There are two kinds in common use:
molex for IDE devices and sata power connector for SATA devices
IDE
A Molex Connector connects to optical drives and hard drives.
Monitors, Printers, NIC's, Hard Drives can be both, and optical drives.
All PATA (Parallel ATA) drives use the Molex 4-pin power connector. This connector provides the necessary power to the drive, supplying +5V and +12V to operate. The Molex connector is typically used for older hard drives and optical drives before the transition to more modern interfaces like SATA.
To connect an ATA 133 motherboard, first, ensure that the power supply is disconnected. Then, connect the motherboard to the power supply using the 24-pin main connector and the 4/8-pin CPU power connector. Next, attach the ATA 133 hard drive or optical drives using an ATA (IDE) cable, ensuring the drives are set to the correct master/slave configuration. Finally, connect any necessary peripherals and power on the system to ensure everything is functioning correctly.
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.

PATA (Parallel ATA) and Molex connectors serve different purposes in a computer's architecture. PATA is used for connecting hard drives and optical drives, while Molex connectors are typically used to supply power to these drives. PATA drives can be powered using a Molex connector, but they also require a separate data cable for the PATA interface. Therefore, while they are connected in terms of functionality, they do not directly connect to each other.
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.
