Linux RAID | RAID 1 RAID 5 | Data Recovery Service through Hard disk recovery and Easy Recovery

RAID – Redundant Array of Independent Disk or Redundant Array of Inexpensive Disk
Raid is a method of combining several physical disks into make virtual disk. It will provide
Data recovery services through implementing hard disk recovery or data recovery hard disk without using any file recovery software. So the Raid method is performing easy recovery operation.
These data recovery service for hard disk recovery if one disk get damaged the data can be recover from other disk and the function of the other disks does not get affected.

RAID 1 AND RAID 5


There are various levels of RAID .But now I explain two important Level RAID 1 and RAID 5

RAID 1:

This level provides data mirroring, which means single hard disk partition is created by two hard disk partition. Second hard disk partition will maintain the copy to the first hard disk partition. The two hard disk partition has the same Information. If one disk partition is fail then other disk partition data will be replace it and there will be no loss of dat.

RAID 5:

this level offers data stripping at the byte level and stripe error correct information. RAID 5 is striped and some data is made redundant rather than maintaining the entire copy of data. These provide outstanding performance and can tolerate errors.
