A optical drive are drives that have lasers. these lasers are used for CD,DVD and blue-rays. Blue-rays work differently because they use blue lasers to scan the devices. Blue-ray also can run HD CD. These are storage devises and an input device. the normal optical drives produce more laser also blue-ray lasers has a better laser also it can play DVDs and CDs in high definition. An HDD/hard disk drive is an storage device used for storing data and retriving data. These have fans that are plugged in to a device for example computer. However SDD (solid state drive) are more recommended than HDDbecause SSD takes less space in the computer than a HDD.
