The hard disk interface of K53SJ motherboard supports SATA3.0. If the original hard disk is removed and replaced with SSD with SATA3 interface, the specific transmission speed cannot be given because there is no machine test. Generally, it can reach about 400m m, and the transmission speed is related to the main control chip, flash memory particles, firmware, machine system and driver of SSD. It is generally recommended to choose a better brand, such as Samsung. In order to ensure the success and compatibility of the replacement, it is suggested that you can buy it in a physical store, so that you can test it on the spot and see the specific results. It is also safer to buy.
