Storage and InterfaceThe C-3020 saves its images and movies on SmartMedia cards, and a 16MB card comes with the camera. Accessory cards are available separately with capacities as large as 128MB. Though you can use any third-party SmartMedia memory cards with the C-3020, the camera's Panorama shooting mode is only available when an Olympus brand card is inserted. SmartMedia cards can be write-protected by placing a small sticker in the designated area on the card, and a set of stickers is included with each memory card. Stickers can only be used once, as they must be clean to be effective. You can write-protect individual images on the card via the Protect button on the back of the camera. Write-protection of individual images prevents them from being manipulated or erased (except through card formatting, which erases the entire card).
Five image sizes are available for still images, including 2,048 x 1,536; 1,600 x 1,200; 1,280 x 960; 1,024 x 768, and 640 x 480 pixels. Files can be saved as uncompressed TIFFs or as JPEGs with high or normal compression ratios. Movie files are saved as Motion JPEGs, at a resolution of 320 x 240 pixels.
The table below outlines the approximate number of images that can be stored to a 16MB SmartMedia card, as well as their approximate compression levels.

The C-3020 comes with a USB cable for connecting to a computer, and a software CD contains drivers and interface software for downloading images. Download time for a 9.5MB file took 21.9 seconds, at a transfer rate of about 432KB per second. This is on the fast side of average among USB-connected cameras I've tested.
