I've been using RAID for well over twenty years. I use RAID 0, RAID 1 and RAID 5 depending on the use. I use RAID 0 ONLY for things like Photoshop scratch disc - because it's the fastest and, more importantly, there's never going to be anything stored permanently on a RAID 0 pair (and yeah, you can have more than two but most are just doing two). If one drive fails in a RAID 0 array you lose everything on both drives and that's not an acceptable risk for me. For all my working files and projects, I use a two drive RAID 1 - both for Photoshop and for Logic, well I did for Logic until the new M1 Max with its super fast internal drives arrived. That is backed up daily to a separate 5TB external Time Machine drive.

And finally for long term storage and archive I have something like 40 TB of RAID 5 storage, with each array being duplicated so there are two arrays, each with the same data and each of which that can lose a single drive and still have the array rebuilt.

No drives last forever but some configurations are more prone to risk so you need a thought out strategy to guide you to making the best choices.
