RAID0 stripes. Figure 1. Stripes organization on RAID 0 (2 units). Figure 1 shows data striping  What happens if you have a two-drive RAID 0 (striped), and then you mirror (with RAID 1) that array onto another pair of drives?

RAID 1+0, 0+1, 10: Some adapters combine (referred to as nesting) RAID 0 and RAID 1 to provide both data redundancy and increased disk performance. This works by either striping data across a pair RAID 10 is a striped (RAID 0) array whose segments are mirrored (RAID 1). This mode is a popular configuration for environments where high performance and security are required.

You may understand the data organization of the 2 RAID arrays from the following picture.--image from .wikimedia.org RAID 0+1 (01): Disk 1 + 2 + 3 are striped to create a RAID 0 array, and then disks 4 + 5 + 6 to create RAID 1 redundancy. With RAID 0+1, a single disk loss from one side of the array (1,2,3 or 4,5,6) will degrade the array to a state where you are essentially running RAID 0 (which is bad).

This can be used in organizations where high performance and security are required. In terms of fault Tolerance and rebuild performance it is better than 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. 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. 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 0 offers no redundancy and instead uses striping, i.e., data is split across all the drives.

blank. RAID 0 (STRIPE) RAID 0 splits data across drives, resulting in higher data throughput. The performance of this configuration is extremely high, but a loss of any drive in the array will result in data 2020-12-01 RAID 2 This uses bit level striping.
