The classic floppy disk has within its features a very positive aspect and a very negative one, as well. It has the least capacity of all the storage media, however it is the least expensive. The device, itself, is also the least expensive of all of the storage devices. The floppy disk has a capacity of 1.44 megabytes and costs about thirty cents per disk. The floppy device costs between forty to ninety dollars. A floppy disk is “a round piece of flexible mylar plastic covered with a thin layer of magn

Another type of storage media is the hard disk. The hard disk comes in two varieties: removable and fixed. Both offer fast speed. The devices cost about the same, $150 on average, however the fixed hard disk is more susceptible to theft or damage. The removable hard disk is safer, because it can be removed and kept separate from the computer. The fixed hard drive, however, does offer a larger capacity, an average of forty gigabytes. The removable hard disk offers only about 2.2 gigabytes. The hard disk utilizes the read-write head, similar to the floppy disk. The hard disk device positions the head using a controller. Ultra ATA (AT attachment), EIDE (enhanced integrated drive electronics), and SCSI (small computer system interface) are the most popular types of drive controllers. The hard disk platters are divided into tracks and sectors. A vertical stack of these tracks is a cylinder, which is the basic storage bin (Parsons and Oja 42).

The zip disk and the superdisk, which also use the floppy disk technology, is an alternate means to the floppy disk. These have a larger capacity than the floppy, with the zip disk capable of storing 100 or 250 megabytes of data, and the superdisk containing a 250-megabyte capacity. These s
