Difference Between RAID Recovery and Hard Drive Recovery

Data recovery has always been a hot topic. To successfully recover data from the device, you should understand how it stores data. You can learn about the difference between RAID recovery and hard drive recovery from this MiniTool article.

Data loss occurs unexpectedly due to various reasons. Even if you use multiple hard disks or RAID arrays to store data, your data is easily lost. Before we dive into the difference between RAID recovery and hard disk recovery , we will briefly introduce how RAID arrays and hard disks store data. A better understanding of the data storage mechanism helps perform secure data recovery on different devices.

Data storage on RAID arrays and hard disks

How to save data in RAID arrays

RAID arrays (redundant independent disk arrays) are data storage architectures that combine multiple disks into one logical unit. It saves redundant data to ensure data security. Even if one disk in the array is corrupted or corrupted, you can still read the data because the same data is also stored on other hard disks.

Here are several ways to save data in RAID arrays:

• Striping : The data is divided into block sizes and stored on other disks, allowing all disks to read data.
• Mirroring : Data on one disk is copied to other disks. This requires multiple disks.
• Parity : This method requires at least three disks. The data is divided into chunk sizes and saved on two of the three disks. The third disk is used to store data from the first two disks.

How to save data from hard disk

Compared to RAID arrays, hard disks are relatively simple to save data. A normal hard disk stores its data on a disk coated with thin magnetic material. Because the data storage method is simple, the hard disk does not have any measures to prevent data loss.

RAID data recovery and HDD data recovery

You should understand the difference between RAID and hard drive data storage. Due to these differences, data recovery on RAID arrays and hard disks is also different.

RAID Recovery

RAID recovery refers to recovering data from a RAID storage architecture. As mentioned above, a RAID array contains multiple disks. It is important to determine which disk is corrupt or not working properly. You can complete RAID recovery by rebuilding the RAID array or recovering data from the target disk.

Hard disk recovery

Hard disk recovery is to extract data from hard disks that have lost data due to accidental deletion, unexpected formatting, device crashes, etc. New data saved on the hard drive may overwrite the lost data, resulting in data recovery being unavailable. Hard disk recovery is usually done with the help of the data recovery service as long as the lost data is not overwritten.

How to recover data on RAID array/hard disk

MiniTool Power Data Recovery is a powerful tool for RAID arrays and hard drives. In addition to the above two cases, you can also run this software to retrieve files from SD card, USB drive, memory stick, etc. With professional technical support and a secure data recovery environment, this tool may be ideal for you.

You can get MiniTool Power Data Recovery free version, perform deep scans and recover 1GB of files for free.
