How to simply increase or expand the size of an Adaptec RAID 5 array hosting SSD hardware in Windows 10.

After much research on the web, I could find no easy way to accomplish this. Most websites want you to buy some third party software after you swap out the drives, but only after you backup the image and create a new array. Long way to go!

Here is what I did for a simple solution: One at a time, I added in a larger Global Hot Spare (250GB) and pulled each smaller Raid 5 disk (120GB) in order. The smaller disks were individually pulled and replaced after a series of shut-downs (three for the 3 disks). After each new larger disk was rebuilt, I had to unmark that disk as the current Hot Spare and then add in the next Hot Spare and mark it accordingly using the Adaptec GUI on boot (Ctrl A).

After all the new and larger disks were all rotated in, I then used the Adaptec MaxView Storage Manager to expand the array to its maximum size (no third party software needed such as Partition Magic, etc.).

The larger array works great now at double the size!
