Difference between HDD (Hard Disk Drive) and SDD (Solid State Drive)

HDD (Hard Disk Drive) also is known as fixed disk uses magnetic tape for the storage of data.  HDD has a moving read/write head to access data from storage like a gramophone player and slower to read and write. Unlike HDD, SSD (Solid State Drive) has no moving parts, and it obtains data from storage instantly. SSD can give fast performance than traditional magnetic-based computer storage devices. Although both of them perform the same task i.e. both are used to store data, both are used to boot the system, both are I/O devices, there is a spring difference between these two concepts as they utilize different technologies in the storing of data. The difference between SSD and HDD is that SSD stores data in flash memory, enables quick loading and processing, whereas HDD stores data in moving parts, which makes running and processing operations slow.

SSD data will still be retained when the system is powered off. SSD utilizes a grid of electrical cells to transmit data. SSD enables data transmission at a quicker rate with speeds significantly more than a traditional drive. This increases the overall performance of the system. Let’s see the major difference between HDD and SDD.
