I shoot a lot of 4K timelapses and this card has never once stuttered on buffering—the V30 rating clearly holds up in practice. Over 400GB of footage stored without any corrupted files so far, which is a huge relief.

I was a bit worried about filling up 512GB on my camera, but this card handles continuous burst shots without any lag. The write speed has been consistent even when I’m shooting long 4K clips, which is exactly what I needed for my travel projects.

This 512GB card handled my drone's 4K footage without a single buffer issue, even during long flights. I’ve filled it with over 200GB of files and the transfer speeds stayed consistent.
