I keep reading that you like the idea of running a 3 disk mirror for backup. I can see where that is fine... but I am having doubts as well.
Let me explain my setup. I have a 4 disk (3 TB each) raid 5 running off of thunderbolt (except the scratch volume). I actually have 4 Volumes: Scratch, Photos, Music&Videos, and Boot. The Boot Drive is a Clone of my Macintosh HD (MacBook Pro 13", 2017). Boot Clones once a month using CCC. The Music&Videos is my iTunes library and MKV files (I may move away to another video server someday...). The Photos disk is all of my photos and some videos that I have done for clients. The Scratch disk is Raid 0 for LR and PS scratch files, although, I think some are still on the MBP SSD. I am a little paranoid about wearing out that SSD, since it can't be replaced.
I am using CCC to clone the Photos and Music&Videos volumes to USB drives. I am using 2 USB drives, one goes to offsite backup. I am also using TimeMachine to backup Macintosh HD and most of Photos to another USB drive. TimeMachine is kind of cool, but at times, I don't trust it. Like yesterday... it just decided to apparently backup everything again. At least the used space almost doubled. CCC runs at 2:00am to backup Photos and Music&Videos. When I import a batch of photographs or video... I manually run CCC.
What do you consider the main advantage of running the 3 disk mirror of the CCC backup?
Thanks!

We recommend that users understand that you can never have too many backups.
It appears that you are protecting yourself fairly well.
The main advantage of a 3 disk backup is keeping one disk off site and rotating it occasionally. This means you always have a "snapshot" available in the event of an emergency. Inexpensive insurance. You never know these days, from ransom-ware to Hurricanes, what can happen.
