SSD (Solid state drive SSD, English) or SS great is a type of data storage devices, which use the total circuit chip as a memory to store the data permanently, just like a hard disk. The technology of the solid state, SSD, built to replace a hard disk interface. Input/output are identical and can be used interchangeably, and because the SSD is built with electronic circuits, so no mechanical parts, any movement (the principle of hard disk and the disk is using the papi topped magnetic plate rotate). Result in damage from the impact of solid state SSD hard drive is less than (or resistant to vibration) by comparison to the SSD does not need to rotate the magnet plate to read data make the device less power and data access (access time) and time delay (latency), less because it can access the data in different locations quickly and immediately, without waiting for the rotating magnetic plate, to the position of the data.Word that the SSD is a broad word that describes the storage device the same way as a hard disk, but the memory used to store the data using a magnetic plate replacement. Solid state, SSD, so there are many types, which vary according to the type of memory used to store data. Current memory used in solid state, SSD is the Flash memory. Which is most common and the most popular, but there are disadvantages that limit the number of times data is written and another type of DDR SDRAM is from SS or RAM that is used as the main memory in a computer, that we already know, which is much faster than Flash memory and overwrite is not limited, but?DDR SDRAM is the youthfulness that temporary memory so that it will act as a permanent memory, it must have a permanent power source to not make forget information. With this restriction, so they are not as popular in common usage by households, but popular in the industry, high-performance data storage.
