3. 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.
4. 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.
5. 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
6. It consist of minimum 4 drives.
Single dedicated parity disk. Disk
failure has an insignificant
impact on throughput.
Preferred for reading video files.
7. 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.
8. 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.
9. 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
10. 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.
