Quite a few people have called and asked about our RAID recovery services. There are several questions that are asked frequently, so I’ll try to answer them without getting too technical.

• What does RAID mean? It looks like an acronym. o RAID stands for redundant array of independent disks, or according to some, redundant array of inexpensive disks. Whichever one you want to use, a RAID array is made up of several hard drives that are connected together to act as one big drive. The array is usually formed by attaching the disks to a hardware drive controller; even so, there are software controllers as well. • What is the purpose of a RAID array? o The most common use of a RAID array is in a business server. A server store files from multiple users and may also be serving many computers with a common program, such as a database. RAID arrays can hold large quantities of data. Additionally, RAID arrays can be configured to provide data redundancy. This stores multiple copies of the same file, ensuring data integrity in the event of a failure. • Are RAID systems more difficult to recover when data loss happens? o The process of RAID data recovery is quite a bit more involved than recovery from a single drive on a PC. To be successful, all of the disks in the RAID array must be sent to the recovery lab together, along with documentation about their configuration. I’ll be answering some more questions in – Part Two.
