RAID originally means redundant array of inexpensive disks, and now it commonly stands for redundant array of independent disks. RAID refers to a data storage virtualization technology of combining a lot of inexpensive disks into a single logical unit to improve the hard drive performance and achieve data redundancy. By using this technology, the data will be divided into many sections and are stored on multiple hard disks. In RAID, multiple hard drives can transfer data at the same time. Moreover, RAID has great tolerance for errors, which makes it safe to your data security.
Due to differences in hard drive capacity, data transmission speed and data reliability, RAID can be divided into many levels, including RAID0, RAID1, RAID2, RAID3, RAID4, RAID5, RAID6, RAID7, RAID10 (1+0) and RAID53, thereinto, RAID 0, RAID1 and RAID5 are used commonly.
RAID is widely used in hard drives for data protection and high data transmission speed. Unfortunately, as time goes on, a large amount of data is stored in the RAID partitions, which may cause low disk space on the RAID array. Let’s see an example:
“I created a RAID 1 array, but recently I found my system partition is running out of space. My computer ran very slowly. I tried to use Disk Management to extend my system partition, but it didn’t work. Any suggestion to solve this problem? ”
From this example, you know low disk space issue on RAID partition is also very common. When experiencing this case, you need to increase RAID partition size to improve your computer performance.
Take system partition as an example to extend partition.
Windows has a built-in partition and disk management tool which is called Disk Management. It can be used to extend and shrink RAID partition. Please open this tool and right click your system partition to select “Extend Volume” feature. However, if there is no unallocated space on the adjacent right side of the target RAID partition, “Extend Volume” grayed out.
Maybe you consider shrinking a partition to get unallocated space, however, the unallocated space is not adjacent to the system partition in Disk Management.
Consequently, it is useless to resize RAID partition with Disk Management. Fortunately, in order to achieve this aim, a professional partition management software – MiniTool Partition Wizard is highly recommended to you.
You can use this excellent partition software to move/resize partition, wipe/delete/extend/shrink/split partition, copy disk/partition and so on. As a professional and reliable RAID partition manager, MiniTool Partition Wizard is really powerful in resizing RAID partition size.
Here is the guide about how to resize partition size on RAID array:
Step 1: Right click a partition which is adjacent to your system partition and select “Move/Resize”.
Step 2: Move the slider to the right to leave some unallocated space after your system partition.
Step 3: Then right click system partition to click “Move/Resize”.
Step 4: Move the slider toward the right side, and then you can increase the RAID partition size.
Step 5: At last, click “Apply” to perform all operations.
In addition, there is another way to extend RAID partition. Just right click the target RAID partition, and select “Extend” to increase partition size. During the process, you can take some unallocated space from another big partition. Also you can ensure how much free space you want to take by moving the slider.
In conclusion, MiniTool Partition Wizard is quite useful and powerful to resize RAID partition. When there is a need, try this free RAID partition manager at once. Download it now.
