Here, what you will get to know is the top 5 RAID data recovery software, what RAID is, and also the principle of RAID recovery.
RAID hard drives are a specific component in a computer's data storage. They comprise of a few parallel disks covered in a case, actuator, actuator axis, actuator arm, platter, spindle, head, and the power and IDE connectors. It is designed to optimize the performance of data storage. Nevertheless, it is still likely to lose your important data from RAID hard drive. Read on and get the best RAID hard drive recovery software.
Part 1: Top 5 RAID Recovery Software
Data recovery from RAID drives can be easy or painful depending on the level of RAID and the nature of the RAID, a hardware RAID or a software Raid. Software RAIDs could turn out to be easy to recover in the manner that the data is stored in physically separate disks. It is not the case always. Software RAIDs could be as hard as hardware RAIDs when coming to recovering data upon a failed disk.
There have been problems and solutions. It gets even complicated when you want to pull out some data manually from a malfunctioned hard drive. If a hard drive is not RAID configured, you don't need the complicated methods to recover files from hard drive. To make it easier there are software applications which make RAID hard drive data recovery easy.

Part 2: What Is RAID?
On the behalf of Redundant Array of Independent Disks, RAID is a technology for better performance and reliability of data storage by incorporating multiple hard drives to work in parallel. According to different needs, the RAID level can range among RAID 0, RAID 1, RAID 5, RAID 10 and more.
A normal hard drive and RAID hard drive differ in the way of their function. Primary purpose of a RAID is to have data redundancy and to have better performance. The higher the redundancy, the higher the performance. RAID stands for Redundant Array of Independent Disks, originally known as inexpensive disks.
The functionality is achieved by the technology of combining multiple disk drives into a single logical component. The need for data redundancy and performance differ from instance to instance. So there are certain levels as to how the data redundancy and the performance would be affected. There are numbers given to the RAID mechanism to better serve the purpose. RAID 0 is the least tolerant and redundant whereas RAID 6 has two levels of error recovery.
Depending on the number for the RAID, the difficulty or easiness of the data recovery procedure will be varied. If one disk fails in a RAID 0 drives, then all the disks fail and there is no possible data recovery. It is basically a mechanism to use more than one location for data storage through parity.
The RAID mechanism could be viewed in two divisions based on the nature of the RAID in addition to the RAID numbers. There are both Hardware RAIDs and Software RAIDs.
Part 3: What Is RAID Recovery?
Normally, data recovery software is intended to recover data from a file system on various storage devices, including hard drives and removable storage media. And after a data recovery, what you can get is files and folders. However, for RAID data recovery, it is aimed to recbuild the RAID hard drive so that you can recover data from a RAID configuration, including its architecture parameters. What's essential for the RAID recovery process is to identify the RAID array.
Hardware RAID
Hardware RAID means a hardware based mechanism. The hardware is designed and incorporated to accommodate the RAID mechanism. It could either be performed through a RAID card or be built in the motherboard itself. In this type of technology, separate disks are used but the system counts them all as the same disk. The resultant capacity of the RAID drive will depend on the number of disks used and the level of RAID. Usually the higher the RAID number, the lower the resultant capacity of the disk because much space is used for parity and making data recovery much easier than the previous level. For example, if the same number of disks with the same capacity are used RAID 0, the resultant capacity will be higher than when they would be used in a RAID 6 drive.
Software RAID
Software RAID, as the name mentions, is brought about by software and there is no need for the hardware to be originally configured to be a RAID drive. In a computer system there are tools like the Device Manager to better manage every component of the hardware. The software and programming are so advanced now that we can actually manipulate the function of the hardware by advanced software. A software RAID is achieved by allocating spaces in different drives to form a virtual RAID drive. The computer will then recognize all combined spaces as one single disk or drive. In the operations of the computer, all combined components of a software RAID will be one.
Conclusion
Now you have known the basics about RAID data recovery. You can select the top 5 RAID hard drive recovery software mentioned above to start RAID recovery. If you want to recover files from hard drive, try Recoverit Data Recovery. It is a powerful hard drive data recovery tool for everyone to retrieve lost, formatted, or deleted data from any storage devices, including internal or external hard disks.
Recoverit - The Best Hard Drive Recovery Software
What's Wrong with Drive
Summary :
The RAID recovery work may be easy for some people, but it is actually difficult for most ordinary users. Here, I will make it easy for you by introducing the professional data recovery software - MiniTool Power Data Recovery.
Quick Navigation :
If you are using RAID to save data, you should be very careful as data loss can happen even on fault-tolerance combinations. Therefore, RAID recovery is the essential skill for you to do the rescue. Now, I will introduce the professional data recovery software to help you.
RAID recovery refers to the process of data recovery from a RAID array which encounters a problem for whatever reasons (maybe it happens due to uses' improper/wrong actions, a controller problem, the virus attack or something else).
The RAID recovery mainly consists of two aspects:
Here, I will mainly focus on the first aspect.
Let's start with a specific case in which RAID data recovery is needed.
I'm in a bit of a tough spot. I have 3 drives that were configured in a RAID 5 array that I need to get some data off of them. I don't have the original server equipment available or controller card that was attached to them. The array is complete; none of the disks are in a failed state. They were just removed from the previous server.
Maybe you're familiar with this kind of case, maybe you're troubled by such problem right now; either way, it indicates that RAID recovery becomes a topic which can't be ignored.
In fact, if you search 'RAID recovery', 'RAID data recovery' or related keywords in Google, you'll get lots of results within one second.
Mac Uninstalling Software Paid and Free Mac philosophy assumes that commercial soft is better. In fact, though, you don't have to pay to remove apps on your Mac. There are both paid and free versions. Free app removers, though, don't grant you support and timely updates. Even the best Mac uninstaller you can find for free has its downsides. Uninstall apps on mac mini.
According to this, you can easily find users' urgent demands for RAID data recovery/RAID file recovery. Taking this into account, I plan to show you in detail how to recover data from RAID with the best RAID recovery software – MiniTool Power Data Recovery (please choose Mac Data Recovery instead if you need to finish RAID recovery on Mac).
After that, I will talk about the causes of RAID data loss and more information about the RAID itself including:

