All digital cameras allow the user to set the compression level. A large majority of the digital cameras on the market allow user to store their images in the internal memory or on an interchangeable memory card. SmartMedia is cheaper for same sized card but it is available in two versions 3.3v and 5v which are not compatible. SmartMedia is easy to damage and requires OS driver support. Floppy disks can also be used on Sony's Mavica camera range.
Floppy disks are available anywhere, very cheap to purchase and guarantee easy access to the images.
All image storage media have their advantages. Choose the one that suits you best. As your needs evolve, a digital camera should evolve with you therefore accessories can be very important. It is important to check the content of the camera before any purchase. Make sure it includes all the required components to make it work as standard.
