Spindles had higher rates of failure....so RAID was smart for ultra important computers that needed uptime (like servers)
SSDs are reliable, and should outlive the life of the computer. MUCH less of a need for RAID.
To me, the reasons to have a RAID controller are things that REAL RAID controllers have..dedicated processor, battery backed cache, features like online expansion, etc. RAID controllers that do this typically have a comma in their price tag, and aren't available for residential/desktop class computers. Yeah you see motherboards or computers that support RAID...but those are what I call "fake RAID"...it's a cheesy support that is still CPU robbing and limited in features.
I know a lot of people shrug away from OS based RAID...but really it is decent, not much of a performance hit. For a home user I'd do OS RAID. Since the so called hardware options to do RAID really aren't much better, if better at all. Windows RAID is easy to repair if it breaks...I actually find it easier than those el crappo built in fake-raids.
But again..for a residential user, with SSDs...I'd just pass on RAID and focus on backing up data. Heck with Windows 10 installing so quickly, and installing software also goes quick on todays systems, even basic stuff like having OneDrive makes rebuilding a computer and putting your data back very quick and easy. Heck probably quicker than trying to repair a broken fake RAID setup!
