The issue with hard drives in RAID arrays is the read timeout. A drive that is optimised for non-RAID will do more retries when reading in the hope of getting good data while the RAID optimised drives will return an error quickly and let the other drives have a go. In spite of thus desktop drives work well in RAID arrays apart from poor performance when things go wrong.
I am not aware of SSD having such timeout issues. Can you cite a reference? In terms of what disks do there's no difference between a mirror and RAID5+.
