Back when I first got the MK III I had commented on another users post that the 64GB Sandisk card included was too slow to meet most of the video requirements. The OP was using the ProGrade Gold cards and mentioned the same thing you said. The Cobalt series might be better suited, based on the stated speeds. I haven't had any issues with the Delkins at 4k60, though those have all been short clips as I don't really focus on video.I have a 1TB from prograde digital, and it’s not fast enough for RAW video recording. It’s pretty annoying!
Current cards with 1tb are around 600€. Usualy the price is pretty much linear, so I guess around 1200€.How much is it going to cost? $2000? lol
Not silly at all! I just do something different. I take backups in portable devices daily and continue keeping the photos on the card. So on my vacation I have 2 copies. When I come back I copy them again to disk(s) and then I am free to format the card(s).Interesting, this has to be oriented to cameras like the R5 with 8K video I am guessing.
I generally download my photos after a shooting session (Walk in the yard, short day trip or the beach etc.) I just would not trust keeping a months worth of photos and more on the card and something get screwed up on my part, the camera or the card and lose it all.
In fact on vacations I carry several cards and sometimes change them out more than once in a day as I visit several sites for the same reason then download at night.
Might seem silly to some but mistakes happen.
