At 266X write speed – that’s 40MBps max – the Sandisk Extreme IV CF card is currently one of the fastest writing memory cards for use in digital cameras. Sandisk claims to be using improved parallel processing to get data into and out of the flash memory cells.
The Extreme IV also bundles with the company’s Extreme Firewire 800 card reader, capable of up to 800MBps, for a truly stellar combination. But beware, if your camera is a bit old, these speed demons might not be for you.
