I'm mostly a CF guy, and the only high end SD card I've bought was the 64gb Sandisk that stays in my D800 as a place to dump JPEGs. With that said, I have a D600 on lay-a-way at the local shop and I need to beef up my SD card "collection" as I expect 24 mp RAW files will fill up 4 and 8gb cards quickly(I know I can get about 300 RAW files from my D800 on a 32gb card, so I'd expect about 500 RAWs from the D600 on a 32gb). So, with that in mind, I need to get some big SD cards. I prefer name brands, and a look at B&H seems to show SanDisk as the most dominant of the big names. I'd want to 32gb at least. I'd probably like one 64 or 128gb to leave in the camera for JPEGs, and then a couple of 32s or 64s to rotate for RAWs. The speed ratings do confuse me a bit, though. I don't THINK that Nikon has anything that uses UHS-II(or whatever it's called) so it won't necessarily speed up writing files in the camera. With that said, I DO have a nice Lexar USB 3.0 CF and SD card card reader that can get files off of fast cards fast. So, with that in mind, can anyone give me suggestions on SD cards?
