I'm looking for a new external harddrive. For some months I've been editing on Premiere CS6 using a Macbook Pro non Retina (you probably know the drill: i7 2.6 8Gb Ram and 750 Gb HDD). The footage is in 2.5" USB 3.0 Western Digital HDDs which I know is a suboptimal solution but I normally have all the HD footage (mostly GOP1 and GOP3 from a hacked GH2) on one track and playback is smooth 90% of the time. Since things are not always going to be that simple and Lightroom (which I also use profusely) would certain benefit from a faster harddrive I'm thinking about buying one. Caldigit has some solutions that are expensive but seem sturdy and reliable. I have my eyes on the AV Pro wich they sell on HDD and SDD flavors with USB3.0 and optional Firewire. They claim that with the UASP USB 3.0 protocol the SDD option can reach speeds of 430 Mb/s on new Macbook Pros and 200 Mb/s for the HDD option. There are a couple of reviews around the web that seem to confirm that. Normally manufacturer's speed claims are not reliable at all, so one can't never be sure. But, if we were to trust their speed claims, these are my questions:

Do you think that the SSD option is overkill for my current setup? Should I be better spending the premium on more storage? (The 4TB HDD option costs more or less the same as the 256 SSD one.)

Here's the product page:

By the way, I live in Berlin so the fact that Caldigit has a European Store is a plus (the dreaded customs and whatnot). That's why I ignored some other nice options out there. Of course if you know of other offers here in Europe, they will be more than welcome!

Thanks!
