Very fast

I loaded these into my Canon R62 and was able to fire off a 35 exposure burst at ultra high speed and review the images almost immediately. Read speeds to my MacBook are very fast also.

Best you can buy!

These cards are awesome and for the value you get two. I shoot almost everyday and have never had an issue.
