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
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
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
