why ssd is faster than hdd ?
Answers
Rather, information is stored in microchips. Conversely, a hard disk drive uses a mechanical arm with a read/write head to move around and read information from the right location on a storage platter. This difference is what makes SSD speed so much faster. ... This is a non-volatile type of memory.
Answer:
SSD stores in semicondustor cells.
HDD has mechanical platters which has to rotate and get the data required where it is not the case with the SSD.
Explanation:
A solid-state drive (SSD) is a solid-state storage device that uses integrated circuit assemblies to store data persistently, typically using flash memory, and functioning as secondary storage in the hierarchy of computer storage.
A hard disk drive (HDD), hard disk, hard drive, or fixed disk[b] is an electro-mechanical data storage device that uses magnetic storage to store and retrieve digital data using one or more rigid rapidly rotating platters coated with magnetic material
