Editor to share with you what are the differences between sata2 and sata3 interfaces in the hard drive. I hope you will gain a lot after reading this article. Let's discuss it together.

The main difference between the two interface types of SATA2 and SATA3 is the different transmission rate. The latest SATA3 transmission rate can reach 6Gb/s, while the transmission rate of SATA2 interface is 3Gb/s. In theory, the SATA3.0 interface is twice as large as SATA2.0.

The hard disk using SATA interface is also called serial port hard disk. The biggest advantage of SATA is its high transmission rate. Currently, the two mainstream interface types are SATA 2 and SATA 3.

SATA3.0, also known as SATA6Gbps,SATA2.0, is called SATA3Gbps. Many computer novice friends have the same question about whether the two interface types sata2 and sata3 are compatible and universal. In fact, sata3 belongs to the next generation upgrade version of sata2, which is completely compatible, just like the relationship between USB3.0 and USB2.0, the two are compatible with each other.

The difference between hard disk interface type SATA2 and SATA3

1. The appearance of the two interface types is different.

Only from the outside, the SATA3 and SATA2 interfaces on the motherboard are basically the same, but many motherboards will be marked with different colors in order to distinguish between SATA2 and SATA3 hard disk interfaces. Most motherboards that support the STA3.0 interface are black, while the SATA3 interface is yellow / white / blue, etc.

SATA2 and SATA3 motherboard hard disk interface appearance is basically the same, many low-end motherboards still use SATA2 and SATA3 dual interface mixed mode, such as AMD platform A75Magi Intel platform B75, H81, B85 motherboards are SATA2 and SATA3 dual interface mixed mode, while some high-end motherboards, such as A88, H87, Z87 motherboards are all SATA3.0 interface.

2. The transmission rates of the two interface types are different.

The main difference between the two interface types of SATA2 and SATA3 is the different transmission rate. The latest SATA3 transmission rate can reach 6Gb/s, while the transmission rate of SATA2 interface is 3Gb/s. In theory, the SATA3.0 interface is twice as large as SATA2.0.

After reading this article, I believe you have a certain understanding of the differences between sata2 and sata3 interfaces in the hard disk. If you want to know more about it, welcome to follow the industry information channel. Thank you for your reading!
