A RAID recovery is typically more complex than a single drive recovery due its advanced hard drive configuration system. RAIDs are composed of two drives or more, that are designed to facilitate redundancy (also known as fault tolerance) by distributing data across multiple hard drives. This redundancy is crucial for data protection and is designed to protect users’ data if one hard drive fails.
Although they are designed to expedite data access and prevent data loss, even RAIDs are subject to failure. Common RAID failures include problems originating in the controller, RAID rebuild errors, loss of configuration settings to the server, server registry configuration loss, accidental replacement of media components, and physical hard drive failure(s) within the unit. Therefore, it is important not to mistakenly substitute RAIDs for proper and regular back-up practices.
ReStoring Data’s award-winning team is the industry leader in recovering from any RAID, regardless of the number of drives, file system, or configuration. We offer the industry’s highest RAID recovery success rate!
The most common RAID configurations that are routinely handled in our fully equipped, class-100 clean room data recovery lab are:
RAID 0: Data is striped across multiple hard drives. This configuration provides the utmost speed. The main drawback of this system is its lack of redundancy. We specialize in RAID 0 recovery.
RAID 1: Data is written to and read on both hard drives simultaneously (drives are mirrored). Because the data is identical on both drives, we normally treat RAID 1 recoveries as a single drive recovery. We specialize in RAID 1 recovery.
RAID 5: This type of RAID offers both data redundancy and faster performance. With this configuration, one drive can crash, and the data should remain intact. We specialize in RAID 5 recovery.
RAID 6: Like RAID 5, this RAID level provides distributed parity information, but it allows for two drives to fail while keeping the rest of the data intact. This configuration is normally presented in business-oriented/focused NAS units. We specialize in RAID 6 recovery.
RAID 10: This configuration combines RAID 1 and 0, so the data is stripped (RAID 0) across mirrored/identical pairs (RAID 1) of drives. We specialize in RAID 10 recovery.
RAID 0 + 1: This configuration is opposite to RAID 10; the data is identical on both stripped pairs of drives. We specialize in RAID 0 +1 recovery.
