Windows 8 official blog details the storage space management of the new operating system. In Windows 8, the "Storage Spaces" function is introduced. physical disks are centrally managed in pools. Storage pools can be divided into different Spaces and formatted, such as ordinary hard disks for daily use.


Similar to Solaris's ZFS and Linux's btrfs, the storage pool can use disks with different interface technologies-USB, SATA, and Serial Attached SCSI. New disks can be added to the pool at any time. The pool can contain one or more hot backup disks. The storage space in the Pool provides three fault tolerance redundancy policies: two-way images, three-way images, and RAID 5-like parity.

Depending on the Image Selection, data in one space is stored 2 to 3 times in the pool. If you select parity check, the system calculates additional information and stores it in the pool. If any disk fails, the data can be used to reconstruct the data. Win 8's new storage management technology is more advanced than Windows Home Server's Drive Extender.
