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 1 + 0 through a HW controller for the first layer and mobo for the second layer would technically show you as having 2 disks since the RAID card would only show 2 to the motherboard which would then combine those two, therefore you would only see 2 drives unless you opened up the computer itself.

RAID 0+1. A RAID 1+0 array is implemented as RAID 0, whose elements are RAID 1. It combines the same advantages of RAID 0 (speed) and RAID 1 (safety), but in different way. RAID 1+0 creates a large stripe of small mirrors. After failure of a disk, while it is being replaced, only …

raid 01 (raid 0+1) Массив raid 01 (raid 0+1) называют «зеркалом страйпов». Он представляет собой массив типа raid 1, состоящий из двух вложенных массивов типа raid 0.

In a two-disk RAID 0 array, the data of the first, third, fifth blocks will be written to the first disk, while the second, fourth, sixth blocks will be written to the second disk. With this data organization, the entire RAID 0 array will fail once one of the disks crashes. However, RAID 1 array differs from RAID 0.

RAID Level 0, 1 und 0+1. Bei RAID Level 0 handelt es sich - wie die Null im Namen schon andeutet - um kein redundantes Speicherverfahren. Es dient lediglich zur Beschleunigung von Plattenzugriffen. Dazu fasst RAID 0 zwei oder mehr Festplatten zu einem logischen Laufwerk zusammen. RAID 10 kan være forskellige ting: Linux' RAID driver har et RAID10 modul, der minder om RAID 1+0, men som kan køre med blot 2 diske, kan bruge et ulige antal diske, kan fordele data på forskellige måder og har en lidt anden ydelsesprofil, bl.a. læsehastighed som RAID0.

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? You'd have a mirrored RAID 0, (Exempel på det är till exempel RAID 1+0, även känt som RAID 10.) RAID 2 och 3 fungerar på samma sätt fast med checksumma per bit respektive byte i stället Det kan exempelvis vara Raid 1, Raid 5, Raid 6, eller Raid 1+0.

RAID 2 This uses bit level striping. i.e Instead of striping the blocks across the disks, it stripes the bits across the disks. In the above diagram b1, b2, b3 are bits. E1, E2, E3 are error correction codes. You need two groups of disks. One group of disks are used to write the data, another group

RAID 0 offers no redundancy and instead uses striping, i.e., data is split across all the drives.

RAID 10 combines RAID 0 and RAID 1 with a minimum of four (4) disks. In RAID 10, two (2) disks are striped and mirrored onto two (2) other disks, creating a single array of disk drives. Such a configuration benefits from RAID 0’s high performance and RAID 1’s fault-tolerance. RAID 0+1 is often interchanged for RAID 10 (which is RAID 1+0), but the two are not same.
