which disk strategy/backup is better?

[hfg]

I have a RiMac with the 1TB SSD internal and am considering how best to add additional disk storage with backup using a ThunderBay IV 4 drive Thunderbolt enclosure.

I desire an additional 3 TB of storage for archive documents, mostly static files, music, movies, and other less active material that doesn't require the speed of SSD.

One slot in the Thunderbay is for a 500 GB Windows BootCamp SSD.

Scenario 1:
2 ea. 3 TB hard disks in RAID-1 mirror for the archive data.
1 ea. 3 TB hard disk partitioned as 1 TB SSD bootable daily clone and 2 TB Time Machine for SSD data only.

Scenario 2:
1 TB hard disk for SSD bootable daily clone.
3 TB hard disk for archive data.
6 TB hard disk for Time Machine of SSD and archive data.

Any advantage of one over the other?
Other suggestions?

This is for active working "quick access" data. I will also have it all backed up to a remote network NAS.

Thanks for your consideration ...

I would do this

slot 1: bootcamp SSD
slot 2: 3TB archive data
slot 3: 4TB clone of internal & archive data (clone daily)
slot 4: 6TB TM of internal & archive data

Why? it gives you two sources of backup for what you care about (your internal and your archive). One source is a complete copy and the other is a rolling copy for file reversion if required.

You can clone 2 drives to 1 drive using CCC (I do it all the time). Just set the flag to protect root level items. Let's call slot 3 clone as ....My_clone

then with CCC setup 2 automatic clones

internal -> My_clone
archive -> My_clone/archive

you just need a folder called "archive" at the root level of My_clone and anything on the archive drive will be put there.

Thanks, that does look like a useful configuration!
