Raid Data Recovery

Raid data recovery is somehow different from all other types of data recovery. Most experts advise not to try to recover the data yourself before sending in the hard drives to a data recovery company. This is because most companies found that most of the times simple users try to recover the files all by themselves, they fail and not only. Their actions will make the recovery process even harder and if the lost information is important, someone will be in big trouble. If it's about raid data recovery better handle it quick to the professionals without touching anything.

For example, previous happenings have showed that, when a RAID failure occurs and results in the loss of important data, somebody's job is on the line! If the data is not recovered, then things get quite complicated, for the employee, as well as for the employer.

RAID 0 is simply striping the data across multiple disks. It's like dividing the data into smaller pieces of fixed size, called the "stripe width," and writing the stripes across the disks. If the file to be written was 5KB in size, with a stripe width of 1KB and there are 4 disks to a RAID set, the first stripe would be written on the first disk, the second on the second disk, and so on up the fourth stripe, the fifth stripe is written to the first disk. This is a fast way of writing large files but if one disk fails, the whole set fails.

RAID 1 is also called mirroring. That's because the same data is written on two disks at the same time. In other words, one disk being the mirror of another. The reads are done on both drives as well. If one disk fails, there is still another disk which keeps the data safe and read-write operations continue. This is an effective solution at the cost of having two disks doing the job of one.

RAID 0 + 1, is a combination of RAID 0 and RAID 1. The data is striped across disks first, and then mirrored across the same number of disks. If you have four disks, the data is striped across the first two, and then the pair is mirrored across the remaining two disks. This is a robust solution but very expensive.

Even if raid data recovery sometimes can become expensive, most companies will not charge you for an evaluation of a complex raid system. If you need the help of the experts, get it, it's the best way. After getting all your data back, make sure to always backup your information from now on.
