Explanation:
Detailed explanation-1: -The platter inside the hard disk drive is coated with a magnetic media which records data in binary code (1’s and 0’s). A solid state drive does not contain magnetic coatings. Instead, SSDs rely on an embedded processor, or “brain", and interconnected flash memory chips that retain data even when no power is present.
Detailed explanation-2: -Magnetic devices are fairly cheap, high in capacity and durable. However, they are susceptible to damage if dropped. They are also vulnerable to magnetic fields. A strong magnet might possibly erase the data the device holds.
