HPFS (High Performance File System)

HPFS (High Performance File System) is the file system introduced with IBM’s OS/2 version 1.2. HPFS is noted for handling large file (2 gigabytes) across multiple hard disk volumes (addressable up to 2 terabytes) and long file names (up to 256 bytes). HPFS was designed to get around several limitations at the time in MS-DOS, among them its eight-character name restriction. HPFS uses a centrally-located root directory and B-tree lookup to speed access. HPFS can coexist with the MS-DOS file system, File Allocation Table (FAT), or run independently.

NTFS

NTFS (New Technology File System) is aproprietary file system developed by Microsoft. Starting with Windows NT 3.1, it is the default file system of Windows NT family.

NTFS has several technical improvements over FAT and HPFS (High Performance File System), the file systems that it superseded, such as improved support for metadata, and the use of advanced data structures to improve performance, reliability, and disk space utilization, plus additional extensions, such as security access control lists (ACL) and file system journaling.

Mac OS X kernels also have a limited ability to read NTFS; Linux and BSD kernels have a free and open-source driverfor the NTFS file system with both read and write functionality.
