Raid 
Recovery
Introduction 
Levels of Raid 
Reasons of Raid Failure 
Steps for Recovery 
Conclusion
RAID - Redundant Array of Independent Disks 
It consist of multiple disk for the greater 
storage and performances in long run. 
Performance of Raid depends upon different 
levels for e.g. Raid1 perform different from 
Raid3 and Raid 3 performs differently as 
compared to raid5 and so on.
RAID 0 
It consist of minimum two disk. 
No parity calculation is involved. 
Input/output performance increased by 
spreading Input/output load across the drives 
and channels.
It consists of exactly two drives. 
Fault tolerance is very good. 
Excellent redundancy 
No rebuild is necessary in case of a disk failure. Transfer 
rate per block is equal to that of a single disk
It consist of minimum 4 drives. 
Single dedicated parity disk. Disk 
failure has an insignificant 
impact on throughput. 
Preferred for reading video files.
It is the most popular level of 
technology. Minimum 3 disk 
required. 
It provides better performance 
than mirroring and fault tolerance. 
Highest read data transaction 
rate.
Raid data recovery is important in case of deletion 
or catastrophic failure. Catastrophic failure can be a 
human error and viruses in computer 
Power Outages is a common occurrence. Power 
failure leads to terminal loss of data. 
Raid failure can either in the form of hardware 
failure.
Remove the entire disks from the raid and label the cables, port and disks 
for further reassemble of raid. 
Create an image of the RAID member disks, to create an image, connect the disk 
to a non-RAID disk controller, such as a hard drive dock, a normal hard drive bay on 
your computer. 
Take a blank drive as a backup to accommodate the data you want to recover. 
A professional data recovery tool is always beneficial to build up raid 
virtually. 
Software sometimes are not able to recover complete data; in that case 
professional services are always up to the mark. The success rate is more in 
case of Raid recovery services. You can acquire Raid Data Recovery 
services http://www.stellarinfo.co.in/services/raid-data-recovery.php
Raid is a complex device in order to secure it 
necessary steps should be taken for the 
recovery. 
The chances of successful recovery are more in 
services that of software. If we take effective 
steps we will be able to build Raid again.
Thank You
