What is SSD ?

Advantages of Solid-State Drive (SSD)

The following are the advantages of Solid-State Drive:

  • SSDs consume less power.
  • The speed of reading and writing the data is faster.
  • The main advantage of SSD is that it produces less noise because SSDs are non-mechanical.
  • Due to the high speed of SSDs, files are transferred quickly.

Disadvantages of Solid-State Drive (SSD)

The following are the disadvantages or limitations of Solid-State Drive:

  • Cost is the most significant disadvantage of Solid-State Drives because they are expensive.
  • Recovery of lost data is not possible.
  • The storage capacities of SSD is also less.

Difference Between SSD and HDD

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 sequential6. 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.

What is SSD

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.

Unlike the HDDs (Hard Disk Drives), SSDs do not have any moving parts. That’s why they are called solid-state drives.

Types of SSD

Following are the several types of Solid-State Drive (SSD):

  • mSATA
  • 2
  • PCIe
  • NVMe
