RAID 0 does not protect data from failure, and due to the way it stores data, a fault on one drive would result in failure of the entire array. Silicon Image Sil3114 SATARaid provides support for four RAID Set types: Striped (RAID 0), Mirrored (RAID 1), Mirrored/Striped (RAID 10) and Parity RAID (RAID 5 by SATARAID5 software) RAID 0 (Striped) RAID 0 works by breaking down data and spreading it over multiple disk drives. 1.3 Different Types of RAID Configurations Raid levels or set types are given a numerical designator that defines its implementation. There are ways however, to minimize this effect, even making it more reliable than using single disks. This results in a greater chance of losing the information on your disks. The probability of a single drive failing out of many drives is much higher than that of one failing out of only one. However, since multiple drives are used, data can be stored in such a way that it spans over many disks, thus the information can be accessed by the disks simultaneously, significantly improving data access times Disadvantages of RAID Using many drives has a disadvantage. There are many different methods of implementation for RAID, with each having advantages and disadvantages Advantages of RAID The obvious advantage of using a RAID configuration is the ability to create drives with larger capacity. 1.2 The Basics What is RAID? RAID Technology manages multiple disk drives to enhance I/O performance and provide redundancy in order to withstand the failure of any individual member, without the loss of data.
