There are obvious differences between a RAID array and a hard disk drive. A RAID array is a logical unit used for data redundancy or performance improvement by distributing data across multiple drives using parity, an error protection scheme.

Applying proper data recovery techniques is the best way to avoid the loss of important information. RAID stands for the redundant array of independent discs, which is a server system that functions with multiple hard drives.

There are many different RAID array levels and each level has tasks for which it is most suited. The RAID level you choose for your system depends on the amount of storage you require, the way you need to access your data and other outside factors such as cost, preferences and other considerations.

The decision to use data recovery software versus the professional service of a data recovery company is one that should be weighed carefully.
