The data block is
subdivided ("striped") and written on the
data disks. Stripe parity is generated on
writes, recorded on the parity disk and
checked on reads.
RAID Level 3 requires
a minimum of 3 drives to implement. RAID 3
is highly efficient and single disk failure
affects performance only slightly. In certain
instances a RAID 3 array can recover from multiple and simultaneous hard drive
failure. It is commonly used for
applications with very high throughput, such
as video production, live streaming, and
video editing. Read and write speed is
high.
Because data on
a RAID array or volume is typically critical
to business continuity, when it becomes
inaccessible due to one or more hard drives
failing, a bad RAID controller, failed
upgrade or damaged striping, it is
imperative that you shut the server down and
get expert help!
Permanent loss of data
often occurs when hard drives are swapped,
moved from one position to another or placed
in other machines in an attempt to rebuild
or repair the array. Formatting a boot drive
or partition can also damage or remove
striping reducing recoverability of data and
causing permanent loss.
The RAID 3 data
recovery technicians at American Data
Recovery, Inc. can rebuild failed hard
drives, repair damaged RAID volumes and
recover data your company needs if you call
before the damage is too severe. Once
platters are damaged, striping overwritten
or changed completely, the chances of
getting your data back are slim.
- Raid controller
failure or configuration changed
- Two or more hard
drives fail or go offline
- Server crashes and
won't remount the array or volume(s)
- Configuration becomes
corrupt or damaged
- Adding incompatible
drives
- Hardware
conflicts
- Software corruption
- Virus infection,
software and operating system upgrades
