What Is RAID?
RAID is a type of file storage technology – previously used by large corporations only, but now used by even home users – where data is saved across multiple disks in an “Array.” The term RAID is short for Redundant Array of Inexpensive Disks, and it is a data storage virtualization technology.
There are pretty many types of RAID storage called “Arrays.” You need at least two different disks to create a RAID array. With RAID storage technology, PC users and companies can combine as many disks as possible to create a large logical storage unit where data is saved and backed up immediately.
Also, RAID storage has a lot of benefits to offer, but the benefits are dependent on the type of RAID array you create. The main benefits of RAID storage are data redundancy and fault tolerance, in the sense that – depending on the RAID array you created – you can still access your file(s) when one or more disks fail in the array.
Initially, RAID storage was used by server administrators and large corporations to create large logical storage at minimal costs, but the storage technology has grown to become common among many tech-savvy individuals for creating personal DIY cloud storage or home media centers. There are two major types of RAIDs, hardware and software RAIDs
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.
Software RAID
Software RAID does not require any additional hardware to set up – you only need the disks you’d be using in the array. However, software RAIDs run in your operating system, meaning more processing power is being put on your OS, which can cause slightly lower read and write data speeds.
However, the cost of setting up a software RAID is cheaper, and you can easily reconfigure the arrays without getting a new RAID controller. The disadvantage of software RAIDs is that they tend to be slower compared with hardware RAIDs. Also, software RAID is OS-specific; you can’t use it on multi-OS partitions and replacing a failed disk is a bit more challenging.
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.
What Is RAID Recovery?
RAID recovery refers to the process of retrieving the files and data lost from a storage disk used in a RAID array. Yes, as secure and reliable as the RAID storage technology may appear, it is not formidable against data loss. Your RAID array disks may fail or get corrupted; thus, you’d need to get back your important files using a RAID recovery software app.
Different types of RAID arrays have different tolerance levels; RAID 0 arrays do not offer data redundancy, so if you lose your files from such arrays, you won’t have any other way to access the files asides from launching a RAID recovery practice. Regardless of the RAID array type you’ve got, you can always retrieve your lost files using a professional RAID Recovery software.
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 recover data from RAID drive? 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

How we tested the best data recovery software
- 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.
- 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.
- 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.
- 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.
Common Causes of RAID Failure
Quite a lot of actions can cause RAID disk failure, but the most common causes are listed below:
- Multiple disk failures due to bad sectors or malware
- Power surges
- Incorrect configurations
- Partitions losses
- Wrong replacement drives
- RAID controller problems
- Power surges.

Bootable RAID recovery software - how it works?
Bootable RAID recovery software is a specialized tool designed to recover data from a RAID array without the need for the host operating system to be running. It is particularly useful in situations where the operating system is unbootable, or when you need to recover data from a failed RAID array without risking further data loss by operating within the potentially compromised system environment.
Step-by-Step Functionality:
Creating a Bootable Environment:
- The software is typically provided as an ISO file that you can burn to a CD, DVD, or USB flash drive.
- When you boot from this media, the software initializes its own operating environment independently of your OS, often based on a lightweight version of Linux or another minimal OS.
Accessing the RAID Array:
- Once booted, the software can directly access the RAID controllers and the disks in the array, bypassing any damaged or problematic OS-related issues.
- The software usually has built-in drivers and tools to interact with various RAID controllers and configurations, making it versatile across different hardware setups.
Scanning and Analysis:
- The software scans the RAID array to identify its configuration and to locate existing, deleted, or damaged data structures.
- It can often reconstruct the RAID parameters if the RAID metadata is corrupted or lost.
Data Recovery:
- After identifying the files and structures, the software allows you to recover and copy them to another storage location, such as an external hard drive.
- The recovery process aims to extract data without altering the original RAID setup, preserving as much data integrity as possible.
Usability and Precautions:
- Bootable RAID recovery software typically features a user-friendly interface that guides you through the recovery process.
- It's crucial to recover data to a different storage device to avoid overwriting data on the original array.
