PNY's Optima Pro Compact Flash cards perform at a substantially higher sustained write speed than standard Compact Flash cards. The result? Reduced click-to-click time so you won't miss any of the action! This means that you can fire off shots on your digital SLR more quickly, without waiting for the card to catch up as it records your image data. PNY Optima Pro cards are expressly created for high-end digital SLR cameras that can maximize their performance with this improved technology.
Improved click-to-click performance with 133X (20MB/sec) or 266x (40MB/sec) sustained read and write speeds
More than twice as fast as PNY's standard CF cards
