I just got a pocket 2 used off ebay and it came with a 256gb Samsung Evo Plus card with reader, this one to be precise. I did a test video at 4k24 about 2-3 minutes long, for one the video file is 2gb, does that sound about right? And when trying to transfer it to my PC the ETA was about 30minutes, it was only going at 1-2mb/s, does that sound right? I've never really used MicroSD cards before so I'm not sure if it's just slow because it's 4k, or if it's the actual port I'm plugging the reader into on my PC that is slow. I have two different SSDs in my PC so it shouldn't be them. I saw some other cards have an actual USB reader, maybe those are better? Sorry for the noobness
