What’s SSD unallocated space?

SSD unallocated space may be formed by deleted partitions which are needless. Luckily, it can be reused to store new information as long as you merge it into existing partitions or directly create partitions on it. To do so, we recommend youAOMEI Partition Assistant, a free and professional partition software.

How to use SSD unallocated space?

When you want to make the unallocated space useful, you can reallocated it so as to make it be volume again. As a volume can be written or read, the unallocated space can’t be used which is a big waste. But how to do this? You can add a partition on the unallocated space of what size you prefer or just merge it into other partitions. Though, Windows itself has the same feature of doing the job, but the restrictions of it are terrible - it can only extend an unallocated space into an adjacent partition and the unallocated space must behind the target partition. Therefore, a free and convenient partition software is much better, such as AOMEI Partition Assistant.
