I dunno man...

For the tremendous cost, you could go with a thunderbolt SSD and get MORE storage. For example, run the 512SSD, and then for $500, get yourself a 512GB thunderbolt SSD. Your video files and the like can go on the external SSD, which will be off-the-shelf upgradable later on. It'll be nearly as fast as the internal drive thanks to thunderbolt.

Or, again for $500, you could also do a RAID setup (like the G Raid). I work with large image files (photography) and I do not like having just one copy of anything. No sir. Especially if you're making any money at it. I'm not going to waste my time on images I only have ONE copy of. Hard drives fail. External RAID enclosures are great because you can plug them in and have a copy of everything (run it in RAID 1, so two 1TB drives become a 1TB RAID setup, but if a drive fails you don't lose a thing).

It's not always very portable though. Personally, I carry around a 2.5" spinning hard drive (would love to upgrade to an external SSD), and when I pull images off the cards, I copy them to the internal SSD on my MBP, AND to the external drive. When I get home, they go on to a RAID setup, and then I'm free to delete files from my laptop or external drive to save space. I also do backups of the RAID unit for triple-redundancy.

But, even redundancy aside, you could get MORE storage for LESS money going with the 512 and an external 256-512GB SSD (or WAY more storage with an external spinning disk). I just don't see a lot of value in the 768GB drive, not with two thunderbolt ports on that thing.

Personally, if I were in your shoes, I think the 512 is plenty for most uses. With large video files, I'd go for a good external 1TB or so spinning drive. Not as fast as an SSD, but tons of storage. I would then just move whatever files I was working on over to the SSD, voila! A 1TB spinning USB 3.0 drive is peanuts compared to what you're wanting to spend. (Personally, I wouldn't go for a spinning thunderbolt drive. Spinning drives don't saturate USB 3, much less thunderbolt, so it's a waste of moolah, but TB would be nice for an external SSD!)

I went for 768 just because my previous desktop (that this was replacing) had 512SSD and 2Tb secondary drive. I thought I'd be struggling, but I'm not. I probably could have got away with a 512 at a push - I'm about 250Gb free at the moment, but it would have required constant checking of file sizes and I can't be bothered.

You can't compare external storage with internal -- anything external isn't going to be there half the time, so you can only do backup stuff on it, and for that you're better off with a NAS.
