External drives require additional controllers to adapt the signals to the chosen interface. The drives themselves are manufactured as ordinary IDE or SATA drives, and are simply placed in an enclosure. The enclosure adds a great deal to the cost.
Another factor is that external drives are more prone to damage, so the company may need to charge more to offset RMA costs.

External floppy drives use additional hardware to connect to a computer, whereas an internal floppy drive uses a simple cable to connect to components already integrated into most motherboards until very recently. Another factor is that external USB floppy drives are a seldom-used item, whereas an internal floppy drive could be leftover stock from when they were a common commodity in every computer.

External drives are easier to transport from computer to computer than internal, but generally cost much more for the same amount of storage space, and transfer/access files more slowly than an internal drive. (Copying things to and from an external take longer than your regular hard drive.) Internal drives are cheaper than externals for the same storage space, and respond more quickly, but can be difficult to install without help or experience working inside your computer. They can also pose problems when trying to transport them and connect them to others' computers, although in general it is possible to do so. So: externals are better for storing data that you'd like to share with people easily, while internal is better for the main storage of information on your desktop computer.
