The main difference between the two is speed (as mentioned before). SanDisk Extreme Pro memory cards offer UHS-II speeds (up to 300MB/s) and are physically different (will get to that part here in a minute). The UHS-I version of the pro card is 170MB/s (and significantly less expensive). Card. SanDisk Ultra.I recently installed a 64GB SanDisk Extreme Pro in my RAK 2.0, and it seems to be working well so far. One thing I will note is that I had some issues pairing with the Helium app after installing this card. It would state "Hotspot miner is unable to respond to requests. Please reboot the hotspot and try again later." Saw the Sandisk Extreme and the Extreme Pro and wondered what the difference is and if that difference is worth it for what I want to use it for. The only difference I can tell is that the Extreme is gold and has 160 MB/s, and the Pro is black and has 170 MB/s (which seems like a very minor difference) Edit: And I just found theres also an
Most speed classes deal with write speeds to SD cards. Its much easier to get faster read speeds compared to writing quickly to an SD card. So, if you're only concern is opening a PDF file, I'd guess that the rendering engine will be more the bottleneck compared to the actual data transfer speed. 1. TheFakeBigChungus • 1 yr. ago.
