Raid Data Recovery Basics

With the cost of hard disk falling, it is not uncommon for home desktop PCs to have RAID. In fact, most PC motherboards have a built-in RAID controller, even if it is not in use. RAID is short for “redundant array of inexpensive disks” and was developed to use smaller disks in an array for better performance, scalability, and data reliability and recovery.

RAID achieves all these aims via several configurations. The most common nowadays are RAID 0, RAID 1, RAID 0+1/ RAID 10 and RAID 5. Each of these RAID types has their own method of redundancy.

RAID 0 is simply striping the data across multiple disks. It’s like dividing the data into smaller pieces of fixed size, called the “stripe width,” and writing the stripes across the disks. If the file to be written was 5KB in size, with a stripe width of 1KB and there are 4 …
