Question

differences between hard disk drive and optical drive

Answer 1

Optical drives are hardware devices that are used to read / write storage devices like CD / DVD ROMs. These do not store data on them but use other media to perform the storage. These can store very less data as compared to harddisk drives. These are also very slow as compared to hard disk drives.

Hard-disk drives are physical devices that are used to store data on them. They can be magnetic drives (HDD) or solid State drives (SSD). They store information on themselves.

Answer 2

Answer:

Optical Disk

Optical Disk is again a storage device and use optical storage technology for data processing like read/write/access operations. An optical disk stores data using laser light and is read using the same. Laser light reads data on a spinning disk.

Hard disk

Magnetic storage medium for a microcomputer. Hard disks are flat, circular plates made of aluminum or glass and coated with a magnetic material. Hard disks for personal computers can store up to several gigabytes (billions of bytes) of information. Data are stored on their surfaces in concentric tracks.
