After changing from HDD to SSD, you can make use of SSD’s advantages listed below:

► Faster data access: Without the seek to process, SSD can read data faster than HDD. When your desktop or laptop HDD is replaced with an SSD, it is with higher speed when booting up the operating system or running installed applications.
