I've read your other thread and I think you're going a bit overboard.
There are a lot of products in videography that are marketed as workflow streamliners; but crowbarring more and more of them into your workflow has the opposite effect.
The FS100 records AVCHD internally, and if you're going for a natural look that will probably yield an acceptable image. ProRes is the next step up, but considering uncompressed seems pretty ridiculous to me. If you want a recorder with a screen, take a look at the
Sound Devices PIX 220.
Whilst I'm here I'll give you my thoughts on your other thread. I think you've made that overly complicated too, which is particularly disastrous for a back-up strategy. What I'd recommend is:
OS Drive
OS Clone (single-disk FW800 external)
Scratch (FW800 hardware RAID5)
Working Back-up (single-disk FW800 external/iMac second internal)
Archive A (single-disk FW800 external)
Archive B (single-disk FW800)
The OS Clone and the RAID parity of Scratch minimise potential downtime and frustration; but don't consider them back-up. Instead, as soon as you get back from a shoot, copy your video to Working Back-up, and as you edit save your project files and any original media you create during the process as you go.
Once you've finished a project, copy project files, original media and master to Archive A and B, and delete from OS Drive, Scratch and Working Back-up.
Using two separate drives for archive means you can keep them in two different locations, and copying files separately to each from the source leaves you less at risk from Silent Data Corruption and bit rot than RAID1 would.
You can substitute FW800 for Thunderbolt as devices become available.
