Lexar  40x High Speed Series, Compact Flash Memory Card

Lexar Media's Professional Series CompactFlash is designed to speed up image transfer times by taking advantage of a Digital SLR camera's high-speed processor. Capable of sustained write speeds of 6mb per second, making our CompactFlash cards ideal for any photographer who demands optimal performance from the card and camera they use.
