It provides you with two methods to enlarge RAID 5 volume for different situations (whether there is free space in all other virtual drives on the RAID 5 array or not). It has a great dynamic disk manager to help users to manage dynamic disk and volumes (including expanding RAID 5 volume) easily and safely. Here we recommend using AOMEI Partition Assistant Server.

But how to do it specifically? This task needs the help pf a professional dynamic disk manager because Windows built-in Disk Management or DiskPart cannot extend RAID 5 volume. So, sometimes you may need to extend RAID 5 partition. When one drive fails, the system can calculate the lost data through the parity data stored on the rest 2 drives so as to ensure the data security.īest tool to expand RAID 5 volume in Server and Windowsĭue to the mentioned advantage (data security), the RAID 5 volume is always used to deal with a large amount of data, so it needs a large capacity. When data is written to a RAID 5 drive, the system will calculate the parity and writes the parity into 3 drives. It is always considered as one of the most secure RAID figuration because it uses parity for data redundancy. And the RAID 5 volume is one advance dynamic volume type created across at least three dynamic hard disk drives. The RAID is a data storage virtualization technology that provides a way to save the same data in different places on multiple (at least two disks) physical hard disks. It is short for Redundant Array of Independent (Inexpensive) Disks. I don’t want to back up all data on the existing RAID-5 volume to another storage disk, and then break the RAID-5 array, afterwards recreate RAID-5 volume with all the four disks, and then restore the data to the new RAID-5 volume.īefore learning what is RAID 5 volume, we should first know the word “RAID”. I'm wondering how can I expand RAID 5 volume space without damaging the existing data. I've got a 3 x 2TB RAID 5 array, and the discs are of low disk space now, so I'm starting to want more space and add a new disk.
