SSD is a non-volatile storage device, which stands for Solid State Drive. SSD stores the data on flash memory chips and maintains the data in a permanent state, even when the power is off.
Sometimes, this storage device is also called as a solid-state disk or solid-state device. As compared to electromechanical drives, SSDs have lower latency and access quickly. These storage devices store the data in the semiconductor cells.

6. In the SSDs, the transfer of data is not sequential |
6. In the HDDs, the transfer of data is sequential. |
7. This storage device does not produce noise. |
7. Due to the mechanical movements, HDDs produce noise. |
8. The size of the SSD is more compact. |
8. The size of the HDD devices is larger. |
9. As compared to Hard Disk Drives, Solid State Drives are more expensive. |
9. The devices of Hard Disk Drives are cheaper. |
10. SSDs are safe from the magnetic effect. |
10. In HDDs, magnets can remove the data. |
11. SDDs generates little heat because there is no moving part included. |
11. HDD devices generate more heat because of the mechanical part. |
12. It consumes less power than the HDDs. |
12. HDDs require more power to keep all the parts moving. |
13. The average boot-up time of OS is 10 to 13 seconds. |
13. The average boot-up time of OS is 30 to 40 seconds. |
14. The file opening speed of SSD is 30% faster than the HDD. |
14. The file opening speed of HDDs is slightly slower. |
15. As there are no moving parts, so there is no vibration. |
15. Due to the spinning of platters may results in vibration. |
