How important is USB 1.1 versus USB 2.0?
Consider the pros and cons of using USB 1.1 and USB 2.0 in terms of speed and cost. Speed: The fastest and latest revision of any specification is normally considered necessary to compete on the retail shelf. This is commonly referred to as the spec game where customers compare specs, and purchase on the basis of maximum specification comparative to other competing readers in the same shelf space. This is particularly true for external peripherals that are not part of the overall computer system. While the speed benefits of USB 2.0 are clear, OEM system manufacturers that use internal readers may benefit from USB 1.1 readers as offering the best value for money. The average speed difference between USB 1.1 and 2.0 for normal media cards is 15-20% for write functions, and can be up to 100% on read functions. Some accelerated write media cards offer better file transfer speeds but nowhere near the 40 times faster speed that USB 2.0 offers over the typical USB 1.1 bus speed. For internal
