TOP RAID Data Recovery Software for FREE

RAID software tools help you to get back all the files and data you lost from RAID array disks. However, while there are many of such tools out there, not all of them are very efficient and recommendable. Hence, this article reviews the top 5 best RAID Recovery software apps to use on a PC. Interestingly, these software programs are pretty intuitive and can be run on any Windows OS computer.

Hardware RAID

Hardware RAID, as the name implies, requires the use of physical systems – controllers or RAID cards – to manage the RAID storage configuration independently from the operating system. RAID controllers process and run independently; they don’t take processing power away from the connected disks; hence, you’d get faster read and write data speeds from your RAID array.

You can easily remove and replace a failed disk from the array, but of course, purchasing additional hardware – the controller(s) or RAID cards – makes hardware RAID more expensive to set up. Furthermore, if the controller fails, you must find the same exact controller or a compatible one to replace the failed controller and get the RAID system working perfectly again.

What Are the Benefits of Using RAID?

RAID offers a bunch of benefits you may find difficult to overlook. The main benefits include redundancy and faster speeds. Other noteworthy benefits include higher fault tolerance, improved parity check, and higher data security.

1. Improved performance | Faster Speeds

One of the great benefits of RAID is providing faster speeds for data storage. For example, if you want to save a 2,000 MB (2 GB) file on a storage drive with a maximum read & write speed of 200 MB/s, it’d take 20 seconds for the transfer to complete. On the flip side, if you have a RAID array of 10 x 200 MB/s hard drives, transferring the 2 GB file only lasts for 2 seconds as the 2,000 MB would be split among the ten disks – each disk saving just 200 MB of the data.

2. Data Redundancy

Redundancy means you can still access your files even after one or more disks fail in your RAID array. If you’re setting up a RAID array for redundancy, it means every data saved on the array will be mirrored to another disk in the array; this may take up much space, but it’s the preferred RAID setup for some people because it acts as a perfect way of backing up their important data.

When Is RAID Data Recovery Needed?

There are pretty many scenarios that can lead to data loss on RAID array disk; the most common scenarios are discussed below.

User Mistakes

You can call this “accidental deletion,” in the sense that this data loss scenario occurs when the RAID storage user mistakenly or accidentally deletes one or more important files or folders and need to recover them back.

Data Corruption or Malware Attack

RAID technology does not actually offer protection against data corruption, which may occur due to third-party software bugs, disk errors, or malware attacks. When a saved file is corrupted, you need to retrieve a previously uncorrupted version of the file to regain access to the content.

Physical damage

For pretty many reasons, one or more of the disks in a RAID array may get physically damaged, which may affect the accessibility of the drive by the user or system’s OS. Some RAID recovery solutions can access inaccessible drives and get back your important data.

Overwriting Existing Data

Maybe you saved some new files, and it appears like the new file had overwritten some important files on your RAID disks; this happens rarely, but many have been faced with such data loss situations.

Formatting Gone Wrong

When you attempt to format a disk – maybe to another file system format – and along the line, the formatting process gets interrupted, you may end up losing some important files saved on the disk.

Steps to Recover Data from RAID Hard Drives

Need to repair software or hardware RAID? Hereunder are steps to how you can recover files from your RAID drives using a professional RAID Recovery software.

1. Connect One of The RAID Drives To Your Computer

To start with, you need to remove the RAID drive(s) where the file(s) you want to recover is saved, then connect the drive(s) to your computer where the RAID recovery software – DiskInternals RAID Recovery – is installed.

2. Scan The Drive

Launch the recovery app and select the RAID array for your inserted drive, then proceed with choosing a Scan Mode.

There are two modes available: Fast Scan and Full Recovery mode. Whichever you choose, DiskInternals RAID Recovery will check the status of your RAID array, controller, file system, and disks, then retrieve the deleted files.

3. Recover Lost Files From The RAID Drives

The retrieved files will be available as “Read-Only.” You can preview them to confirm that they are the files you want to recover. When you have confirmed, then you will need to upgrade to DiskInternals RAID Recovery Pro to complete the recovery.

Repeats the steps to recover files from all of your connected RAID array disks. If you can’t recover your files using the DiskInternals app, you can request for Guided Repair Service to have a DiskInternals expert attempt the recovery in a more professional and manual way.

The ZAR software is replaced by Klennet Recovery, another impressive tool for all kinds of data recovery needs.

How we tested the best data recovery software

1. 1. Performance. A common issue with many of these recovery programs' rescue functions is that they only support a few different file formats. When a recovery application supports the restoration of a wide range of file formats, you may safely recover deleted pictures, videos, audio files, and other file types. Another unhappy discovery is that the bulk of your products do not support file recovery from external storage devices like external HDDs or USB flash drives. This is really unpleasant because the bulk of data loss today happens on external or portable storage devices.

1. 2. Speed. Nobody has enough time in this day and age. The scanning and recovery processes cannot be expected to take an entire day to complete before users can access something important. Most efficient data recovery software packages include options for fast scanning. Some even provide customized scanning while concentrating on the recovery of a specific file.

1. 3. Preview. The ability to preview already-identified files is a crucial feature. The recovered files must also be in the same quality as they were originally.

1. 4. User-Friendly. Having the finest data recovery program in the world is useless if only the creator can use it. Any software must have a straightforward user interface and be simple to use. Many recovery solutions have bright icons and ostensibly advanced functions that are actually fairly pointless. Most of the time, all the end user really needs is a clearly defined interface that works.
