The difference between sata2.0 and sata3.0

- Jun 23, 2020-


sata refers to the hard disk interface on the computer motherboard.


3.0 is an upgraded version of 2.0. It was released in 2009, so the computer motherboards before 2010 basically only provide sata2.0 interface. If you don’t know whether your computer is sata2.0 or sata3.0, think about the time you bought this computer; if your computer was purchased in 2010 and later, the motherboard may provide both sata2.0 and sata3.0 interfaces, you can use hardware detection tools such as Master Lu to further Confirm that the SATA3.0 interface is compatible with 2.0, so if your computer only provides 3.0, you can still use the 2.0 hard drive;


The most critical difference between sata2.0 and sata3.0 is the transmission speed.

The maximum transmission speed of sata2.0 is 300m per second, while the maximum transmission speed of sata3.0 can reach 600m per second. In other words, the speed of sata3.0 doubles;


Is it necessary to buy a computer with sata3.0 interface to buy a computer? Not necessarily, because the SATA3.0 theory supports a speed of up to 600m/s, which does not mean that it can reach 600m/s in actual use, and a very critical factor is the transmission speed of the hard disk, because the sata interface is connected to the hard disk Together, if the maximum transmission speed of the hard disk is only 300m per second, then there is basically no difference between sata3.0 and sata2.0;


At present, the transmission speed of most mechanical hard drives does not exceed 100m, so if you use a mechanical hard drive, you don’t have to worry about interface problems at all; but with the development of technology, solid-state hard drives are increasingly concerned and loved by consumers. The transmission speed may be more than 300m per second, so if you want to use a solid state drive on your computer, it is recommended to choose a sata3,0 computer.
