This card is fast. Seems really fast and very reliable. I have it on my A7iii and have never had any issues with buffering or slow loading. The data transfer speed to my computers/iPads is faster than any of my other cards. I would recommend the "Tough" over the regular as it was only about $10 when you bought it. This map is not for everyone. If you have a camera that supports such UHS-II cards, great. If it wasn't for you, I wouldn't even care. Plus, it's ridiculously expensive for an SD card. For the high price, you get a much more reliable card, so you get what you pay for. Like everything at Sony. This is the only reason I bought this item.
