Many users reflect that they don’t know how to resize RAID 5 and they are afraid of data loss by using a third-party software to manage RAID 5. Actually, it is very easy and safe to partition RAID 5as long as you use a reputable and reliable disk manager. This article will show you how to safely partition RAID 5 without losing data with a reputable software MiniTool Partition Wizard.

What Is RAID 5

RAID 5 is a storage medium solution that has great performance, high security, and low cost. It is the compromise solution of RAID 0 and RAID 1. RAID 5 has similar data accessing speed with RAID 0. But it saves parity information at the same time so it is a little bit slower than single disk. Multiple pieces of data are corresponding to one piece of parity information, so RAID 5 has higher disk space usage rate and lower cost than RAID 1.

RAID 5 can be realized by Disk Array Controller or some professional disk management software. After converting basic disk to dynamic disk, we can partition RAID 5 with professional dynamic disk manager. RAID 5 volume guarantees data security. Compared with mirrored volume, RAID 5 has lower security but higher disk usage rate. This kind of RAID 5 made by software is called software RAID 5. And this is the simplest and most effective way.

RAID 5 partition has many advantages like excellent performance, good fault tolerance, high capacity and storage efficiency. You can try to create RAID 5 if you have three dynamic disks in your computer and your operating system supports RAID volume. To create RAID 5 you need at least three disks but 32 disks at the most. And RAID 5 volume cannot include boot partition or system partition.

Partition RAID 5 in Disk Management

Windows built-in partition tool Disk Management can help you create RAID 5 Partition if there are three dynamic disks in your computer and your operating system supports RAID volume. If you just want to create RAID 5, you just need to right-click the unallocated space and choose New Volumeto create RAID 5 volume by following the step-by-step instruction.

However, if you want to extend RAID 5 partition or shrink RAID 5 partition, you will find that these features are not available in Disk Management as shown in the following picture. You have to delete the original RAID 5 volume and then create a new one, which, of course, is very inconvenient and will cause data loss.
