Windows 8 includes a storage scheme suitable for business deployment that can treat hundreds of disks as a single logical storage reservoir and ensures resiliency by backing up data on at least two physical disks.



From Computerworld:

Pools are treated as single virtual disks that can be partitioned and formatted as if they are single physical disks, according to the Microsoft Building Windows 8 blog. Spaces are defined across multiple physical disks, and the physical disks can still be treated as one even if they vary in size or are connected via different interfaces such as USB, Serial ATA (SATA) or serial attached SCSI (SAS).