How to Recover Data from RAID
When you met RAID data loss in the past, you have no choice but to pay much money for the RAID recovery services (either get help from professional recovery companies or data recovery software).
Now, the good news is that you have a better choice: use MiniTool Power Data Recovery – which perfectly supports common RAID types – to complete data recovery from RAID drives. Please note that I will show you how to complete RAID file recovery on both Windows and Mac platform (you only need a different version of software).
Please note:
Though in RAID 5, the disk array can work well even when disks (over two or more) are damaged, RAID 5 data recovery from damaged or corrupt RAID arrays is still important. That is because the data saved on RAID are often too significant to lose.
Now, I am going to focus on RAID 5 recovery on different platforms.
RAID Recovery for Windows
1. For the purpose of recovering a RAID-5 volume that is damaged, users should choose 'This PC' from the main interface of MiniTool Power Data Recovery.
2. After that, select the RAID 5 volume from which you'd like to recover lost files and click on the 'Scan'.
3. Now, the found files will be displayed one by one in the interface below, in which you are supposed to select all you need to recover. If there're too many files waiting for you to choose from, you could make use of Find' or 'Filter' function to narrow the search scope.
Please note that: if the data need to be recovered are pictures, photos or *.txt files, you can select a file and click on the 'Preview' button to see the real content so as to determine whether it is the one you need or not.
4. When all needed files are selected, you should recover them by pressing the 'Save' button and setting a safe storage location. This method works for both hardware RAID data recovery and software RAID recovery.
Note: if the RAID 5 array with lost data is running on a Windows Server system, you need to buy a Business License since:

If you are running the RAID array on Mac, you need the help of another program – MiniTool Mac Data Recovery. You can try the free edition firstly and then decide to get an advanced edition or not.
But you have to notice that the free edition of Mac Data Recovery only allows you to scan lost files for free. Therefore, if you find what you need after the scan, you have to acquire a license to complete the RAID recovery on Mac.
You should do the following things to complete Mac file recovery:
In short, what you should do after you found data loss on RAID:

