In RAID 0 (Stripping) data safety and access speed are also increased by joining several disks in a group. However, the data blocks are not processed in a linear fashion, but in parallel on the various hard disks. To do so, the data block is evenly distributed among the hard disks. However, if one hard disks fails under RAID 0, there is always data loss.
(data striping) - file blocks are written to separate drives. Does not provide fault tolerance, because failure of one drive will result in data loss.
Redundant Array of Inexpensive Disks – non-redundant striped array. Technically there is no redundancy at this level, but it does provide for speed advantages, compared with a single disk drive, by striping data in parallel sectors across multiple disk drives. The I/O transfer speed is increased for this architecture, however, a single drive element failure can result in an irrecoverable data loss. See also RAID.
Redundant Array of Independent Disks (level 0). A set of protocols by which multiple hard drives are connected together for increased performance and/or data protection. RAID 0 enables data-striping for faster throughput, but doesn't provide for any type of data protection. Conversely, RAID 1 enables disk mirroring, which duplicates data on a second hard disk for constant backup purposes. (4/99)
Striping. No redundancy. Fastest. Provides maximum storage. No fault tolerance.
Non-redundant striped array: drives are accessed alternatively, as of stacked one on top of the other.
Striping. 2 or more drives, striped with no mirroring or parity. Very fast.
Block striping across multiple drives is provided, yielding higher performance than is possible with individual drives. This level does not provide redundancy.
Protects data with "striping", dividing data into blocks and distributing them across several hard disks.
Also known as disk striping, this form of RAID combines two or more hard drives into a single logical drive. Any data is written in blocks first to one...
Utilizes a data striping method by splitting information amongst the array of drives, but offers no redundancy although it does improve performance.
RAID 0 implements block striping where data is broken into logical blocks and striped across several drives. Although called RAID 0, this is not a true implementation of RAID because there is no facility for redundancy. In the event of a disk failure, data is lost. In block striping, the total disk capacity is equivalent to the sum of the capacities of all drives in the array. This combination of drives appears to the system as a single logical drive. RAID 0 provides the highest performance without redundancy. It is fast because data can be simultaneously transferred to/from multiple disks. Furthermore, read/writes to different drives can be processed concurrently.
Also known as data striping, RAID 0 functionality divides data into blocks and distributes the blocks across multiple disks in a array. Distributing the disk I/O load across disks and controllers improves disk I/O performance. However, striping decreases availability because one disk failure makes the entire disk array unavailable.
A RAID 0 (also known as a striped set) splits data evenly across two or more disks with no parity information for redundancy. RAID 0 is normally used to increase performance, although it can also be used as a way to create a small number of large virtual disks out of a large number of small physical ones.
