RAID (Redundant Array of Independent Disks) permit the end users to have more space for the user by utilizing multiple disks. It is very common to bump into difficulties when recovering data, which makes it essential to require the services of RAID recovery. There are two forms of RAID; there is the hardware RAID and the software RAID. Right before you try out the other recovery methods, it is advised that you get to differentiate the Hardware RAID from the Software RAID and get to understand their similarities. These two have both their advantages and disadvantages.
Hardware RAID versus Software RAID
The possibility of the Hardware RAID is because of the controller. The controller is a device that functions excellently that even if there is a failure in power, the RAID recovery is still possible. This equipment is one the factors that make this option very expensive compared to the cost of acquiring the Software RAID.
The Software RAID, on the other hand, depends solely on utilizing the Central Processing Unit. It shares the CPU with other processes at the same time, this is the reason its performance is no match to the Hardware RAID. One of the advantages of this option is that it is affordable and it does not require any additional equipment to function.
Types of RAID arrays
There are various types of the array for RAID. Each of the array types has its own unique requirement for RAID recovery. Below you will find two classifications:
RAID 0 array
A RAID 0 array is the type that utilizes two disk drives at the same time. One of the examples of this array type is two drives that contain a memory of 100GB each. At any instance when the 200GB logical volume of the array type experience any failure, the need for a data recovery is important. RAID recovery will ensure that the data is recovered and useful once again.
Raid 1 array
This array type, on the other hand, is in some form similar to that of RAID 0 array mentioned earlier, but the difference is in the fact that RAID 1 makes a copy of the information on the first drive to the second drive, therefore recovery is easy when there is some sort of failure.
