Say, RAID-6? That's what you do for drive failures. The problem with drive failure isn't replacing the drive, but the data and the downtime.
With most workstations, this is easy, you can get a RAID controller, usually integrated on the board (Dell's PERC 710s are great) and you can knock in a bunch of drives and go. High performance, high resilience. No such luck on this new Pro.
Another option would be a good external system. Maybe a heavy hitting iSCSI or FC array. That's where you go for really high end, lots of storage, reliability, etc. Ahh well you are kinda screwed there too. No cards to add FC to the pro, and OS-X has no iSCSI initiator, which is shocking for a modern OS, Windows got it in 2003 and Linux in 2005.
Also you might want to look in to SSD failure rates. They aren't particularly high, but they aren't particularly low either. Oh, and they are workload dependent as well. I loves me some SSDs, but don't think they are rocks on which you can build your house.
Your analysis misses a few important implementation details.
First, at least one company (ATTO) already makes thunderbolt adapters for 10GbE and FC. ATTO and SNS makes iSCSI initiators for OSX. I've used both. They work fine. But iSCSI on Mac rarely makes sense.
Second, the typical usecase for these is for a video editor. Few use iSCSI, and the better funded ones will be connecting to a nice SAN or NAS over 10 GbE.
Third, who cares? The SSD fails, you get it replaced. These are workstations, not servers, and any important data should be going to a more redundant system.