How Data Get Lost from RAID
As I have mentioned before, RAID offers a high performance to computer users, especially those who're handing with servers. But in the meantime, it is also likely to bring troubles to them. There's a typical point of view – when system crash, virus attack, power failure/surge or other unknown reasons lead to data loss on RAID disk, things will be more complicated than data loss on a single disk.
That is because data recovery from RAID drives seems to be more difficult for ordinary users. They don't know at all what to do or what they shouldn't do at that moment. Some of them are even like ants on a hot pan and would do whatever is said possibly to rescue their RAID.
But what I want to say here is: this is totally wrong! Any operations performed after data were lost from RAID could bring secondary damage and this may result in a devastating result – permanent loss of data. Even the best RAID recovery software or the most professional data recovery experts can do nothing once lost data are overwritten. Well, what are the exact reasons that will lead to RAID data loss? Please keep reading.
6 Causes for RAID Data Loss & 3 Suggestions
Common reasons responsible for RAID data loss:
Please take following measures immediately when failure is detected on RAID disk array:
What Is RAID Exactly
A RAID consists of several cheap disks, so it is a disk group with huge capacity.
The principle is: RAID uses the individual disk to provide data, producing an additive effect so as to enhance the comprehensive effectiveness of the entire disk system.
On RAID, same data will be saved respectively to different places of different disks in the array. In this way, the input and output operations can overlap in a balanced manner to improve disk performance. By taking advantage of parity check concept, RAID is able to read data even when a disk in the array is failed. What's more, data on the failed disk will be transferred to new hard disk after reconstruction and calculation.

As a result, the MTBF (Mean Time Between Failures) is increased due to multiple disks; at the same time, redundant data storage increases fault tolerance as well.
FYI: the full name of RAID is originally Redundant Array of Inexpensive Disks, now Redundant Array of Independent Disks.
Common RAID Types
According to different classification methods, RAID array can be divided into different types. The 2 most important classification criteria are - creating way and function. RAID is divided into following types: software RAID and hardware RAID, RAID 0, RAID 1, RAID 2, RAID 3, and so on. Different RAID levels have different pros and cons.
A brief comparison of software RAID and hardware RAID:
Common RAID levels:
RAID 0: based on Data Stripping, RAID 0 is the earliest RAID mode. It is also the simplest form of disk array which needs at least 2 disks. Though RAID 0 has a low cost, it's able to improve the overall disk performance and throughput.
Deficiency: it does not provide redundancy or ability to fix bugs.
RAID 1: it is also known as disk mirroring, which provides data redundancy. The principle is to mirror data from one disk to the other one. That is to say, when data is writing to one disk, the corresponding image file will be generated and saved on the other disk. This could ensure maximum system reliability and repairability without affecting performance.
Deficiency: only half of the disk capacity is effective, which increases cost indirectly.
RAID 0+1 (also known as RAID 10): it's the combination of RAID 0 and RAID 1. RAID 10 can be simply understood as the mirroring of RAID 0 arrays. It has the following features.
Also note that for the process to work smoothly, Canon suggests that your computer run one of the following operating systems.

Otherwise, you can damage the camera or the memory card.
RAID 5: its parity code exists on all disks in the array, so the reliability is increased. The principle is cutting data parity on each disk into pieces and saving them to all disks in the array. This eases the bottleneck problem arising from parity data storage at the price of sacrificing speed.
Deficiency: data transmission parallelism and the design of controller are hard to handle. Why People Set up RAID
3 main purposes of creating RAID array are:
Besides, when users get their hands on deploying an enterprise-class server, RAID is essential for them. Why? It is simple to explain – redundancy is very important for a server system since the drive may be failed and the server may be crashed, resulting from many unexpected issues.
In a word, RAID is necessary in some cases to help people increase disk performance in the way they want. And the creating process of disk arrays is not so complex that most of the users can actually finish by referring to an online tutorial.
