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

However, users still ask 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 get data from RAID hard drive becomes an essential problem.

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

All You Need to Know about 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 hard drives:

• RAID 0: As for the RAID 0 technique, 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. It is because that the odd and even hard drives adopt different algorithms.

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

Possible Causes for Data Loss from RAID Hard Drive

From the above section, you must 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:

• The RAID controller failure can cause booting problems which may result in data loss.
• The RAID partitions are corrupted, you could lose some data on the partitions or lose all data on the RAID hard drive.
• If the RAID volume is not built correctly, you may have data accessing problems or be trapped by system breakdown.
• An out-dated server crash can also be a major cause of RAID data loss

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

If your data loss did happen, you need an immediate RAID recovery. Please go on to find out what you want.
