Windows PC with Intel Chipset and Intel RAID-1. Currently the RAID 1 runs on two 1TB HDDs just with drive C.
I want to change this to a RAID-1 with two 512GB SSDs for drive C and RAID-1 on two HDDs for drive D.
If the size of the new disks would be the same or bigger I would just change one disk and let the RAID rebuild to the new disk and then repeat the process later with the 2nd new disk. But this obviously won't work with new disks which are smaller.
My idea is to reduce the size of the current RAID to 500GB and then use the above process. But I don't see a way to decrease the size of the RAID.
Does anybody know how to decrease the size of an existing RAID-1? In Windows the RAID is managed by Intel Rapid Storage Technology software which has an option to increase size but no option do decrease size.
