The implementation of RAID 10 requires four drives. Performance is provided through the use of Striping (RAID 0), while adding the fault tolerance of Mirroring (RAID 1). This method should cause a decrease in writing speeds, and results in a disk capacity equivalent to that of the smaller disk RAID 10 (Striped & Mirrored) RAID 10 combines the features of both RAID 0 and RAID 1. A RAID 1 system can be recovered by simply replacing the damaged disk and mirroring the data on the new drive. If either of these drives should fail, no information is lost as the second drive will always contain an identical copy of the other. of 30ĥ 1.3.2 RAID 1 (Mirrored) RAID 1 works by maintaining an identical copy of the data of one drive on another. It is also fairly efficient in using disk space, with its size is equal to the size of the smallest disk multiplied by the number of disks. It does however, have vast improvements in both reading and writing speeds, with the theoretical speed proportional to the number of disks used in the array.
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. This guide was designed to only cover the basic operations in setting up RAID.
