What are the features of SSDs?
A solid state drive (SSD) comprises a controlling unit and a solid state unit. An SSD and a hard disk drive (HDD) have the same interface specifications, definition, functions, and using methods. They are also similar in the form factor and dimensions. The difference is that the SSD has no mechanical part. The SSD has NAND Flash as the storage medium and the data stored on it is accessed through being written and erased in blocks.
The SSD has no mechanical latency caused by the disk medium or motor as the HDD does; therefore it has higher performance, lower power consumption, better shock-resistance ability, and better stability.
