This is the third of this type I have bought and they have proved to be reliable for video work. In particular they are easily fast enough to record 4K 50p video continuously, although they may not cope with the very high bitrate 4K modes in the latest DSLRs.

I'm a fan of Sandisk. Their products are just great and this one is really top. With amazing writing speed and all. Great price for the card. Love it.

B&H delivers in excellent time, have just received CF card today, had to be formatted in camera before it would show on computer, took 22 minutes to copy 25 images to desktop file, very slow for a high speed rated card, images are from Canon 5DMK4 so they are large but lesser cards appear to copy...

Received product promptly, great product used in my photography
