How do I check RAID failure?

Symptoms of RAID failures are closely related to symptoms of the hard drive failure that are used in the RAID array. The chances of a RAID server failure can be easily analyzed by checking the condition and performance of the associated RAID disks by using an open-source tool like CrystalDiskInfo.

What happens if RAID fails?

If your RAID controller fails, your data may or may not be accessible, even if there is no damage to the hard drive’s magnetic platters – it all depends on the level of RAID. For example, RAID 0 or ‘striping’ distributes data equally across all disks in the array, meaning that even if one disk fails, your data is lost.
