    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.
