Answer to: How to partition and organize built-in SSD and HDDFor Windows users, you could use Disk Management to partitioning or manage the disks. you can merge, format, delete, shrink, extend partitions etc. However, there are some limitations about Disk Management, it isn't allow to move partition, and cannot merge partition with unallocated space which is not adjacent to the partition. Fortunately, there is a better way to solve this problem. Taking advantage of the Partition Assistant to partition and manage your disks, Partition Assistant is more flexible to use, it support more functions than Disk Management, like increase C drive space, migrate OS to SSD, allocate free space etc. Moreover, you can backup data regularly with AOMEI Backupper.
