How fast is ssd?

Most SSD users agree that an SSD is significantly faster than a conventional magnetic harddrive. Especially IO (Input/Output) intenisve operation benefit from the speed of an SSD drive. Such operations include starting up the operating system, starting programs, and reading large files from disk.

There are benchmarks that can test the speed of a harddisk in various areas, such as sequential read and write speed and random read and write speed. SSDs used to perform poorly in randomly writing data, but that problem has been solved in the passed years.
