An SSD has rich internal parallelism for data processing.
In comparison to HDDs and similar

An early—if not the first—semiconductor storage device compatible with a hard drive interface (e.g. an SSD as defined) was the 1978 StorageTek STC 4305, a plug-compatible replacement for the IBM 2305 fixed hard … See more

The key components of an SSD are the controller and the memory to store the data. The primary memory component in an SSD was traditionally DRAM volatile memory, but since 2009, it is more commonly NAND flash… See more

The size and shape of any device are largely driven by the size and shape of the components used to make that device. Traditional HDDs and optical drives are designed around the rotating platter(s) or optical disc along … See more

Making a comparison between SSDs and ordinary (spinning) HDDs is difficult. Traditional HDD benchmarks tend to focus on the performance characteristics that are poor with HDDs, such as rotational latency and … See more

SSDs have very different failure modes from traditional magnetic hard drives. Because solid-state drives contain no moving parts, they are generally not subject to mechanical failures. Instead, other kinds of failure are … See more

As of 2009, the cost of HDD storage was so much less that SSD was generally only used for applications where storage speed was mission critical. At that time, researchers predicted that cost would fall and adopti… See more
