There are two kinds in common use:
If it's an IDE drive, it will use a 4-pin peripheral power connector, often called a "Molex" power connector, Molex being a major manufacturer of these types of power connectors. If the drive is a SATA drive, it will use a standard 15-pin SATA power connector.

A Molex Connector connects to optical drives and hard drives.
Monitors, Printers, NIC's, Hard Drives can be both, and optical drives.
Hello, Currently we do not have HDD with fiber optic connector on board, but this can be expected in future. Intel has already developed a chip which uses optical interconnects instead of copper and carbon nano tubes. When this technology is perfected, all the devices even the USB will be optical.
Disk storage devices are most commonly used in personal computers as a means to enhance memory. The most common are hard disk drives, optical disk drives, and even zip drives.

The purpose of secondary memory is storage of data that is not immediately needed for processing by the CPU. Examples of secondary devices are hard drives and optical drives.
San's or Storage Area Networks are the devices used when making optical drives, or storage drives, such as usb flash drives. You can purchase these from companies like New Egg.
Serial ATA (SATA) is a computer bus interface that connects host bus adapters to mass storage devices such as hard disk drives, optical drives, and solid-state drives.
to connect storage devices such as hard disk drives to a PC
Typically EIDE cables connect to IDE Hard-drives and optical drives such as CD and DVD Drives. The cable connects between the motherboard of the computer and the hard-drive or optical drive. Normally most motherboards have two idea buses. You can have to drives per cable. So a total of 4 drives.
