Online array reconstruction / reassemble, in a fraction of the time usually required to reconstruct an array, thanks to reconstruction dependent on contents rather than on disk topology.

Elimination of the RAID5 write hole that usually requires battery-powered disk technology or UPS technology to keep RAID arrays consistent in case of power failures.

State-of-the-art unsurpassed data reliability (including silent corruption detection and automatic data repair, if available) from end to end, thanks to transparent checksums in parent block pointers Along with its record-setting scalability, it has a number of features that no other file system in production has: ZFS is 128-bit, meaning it is very scalable. Compression can be used to increase bandwidth. The available disks (of any size) are used to the best of their ability.

ZFS does away with partitioning, EVMS, LVM, MD, etc. ZFS is a killer-app for Solaris, as it allows straightforward administration of a pool of disks, while giving intelligent performance and data integrity.
