Oh, yeah – with AE cache i meant the media cache, for previewing in AE. Sorry for the confusion!
I know how the fusiondrive works in theory, but its a little unclear what it really does and I want to have my source files, system/apps and media cache on different drives as this improves speed. Thats why I have to go with an external SSD. Or maybe an internal SSD with a thunderbolt case or something like that.
Its just that the Samsung T3 seems quite nice and is not very expensive.
Thanks for your answer, I’ll probably get it and just try it out. If its not good enough I could always exchange it with a 850 in a thunderbolt case.
