With the Thunderbolt Cfast reader copying to a solid state drive, copying over 256 GB is actually quite fast. I was on a shoot where the producer had that setup and he was copying 128 GB cards in a couple or few minutes, I'd guess, though I didn't time it. He made quick backups too. Not that one can expect every producer to show up with that setup.

Yes, that's the one I have. So far, works great even though EgoDisk recommends not using it, they say it can corrupt the files. But for location use with a laptop, it's the only Thunderbolt 1/2 compatible reader I could find. The new Sonnet dual Thunderbolt 3 reader looks like the one to buy, IF your laptop supports Thunderbolt 3 (mine is old and doesn't). There is an Apple adapter that adapts Thunderbolt 3 to Thunderbolt 1 and 2 but it doesn't pass bus power, which is how the readers are powered so that's no good. Now I have to solve the issue of my laptop only has one Thunderbolt 1 port and none of the bus powered Thunderbolt SSDs has loop through. So I will probably have to buy one of those Other World Computing Thunderbolt hubs, which adds expense and size to the whole thing. Then again, I don't think our clients are going to spring very often for shooting Cinema RAW Light so for my own stuff, I can wait until I get back to the edit bay to download the cards so maybe having a laptop that can handle downloading RAW is moot point?
I am also buying CFast cards with the hope that come February 2018, Apple will grace us with a usable XF-AVC codec so in that case, I would still be shooting to the CFast cards so I will need to either spend the money for a new laptop or buy a Thunderbolt hub for my current laptop. I wish the prices on the 2TB SSDs would come down, the new Samsung T5 looks amazing but it's $800.00 and it's only USB 3.1 protocol via a USB C connector so that does me no good since my laptop also lacks USB 3.1. Damn new protocols, they never stop, just keep introducing new ones that outdate everything before it, making you buy new computers, cables, drives. When Apple introduced Thunderbolt, they laid out the roadmap for the protocol, it looked good. Then they came out with Thunderbolt 2, same connector, so good backwards compatibility. Now Thunderbolt 3 trashes all of that, they HAD to change the stupid connector, why? All of the new RAIDs, single SSDs, card readers are Thunderbolt 3/USB-C. Frustrating since a nice new loaded MBP costs a small fortune. Okay, enough of my bitching.
