A hard disk using a SATA interface is also called a serial hard disk. The biggest advantage of SATA is the high transmission rate. Currently, the two mainstream interface types are SATA 2 and SATA 3, but many of them are unaware of the SATA 2 and SATA 3 interfaces. Can these two different interface types be universal?
SATA3.0 is also called SATA 6Gbps, SATA2.0 is SATA 3Gbps, many computer novice friends have the same question, whether the two interface types sata2 and sata3 are compatible and universal problems, in fact, sata3 belongs to the sata2 next-generation upgrade version, which is fully compatible Just like the USB3.0 and USB2.0 relationships, the two are compatible.
The difference is that the two interface types SATA3 and SATA2 have different transmission rates. The latest SATA3 interface can achieve a transmission rate of 6Gb/s, while the SATA2 interface has a transmission rate of 3Gb/s. In theory, the SATA3.0 interface is twice as large as SATA2.0.
