Solid State Drive (SSD)

Solid-State Drive (SSD) is also known as Solid-state disk. SSD is nothing but, a solid-state device which uses integrated circuit assemblies as memory to save data persistently. Firstly, SSD technology uses electronic interfaces suitable with traditional block I/O hard disk drives, which lets to access simple replacements.

SSDs have no moving elements, which distinct itself from traditional electromechanical magnetic disks (HDD or floppy disks). Comparatively, SSDs are resistant to physical shock, run silently, low access time and less latency.

Nowadays, most of the SSDs use NAND-based flash memory, which is a type of non-volatile memory that retains data when power is lost. Some applications need quicker access but not data persistence after power loss, SSDs may be built from RAM. Those devices use batteries as integrated power sources to retain data after external power loss.

Benefits of Solid-State Drives:

1. PC which has been armed with SSD will boot in seconds like less than a minute. This is because there are no mechanical parts in SSD.

2. Most of the SSD need lower power and generates less heat, which results in low electrical usage and that leads to longer lifespan. This will be so helpful in laptops which are prone to overheating.

3. With no moving parts, SSD do not generate ant noise.

4. SSD is not affected by magnetism.

5. SSD only use flash memory to save data that offers better performance and reliability.

6. SSD is available in 2.5”, 1.8” and 1.0”, increasing the available space available in a computer, especially a desktop or server.


Drawbacks of Solid-State Drives:

1. The price of a SSD is much more than an HDD, that’s why most of the PC with SSD has a few hundred GBs of storage.

2. Most of the SSD use more power than standard HDD, especially when idle, which will drain the batteries of laptops quickly.

3. At present, there are very few large capacity SSD versions, but we can expect it to change in the forth coming years.
