ZFS differs from other file systems because it integrates a volume manager to control the storage hardware attached to a computer. HFS, HFS and APFS are not natively supported by Windows, Linux or other non-Apple operating systems. In 2017 Apple introduced a new file system called APFS or the Apple File System, which is optimized for SSDs and other solid state media. This edition added journaling and has a maximum file size and volume size of eight exabytes (when using Mac OS 10.4 or above). It offers a maximum file size of two gigabytes and a maximum volume size of two terabytes. Neither Windows or Mac OS has a native ext2 ext3 or ext4 support. In 2008 the ext4 was introduced which is the most modern dedicated Linux file system. In 1993 an update called Extended File System 2 or ext2 was then released and was for many years the default file system in many Linux distros. Many Linux systems require extra drivers to be installed to access exFAT devices. It has read and write support on Mac OS and recent versions of Android. In terms of compatibility, exFAT enjoys wider non-Windows support than NTFS. The maximum file size is 16 exabytes or effectively unlimited, which makes exFAT the best choice for formatting memory cards.įor this reason exFAT has been adopted by the SD card Association as the default file system for SDXC memory cards. The only real downside of NTFS is a lack of compatibility with older versions of Windows and non-Windows operating systems.įor example, by default NTFS volumes are read-only in Mac OS and in older Linux distros, and may not be readable at all on other devices such as standalone media players. NTFS also supports file permissions, file encryption and other features that make NTFS more suitable than a FAT32.įor these reasons all modern versions of Windows must be installed on a drive which is NTFS formatted. NTFS is also a journaling file system which means that it maintains a record of changes, so it can recover following a system crash or power failure.
It was introduced in 1993 to overcome the limitations of FAT32 and has a file size limit of 16 exabytes (an exabyte is 1 million terabytes, so in practice with no file size constraint).
Each FAT variant can divide a drive into an increasing number of clusters and supports an increasing maximum file size and volume size.įor example FAT12 supported a maximum file and volume size of 32 megabytes, meanwhile FAT32 can store individual files up to 4 gigabytes in size and is limited to 32 gigabyte volumes if formatted in Windows, up to 2 terabytes when formatted with other operating systems, and has an absolute maximum volume size of 16 terabytes.
