The maximum NTFS volume size implemented in Windows XP Professional is 2 32 − 1 clusters, partly due to partition table limitations. For example, using 64 KB clusters, the maximum size Windows XP NTFS volume is 256 TB minus 64 KB. Using the default cluster size of 4 KB, the maximum NTFS volume size is 16 TB minus 4 KB.

Since the Volume Bitmap must have a bit to represent each allocation block, its size is determined by the size of the volume itself. [2] The Extent Overflow File is a B-tree that contains extra extents that record which allocation blocks are allocated to which files, once the initial three extents in the Catalog File are used up. Later versions ...
File Allocation Table (FAT) is a file system developed for personal computers and was the default filesystem for the MS-DOS and Windows 9x operating systems. [citation needed] Originally developed in 1977 for use on floppy disks, it was adapted for use on hard disks and other devices.
In computer file systems, a cluster (sometimes also called allocation unit or block) is a unit of disk space allocation for files and directories.To reduce the overhead of managing on-disk data structures, the filesystem does not allocate individual disk sectors by default, but contiguous groups of sectors, called clusters.
This partition is used by Mac OS for the Macintosh File System (MFS), which was introduced with the Macintosh 128K in 1984. Apple_partition_map: partition map: Apple: The partition map is also a partition of its own. It can vary in size depending on how many partitions it may contain.

For a 512-byte allocation, the average unused space is 256 bytes. For 64 KB clusters, the average unused space is 32 KB. Generally, the allocation unit size is set when the storage is configured. Choosing a relatively small size compared to the files stored, results in excessive access overhead.
For hard disks with 512‑byte sectors, the MBR partition table entries allow a maximum size of 2 TiB (2³² × 512‑bytes) or 2.20 TB (2.20 × 10¹² bytes). [ 1 ] In the late 1990s, Intel developed a new partition table format as part of what eventually became the Unified Extensible Firmware Interface (UEFI).
