PNY's Optima Pro Secure Digital cards perform at a substantially higher sustained write speed (20MB/sec) than standard SD cards. This reduces click-to-click time, so you won't be waiting for your digital camera to catch up with the action and can fire off shots faster. The Optima Pro cards are expressly created for high-end digital cameras that can maximize their performance with this improved technology.

• 133X (20MB/sec) sustained read and write speed
