Here you will find out:

• should you defrag a RAID
• what you need to know before defragmenting RAID
• when DiskInternals can help you

Are you ready? Let's read!

What is defragmentation?

RAID defragmentation is the process of collecting fragmented disk components in a designated position in order to optimize the performance of the entire array as a whole.

Defragmentation has several key advantages:

All this is due to the defragmentation mechanism itself - it removes the “gaps” that result from using (deleting information, moving it, etc.) free disk space. As a result, the search for the requested information is much faster.

Recent versions of Windows already have this feature in automatic mode. However, double-checking is still worth it.

Defrag RAID or not?

If your RAID includes HDDs, defragmentation is crucial for optimizing the array and enhancing its performance. However, defragmenting SSDs is generally disadvantageous.

Defragmenting an SSD might initially improve performance, but it can lead to quicker wear and potential damage to the array. SSDs degrade faster when fragmented. The TRIM command was designed for SSDs to help clear unused flash memory blocks efficiently.

The only valid reason to defragment an SSD is if it's old and soon to be replaced; this might temporarily improve its speed.
Regarding flash drives or any removable storage, defragmentation is not recommended. Such actions can lead to rapid deterioration due to their limited write/read cycles. It's unlikely you'd want to intentionally damage these drives.

Save your recoverable data before defragmentation

DiskInternals RAID Recovery is exactly the application that you need before defragmenting the array.

The program will not only correctly restore hardware or software RAID, but will also help to create a disk image for an emergency. The application works with all levels of raids while automatically determining all the required parameters - this, in turn, will greatly facilitate your life. In addition, you can immediately use the services of the Recovery Wizard, and then you just need to follow the instructions of this assistant without making any efforts. If you are restoring files, you should definitely use the Preview files before exporting.

This feature is free and required, as DiskInternals values its reputation and saves you from unnecessary purchases. If you liked the search and recovery results, then it's time to purchase a license and complete the export of this data to another data storage device.

Also, put into practice the instructions for DiskInternals RAID Recovery:

Download and install the application on your PC, then run it.

Open the Recovery Wizard, if necessary.

Select the array to scan from the list provided.

Click on the desired scan mode: Uneraser(preferable), Reader, or Recovery.

Wait until the results appear on the monitor screen, and then view them for free (right-click on the Preview function).

Buy a license and use the Export Wizard to complete this last step of saving data.

Be careful and patient, then you will succeed. Good luck!
