In general, a RAID-enabled system uses two or more hard disks to improve the performance or provide some level of fault tolerance for a machine. The purpose of a RAID system is to allow the server to survive the failure of a single system disk. Back when hard drives were less spacious and more pricey, RAID was formed to join multiple, less-expensive drives into a single, higher-capacity and faster volume. While RAID arrays are a commonly secure and dependable way to manage and access data, unfortunately even the most secure RAID configurations can fail, causing you to lose valuable files and information. This problem can be especially harmful if your data hasn’t been correctly backed up.
Considerations while choosing RAID levels
Points that you need to take into consideration, while choosing a RAID level:
- Performance. Make sure you choose a RAID level that matches the workload.
- Capacity needs. If capacity is your primary driver that will affect your choice of RAID.
- Availability needs. You need to pick a RAID level that matches the system’s availability needs demanded by your organization.
- Price. Choosing the right RAID level can play a big part in achieving the necessary balance between cost and performance is your job.

What to do in case of RAID Array Failure
The first thing you should do is turn off the array immediately. Do not ever try any physical repair of the system yourself. Contact a data recovery specialist who has the tools and facilities to accurately repair the system in order to recover your files.
