoretical maximum size of an NTFS volume, with the largest possible cluster size (which is, as for FAT, ridiculously large and inefficient), is 4ZiB/4.61ZB.
In practice, the maximum size of an NTFS volume is much lower, because Microsoft's NTFS drivers in Windows NT use 32-bit numbers for cluster numbers, not 64-bit numbers, and only support cluster sizes up to 64KiB. This reduces the practical maximum size of an NTFS volume to 256TiB/281.5TB. As with HPFS, this is a coding flaw in one particular NTFS driver, not a limitation of the filesystem structure on disc.
From Windows NT version 3.51 onwards, the maximum cluster size (when new volumes are high level formatted) is further reduced to 4KiB, both because this is an efficient size for paging and because the NTFS file compression mechanism places this limit on cluster sizes, reducing the practical maximum size of an NTFS volume yet further to 16TiB/17.6TB.
依照此文,应该是每个"分区"最大16TB。 |
