*"Clean" cards were overwritten with zeros, partitioned and high-level formatted prior to D30 testing. Before "Dirty" card testing commenced, cards were first filled with a random collection of large and small D30 JPEG and RAW files, then files were randomly removed using the camera's Delete function.
**This card was not tested because it had to be returned to its owner earlier than anticipated.
***This card contains special firmware designed to shorten the Nikon D1's wake-from-sleep time with Lexar Media cards. This firmware should not affect performance or compatibility with the D30.
