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.
|1. SSD is an abbreviation of Solid-State Drive.
||1. HDD is an abbreviation of Hard Disk Drive.
|2. The time for reading and writing the data in SSD is shorter.
||2. The time for reading and writing the data in HDD is longer.
|3. There is a lower latency in SSDs.
||3. There is a higher latency in HDDs.
|4. Solid State Drives supports the more operations of input/output per second.
||4. Whereas, Hard Disk Drives supports fewer operations.
|5. Because the SSDs do not have a rotating disk and motor, the weight of these storage devices is light.
||5. The weight of HDDs is heavy.
|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.
