   Diagram of a RAID 1 setup. RAID 1 consists of an exact copy (or mirror) of a set of data on two or more disks; a classic RAID 1 mirrored pair contains two disks.This configuration offers no parity, striping, or spanning of disk space across multiple disks, since the data is mirrored on all disks belonging to the array, and the array can only be as big as the smallest member disk.

   en.wikipedia.org/wiki/Nested_RAID_levels

   RAID 01, also called RAID 0+1, is a RAID level using a mirror of stripes, achieving both replication and sharing of data between disks. [3] The usable capacity of a RAID 01 array is the same as in a RAID 1 array made of the same drives, in which one half of the drives is used to mirror the other half.

   RAID (/ r eɪ d /; redundant array of inexpensive disks or redundant array of independent disks) [1] [2] is a data storage virtualization technology that combines multiple physical data storage components into one or more logical units for the purposes of data redundancy, performance improvement, or both.

5. Data striping - Wikipedia

   en.wikipedia.org/wiki/Data_striping

   In some RAID configurations, such as RAID 0, failure of a single member drive of the RAID array causes all stored data to be lost. In other RAID configurations, such as a RAID 5 that contains distributed parity and provides redundancy , if one member drive fails the data can be restored using the other drives in the array.

   The older "Intel Matrix RAID" is supported under Microsoft Windows XP. Linux supports Matrix RAID and Rapid Storage Technology (RST) through device mapper, with dmraid tool, for RAID 0, 1 and 10. And Linux MD RAID, with mdadm tool, for RAID 0, 1, 10, and 5. Set up of the RAID volumes must be done by using the ROM option in the Matrix Storage ...

   RAID support planned in 2.0 version [8] Apple: Mac OS X Lion: Core Storage: Yes [9] No No No No No No Currently, it is used in Lion's implementation of FileVault, in order to allow for full disk encryption, as well as Fusion Drive, which is merely a multi-PV LVG. Snapshots are handled by Time Machine; Software-based RAID is provided by ...
