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.
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 up 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 to use the complicated methods. To make it easier there are software applications which make raid hard drive data recovery easy.

DiskInternals raid recovery uses a fully automated system for data recovery from RAIDs. It is not mandatory to have an automatic data recovery with this raid hard drive data software; you can also do it yourself manually.
GetDataBack software come in two forms, one for FAT and one for NTFS file systems. You can purchase based on your need.
ReclaiMe Free raid recovery is not an entirely free data recovery software. This is a platform where you can actually see which files are available for recovery. You can decide whether you have the data you needed or not.
This software allows you to recover data from your storage drives with various issues to solve. Raid data recovery is one of the options. This software performed a number of other functions.
This is a collection of software initially produced by R-Tools technology. It uses some of the advanced techniques and features in data recovery today.
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.
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, 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.
