The full form of SSD is "Solid State Drive". In terms of functionality, it is very similar to a hard disk drive (HDD), a mass storage unit. It allows data to be read and written and keeps stored data in a permanent state without power. SSDs are also identified as solid-state drives or flash drives and can be connected to a computer through conventional IDE or SATA connections.
- SSD is non-volatile storage.
- SSD is equipped with FGR (Floating Gate Transistors) to store electrical charge.
So, even though it is not connected to the source, it stores the data. In an SSD, each FGR contains one bit of data, which is marked as 1 for a charged cell and 0 for a cell with no electrical charge required.
Various SSD components
The components of an SSD are flash memory chips and flash controllers.
- Flash memory chip: Information is stored on a flash hard drive containing a storage disk. An SSD has interconnected flash memory chips that are made of silicon. So, to achieve different densities, SSDs are developed by stacking the chips into a grid.
- Flash Controller: It is an embedded microprocessor that handles operations such as information retrieval, error correction, and encryption. It also monitors the control between the SSD and the host computer for I/O (input/output) and R/W (read/write) functions.
Advantages
- It is more reliable than a hard drive because there are no moving parts that can break down and generate heat.
- Since it contains no moving parts, it provides faster startup, quick loading of apps and improved device responsiveness.
- It is thinner and lighter than a hard drive, which makes it more resistant to wear and tear.
- Since it has no moving parts, it requires less energy to operate.
- Anyone could install an SSD with nothing more than a screwdriver - with no prior experience.
- It is configured for both sequential and random data requests to provide good write and read efficiency.
