- At the moment this is the cheapest card for recording 4k 100mb. Sony 6300 does its job perfectly.
- Average write speed. Writing the full buffer of my camera (60 shots at 24mp resolution) to a memory card takes 25 seconds. If you are a reportage photographer shooting series, then this memory card is not for you. According to tests, it gives out 85 for reading and 35 for writing on average, which rests on the minimum allowable numbers of the V30 standard. I took two cards at once, one of which fell apart after a year of use by itself. In principle, not critical, superglue to help. Recording slowed down several times for no good reason, formatting and resetting the camera firmware helped.
