RAID 5 is a common RAID setup used frequently in small businesses and other organizations.
Like other storage devices, RAID 5 could be corrupted due to different reasons.
Once a RAID 5 crashes, data saved there will be put in danger.
Now, I will show you how to perform RAID 5 data recovery easily and quickly.
Then, tips on how to rebuild a RAID 5 will be given to you.
Tip: How to recover data from a virtual disk?
The balance between performance, capacity, reliability, and availability, is different in different RAID levels.
Once you find your RAID is corrupted, you should start to recover data from RAID without any delay.
In both situations, you better follow the steps given below to recover data from degraded RAID without hesitation.
Can I recover a RAID 5 array if two drives have failed?
I have a Dell 2600 with 6 drives configured in a RAID 5 on a PERC 4 controller.
Im not sure if the fact I had six drives in the array might save my skin.
I bought 2 new drives and plugged them in but no rebuild happened as I expected.
Can anyone shed some light?

How many disks can you lose in RAID 5?
That is to say, the RAID 5 can survive if there is only one disk damaged.
It can help yourecover data from both crashed diskanddisks with problematic partitions.
Step three: launch theRAID recovery softwareand pick the proper function from the left pane.
Step six: clickSaveto choose a storage path in the pop-up window.
Then, clickOKto confirm and wait for the recovery process to complete.

You will see the following prompt window when clicking onSave.

When the data recovery is finished, you should give a shot to rebuild the RAID 5.
Before the rebuilding process, you may ask how much time is needed to complete the process.
Actually, there is no definitive answer.
It is very important for storage administrators, especially enterprise administrators.
The failure of both another drive and thecontrolleris going to result in a failed rebuild process.
Heres how to recover data lost after CHKDSK:
Does your files get lost after CHKDSK?
Here are ways to help your recover CHKDSK deleted files in few steps.
That explains why RAID 5 can continue to work after a single drive failure.
Thus, RAID 5 is regarded as one of the most reliable RAID schemes.
It greatly improves the bottleneck problem triggered by parity data storage.
Though RAID 5 can be achieved by virtue of software, it is not advisable.
How Does RAID 5 Work
What is striping?
It actually refers to storing consecutive segments of data to different disks.
This is a good way to get better throughput and performance.
Disk striping, together with parity, offers RAID 5 with redundancy and reliability.
The benefits of RAID 5 are mainly come from disk striping and parity.
In RAID 5, it is parity, not the popular mirroring, that provides data redundancy.
Whats the difference between RAID 5 and mirroring?
In this way, even a single drive is failed, RAID data are not in danger.
RAID 5 is a good choice for file and utility servers which contain limited data drives.
It is also important to individual users, enterprises and many organizations.
