Are Windows 'Storage Spaces' roughly equivalent to BIOS pre-boot type RAID systems?

I use a 2TB C drive as one unit (plus standard hidden Microsoft OS volumes) and a 2TB 2nd drive unit I have split into a NTFS drive of most space usage, and a Dev Drive smaller for my repos and such for application development. I'm interested in using a SATA in-bay SSD to either RAID or Storage Space my main C drive, at this point. The D and R drives (for the second physical m.2 drive disk hardware) I'm planning to go easy on the budget and thus await until later to maybe try to RAID or Storage Space those, instead using them as "my data" and "my developer app solutions/projects" volumes. These I backup twice to store in one obvious place in my apartment and one obscure out of reach place, for data contingency preparedness of very unlikely theft. That's after realizing over a year ago that services such as Carbonite and CrashPlan miscue with a false sense of data security. Manual backups using Second Copy 9 is my technique. But conveniently, my C drive is nearly empty of personally created or downloaded unique data, so is ripe for RAID or Storage Space, with that even fairly failure-benign on data loss, but not at all failure-benign on workload and time spent to reinstall so much application software and reconfigure settings and such. The real information I could use is opinions or knowledge on how RAID and Storage Spaces compare, and any gotcha issues with the Windows 11 Storage settings, with Settings tweaks notorious for too easily and readily prone to me (the user) accidentally selecting an erroneous option on the Settings app and making a mess. Thanks for any information! — Patrick
