ODD (Optical Disk Drive)
It is an advanced technology for data storage. Optical Disk is a disk read and written by laser beam. Optical disk does not need to move access arms and read/write heads, because a laser beam can be moved electronically. For writing data, a laser beam burns tiny cavities into the surface of a disk to mark bits for data. To read the data, a laser beam scans these areas.
Hard Drive
Drive is the main location where all data is stored. Most Hard Disk drives consist of spinning platters of aluminium, glass or ceramic that is coated with a magnetic media. Harddisk is used to store huge amount of data permanently.
Hard Drive available in the market to store the data like 80GB, 160GB, 250GB, 320GB, 500GB, 1TB, 2TB, 4TB, 8TB, etc.
