RAID is a hard disk group combining several independent physical hard disks in different ways so as to provide higher storage performance and data backup technology than single hard disk. Data backup is to recover damaged or lost data in the event of data loss or data damage, guaranteeing data security. In user's opinion, combined disks are like a hard disk on which user could format, partition and much more. RAID could give full play the advantage of multi-disks, far exceeding the speed and throughput of a single hard disk. Apart from the enhancement on performance, RAID still offers excellent fault-tolerant capacity. On the other hand, however, once error, data loss in particular, emerges on RAID, the expense can be costly. In this sense, I would like to recommend user a powerful data recovery named MiniTool Power Data Recovery.

Development of Raid technology
RAID technology falls into several different classes, providing distinct speed, security performance and cost performance. Choosing suitable class in accordance with actual situation could satisfy user's needs over storage system availability, performance and volume. Usual RAID classes include NRaid, JBOD, Raid0, Raid1, Raid0+1, Raid3, Raid5, etc. The most densely-utilized RAID5 and RAID (0+1) feature in speed and security performance, which allowed early RAID technology to be applied in SCSI interface hard disk system on advanced server. Along with the development of computer technology, the leapfrog improvement of CPU on PC makes the application of RAID on mid/low-standard PCs possible.
Functions of Raid:
1. Expand storage capacity.
2. Reduce the cost of unit capacity.
3. Elevate access speed.
4. Higher reliability.
5. Fault-tolerant.

Recover data from lost partition with MiniTool Power Data Recovery
Here is a demo on performing lost partition recovery with MiniTool Power Data Recovery software:
First, download MiniTool Power Data Recovery at http://www.powerdatarecovery.com/ and then install it to computer. Launch MiniTool Power Data Recovery to meet the interface below:



Check "I am a home user, please launch MiniTool Power Data Recovery Free Edition" and then click "Launch Power Data Recovery Free Edition" to enter main interface.



Select "Lost Partition Recovery" to activate next interface.



Select the hard disk suffering partition loss, then click "Recover" to scan entire disk.



This interface shows the possible partition status on this disk, select the highest suggested partition and click "Show Files".



Check all needed files and click "Save Files" to store them onto desired location. Thus, the RAID recovery has been successfully performed with the excellent data recovery software.
