RAID 5 volume can only be created in dynamic disk and its creating conditions differ from partition. Partition can be created in basic disk but RAID 5 volume needs at least three dynamic disks. RAID 5 volume always deals with a large amount of data so it needs large capacity. RAID 5 volume saves data and corresponding parity information to each disk separately. That means there are N-1 disks for saving data and one disk for saving parity information. Therefore, actual free space in RAID 5 is smaller than the physical disk space.
Expand RAID 5
As we all know that RAID 5 is dynamic volume with large capacity and there is always one dynamic disk being unable to save data, so when we create RAID 5 volume, we need to set the capacity larger. Sometimes we have to expand RAID 5 partition for there is not enough space. Most users will firstly try to use Windows built-in disk management tool. Though it has simple operation, its disadvantage is that it cannot guarantee data security while expanding. What we need is professional dynamic disk manager.
