A typical hard disk and Raid hard drive differ in the way their functions. Main objective of RAID for data redundancy and to have a better performance. More redundancy, more performance. RAID stands for Redundant Array of Independent Disks, originally known as cheap disk name.
The functionality is performed by the technique of combining multiple drives into a single logical component. The need for data redundancy and performance depends on the case. So there are certain levels how data redundancy and performance is affected. There are a number of RAID mechanisms to better serve the objective. RAID 0 is the least tolerant and redundant RAID 6 while two error correction levels.
Depending on the number of RAID, the difficulty or ease of data recovery procedure can be modified. If a disk fails in a RAID 0 drives, then all drives fail and no data recovery possible. It is essentially a mechanism for using a plurality of data storage locations via parity.
RAID mechanism can be seen in the two sections depending on the nature of the next RAID in addition to the RAID numbers. There are two hardware RAID and software RAID
Differences between Hard Raid and Software Raid
Hardware RAID
Hardware RAID means a mechanism based on the material. The equipment is designed and included in order to satisfy the RAID mechanism. It can be performed by means of a RAID-system board or be integrated into the motherboard itself. In this kind of individual drives technology are used, but the system has all the same disc. The resulting capacity RAID disk depends on the number of units, and the RAID level. Usually, the number of RAID, plus the ability resulting from the disk, because a lot of space for parity and make data recovery much easier than the previous level. For example, if the same number of disks with the same capacity is used RAID 0, the resulting capacity will be higher than when they are used in a RAID 6 disk.
Software RAID
RAID software, such as name, is caused by software and there is no need for equipment initially configured for RAID drive. In a computer, there are tools such as Device Manager for each component to better manage hardware. The software and programming are now so advanced that we can actually manipulate hardware functions through advanced software. Software RAID is achieved by the distribution of zones in different disks to form a RAID virtual disk. The computer will then recognize all areas combined as a single disc or drive. In the operation of the computer, all components of the impact of the software are combined a.
