Solid state storage (SSS) is a type of storage media in which data is stored electronically instead of mechanically. The solid state storage doesn’t contain any moving mechanical parts, this improves the speed at which the data is transferred to and from the storage media.
There are three types of Solid state storage:
- Solid state drives (SSD)
- Solid state card (SSC)
- Solid state modules (SSM)
Since Solid state storage doesn’t contain any moving mechanical parts, it reduces the possibility of failure and increases the lifespan of the storage media. It also provides data consistency and integrity and requires less power as compared to its electromechanical equivalent. The Solid state storage has a lower latency since it has no seek time, which makes SSS considerably faster than an HDD.
Generally, Solid state storage are used as primary storage, but this will drastically increase the overall cost of the system, since an 1TB HDD costs less then 100€, and an SSS of equivalent storage capacity will cost you a fortune. Keeping that in mind, Solid state storage can also be used as cache, which will define a new layer between the processor and the storage. This will tremendously increase the speed at which the programs and files are loaded, if stored in the cache.
