Memory on a shoestring?, 2003-11-20 Comment: The Viking Interworks(TM) SecureDigital card was supplied free with my HP PhotoSmart 735 digital camera as an Amazon-only deal. The card is capable of storing 59 photos at standard resolution (39 at highest settings) or around four minutes of video. The card itself is compatible with any SD-enabled device including palmtops, MP3 players, and other digital cameras.
I was somewhat disappointed to find that the card was supplied without any accessories whatsoever - I was hoping for a plastic case to store it in when it was not in the camera (such as Bytestor Solutions provide). However, if you'll be storing it in the camera all the time this isn't a major flaw.
If you're looking for a good card with the SD-specific locking feature (a small switch that makes the card read-only, so you can't delete any information by accident) then you could do a lot worse for the money.
