RAID ( Redundant Array of Inexpensive Disks) technology is considered to be the most reliable storage medium. It is a configuration in which various low-cost disks are attached together into arrays for redundancy. RAID is used to divide and replicate data among multiple hard-disk drives. But, despite being a reliable storage medium, RAID is vulnerable to failure. You may observe inaccessibility of your data after RAID failure. To overcome such situations, you can restore your data by using a complete and recent data backup. If in case, the backup is corrupt, absent or incomplete, then you will need to use professional Hard Drive Recovery Services.
RAID is known for it's high storage capacity and superior performance. RAID increases the fault tolerance of the system, as the system keeps on working even if it encounters with any hardware or software issues. Depending on the RAID configuration, there may be an increase in simultaneous reading and writing of drives. Besides this, RAID enables you to store data on multiple hard disks present in the array. So, failure to one hard drive in the array may not result in data loss.
But, even RAID also faces some problems that lead to data loss. When the RAID fails, you may lose all your critical data. Following are the main causes for RAID failure:
- RAID controllers fail to recognize the disks present in the array.
- RAID reconfiguration.
- Parity loss
- Missing RAID partition.
- Loss of RAID volume due to multiple hard drive failure.
- Volume reconstruction issue.
- RAID redundancy loss.
Resolution:
RAID failure can result in severe data loss and it can spoil or halt the working of a business or an organization. In such situations, a reputed Data Recovery company will enable you to recover all your data from failed RAID drives. These companies offer specialized Hard Drive Recovery Services to ensure complete and systematic recovery of your data. These companies use high intense methods to extract your data from the physically damaged hard drives successfully.
