Review on 💯 Reliable Performance: SanDisk Extreme 64GB Compact Flash Memory Card (B00EZE6V50) by Dennis Wood

I bought 2 of these cards for professional use (weddings) in a pair of Canon 5D Mark III cameras. All my cards are Sandisk and I've never experienced a card crash *knock on wood*. Every year or two I buy new cards that are bigger and faster than the previous ones as the price of flash keeps coming down and I throw away the older smaller cards. The transmission speed is excellent. These cards are twice as fast as previous generation Extreme CF cards. I don't often shoot video with DSLRs, so I can't comment on their use in video recording. I am very satisfied with these cards and hope that they will be used reliably for many years to come.
