Zip drives are high capacity magnetic disks which are removable and can also be read or written. ZIP disks are almost same to floppy disks, they are much faster, and have a much great capacity. The floppy disks can hold at the max of 1.44 megabytes, Zip drives comes under two sizes, which is of 100 megabytes and 250 megabytes.

Most of the ZIP drives are confused with the super floppy, which is a 120 megabyte floppy drive which can traditional handle 1.44 megabyte. Zip drives are a higher capacity, higher performance drive. Zip drives were first introduced at a very low memory capacity which was of 1 gigabyte and 2 gigabyte sizes.

ZIP drives can be internal or external unit: The Zip drives which is provided for the small computer standard interface is the fastest, sophisticated, expandable, and expensive type of configuration. It is important to connect or disconnect Zip drives from the bus while the computer is running. If you the maximum performance of the Zip drives an easy setup the SCSI interface.

This will probably require a SCSI adapter, to most of the PC for high-performance to have built-in support. Each host adapter can support either 7 or 15 SCSI devices, depending on the model. To support Zip drives, the operating system should have a driver which has a particular host adapter, and a generic driver for each type of device such as SCSI disk driver, SCSI tape driver, and so on.

There are devices that can be better utilized with specialized drivers but they tend to work with the Zip drives, too. Using a zip drive can be used for determining which device file or directory represents the ZIP drive. This can be determined by looking at the boot messages while you will see a line something like this: da1: Removable Direct Access Device. The ZIP drive is represented by the file which is supported by the IDE interface at a low cost disk drive interface which is used for desktop PC's.

The Zip drives are internal and can be used for performance of ZIP drives which is comparable good to ZIP drives. The drawback of the interface is the limitations it imposes. Most adapters can only support 2 devices, and Zip drives interfaces are not typically designed for the long term. The original Zip drives would not support hard disks with more than 1024 cylinders, which is forced to upgrade hardware. You can expand your PC by adding another disk, a tape drive, you may invest drive to avoid problems in the future of the Zip drives. Zip drives are prefixed with an IDE hard disk and so on.

The parallel port interface of Zip drives is popular for portable external devices such as ZIP drives, which is virtually standard parallel port. This makes things easy for people to transfer data between multiple computers by toting around their ZIP drive.

The Performance of ZIP drive could be increased by connecting the drive in parallel port where speed varies between various computers and can often be configured in the system BIOS. Some machines which use Zip drives will also require BIOS configuration to operate in the parallel port which means that parallel ports were originally designed only for output to printers.
