A:AnswerYes, I use for the purpose to store movies and photos as to using a card reader to view on my Samsung big screen TV. Files are transferred from phone, to notebook; organize on notebook and then back on the memory card. Very convenient.
A:AnswerI have bought many of these Samsung EVO memory cards from Best Buy and have used them in Canon 70D & 80D as well as Sony a 5100, a 6000 and a 6500 cameras and have reinserted into an iMAC 27 with no problem. I have not switched them from camera to Samsung Galaxy S9+ or vice versa and it would probably be a good idea to reformat between the two. Switching card from Canon to Sony automatically allows for compatibility and have had no problems switching back and forth.
A:AnswerShort answer, yes. The big question is what you want it to do and how fast of speed is adequate - or too much. If the card you purchase is super fast, and what you want it to do would be fine with a slower speed card - you've spent to much.
