If you have dealed with big data, you may have heard of RAID (Redundant Array of Independent Disks). It is a dedicated technology aiming to improve hard drive performance and security. 

However, some people may do not know what RAID is and how RAID manages to help. Except that, when users bump into a difficulty where they lost data from RAID hard disk, how to carry out RAID disk recovery becomes an essential problem.

In this article, you can get an answer to all your problems on the RAID technique and free method to recover data from RAID drives. Let's begin right now!

Overview of RAID

RAID is an acronym for Redundant Array of Independent Disks. It is a kind of technique that can organize several physically independent hard disks into one logical hard drive array in different ways.

The main goal is to improve hard drive speed and reliability. The reliability and speed level is decided by RAID levels. The following are different RAID levels:

  • RAID 0: As for RAID 0, data bytes are written on several disks. The biggest benefit is that there is no redundant data with an extremely high transfer rate. However, data reliability is not assured. One invalid hard disk may lead to the whole data loss of the RAID drive.
  • RAID 1: One disk is mirrored by the other pair. In this way, the pair becomes their backup hard drive reciprocally. RAID 1 hard drive ensures the performance and security of data. But its unit cost is the highest
  • RAID 10 (RAID 0+1):  This one requires at least 4 drives and combines RAID 0 and RAID 1, giving you increased speeds and redundancy.
  • RAID 2 & RAID 3 & RAID 4: Regarding RAID 2, RAID 3, and RAID 4 technique, the data bar will be distributed on several hard disks in blocks. All of them provide a high transfer rate for big amounts of continuous data.
  • RAID 5 & RAID 6:  RAID 5 and RAID 6 hard drive have relatively high reliability. The reason is that the odd and even hard drives adopt different algorithms.

You may wonder which RAID level suits you best. Actually, three factors will influence your decision: usability, performance, and cost. If you prefer high usability, RAID 0 is the best choice for you. But if both usability and performance are important factors, choose RAID 1. If usability, cost and performance are all necessary, then RAID 3 and RAID 5 are designed for you.

Causes for Data Loss from RAID Hard Drive

From the RAID levels mentioned above, you now know which RAID level is suitable for you.

And you should not run into a wrong idea: Hard drive problems and data loss will not happen on the RAID hard disks because its performance and speed have been promoted a lot. In fact, RAID disk failure happens occasionally, and the most common causes are listed below:

  • 🔧 RAID controller failure: It can cause booting problems which may result in data loss.
  • 💻 RAID partitions corrupted: You could lose part of data on the partitions or lose all data on the RAID hard drive.
  • 🚨 RAID volume built incorrectly: You may have data accessing problems or be trapped by system breakdown.
  • 🔌 Out-dated server crash: RAID data loss may occur.

Many reasons will lead to RAID hard disk data loss, thus a backup is indispensable.

If your data loss did happen and you didn't backup the data before, you need to carry out an immediate RAID disk recovery. Please go on to find out what you want.
