About RAID

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.

LEVELS OF RAID

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.

RAID 1

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

RAID 3

It consist of minimum 4 drives.

Single dedicated parity disk. Disk failure has an insignificant impact on throughput.

Preferred for reading video files.

RAID 5

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.

Reasons of Raid Failure

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.

In Order To Avoid Worse Stage In Raid Failure Following Steps Should Be Taken

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

Conclusion

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.
