The term RAID stands for Redundant Array of Inexpensive Drives, and the three main types of RAID include RAID-0, RAID-1, and RAID-5. If there is a problem in a RAID, then it is always better to contact a professional to avoid data loss. There are various reasons RAID failure occurs, such as RAID controller failure, virus damage, a configuration is lost, multiple drives failure, and many other reasons. However, the failure can become worse if you think that you can handle any error in RAID yourself. Therefore, experts always suggest not poking your nose into the matter if you don’t know about it, and just take the RAID to a professional RAID technician.
Professional RAID engineers evaluate RAID and recover the data, and their first priority is always to recover the data. These technicians find RAID array problems such as either RAID has suffered some physical damage or a logical corruption. These technicians can handle both these problems in RAID. So, why don’t people want to use the services of a technician for RAID recovery? The reason is very straightforward - and that is the huge costs that these professionals charge. The fee charges for RAID recovery can start from $1500, and the cost can also vary depending upon number of hard disks in the arrays, the type of RAID, size of disk and the reason for failure. It becomes very difficult for the average person to spend this amount for mail recovery, RAID recovery, hard drive recovery or any other form - but I think it is necessary to go to a certified expert for this, because after all, data is worth more than the charges incurred to recover it.
