1. The bandwidth is different. The bandwidth of 1 is, while the bandwidth of 2 is 3gbs.
2. The technology is different. 2. In the future, some new technologies will be supported, especially NCQ technology, NCQ (Native Command Queuing). 2 can use SSD and support trim, but 1 can't.
3. In fact, it is a habitual saying, and it is SATA that has really become the norm. Therefore, the everyday term "sata2" actually means: But people have become accustomed to saying 2 or, and they have been using it wrongly.
SATA (Serial Advanced Technology Attachment) is an industry-standard serial hardware driver interface that is jointly proposed by Intel, IBM, Dell, APT, Maxtor and Seagate. In 2001, the Serial ATA Committee composed of Intel, APT, Dell, IBM, Seagate, and Maxtor formally established the Serial ATA specification.

The transfer rate is about 300MB s
The transfer rate is about 600mb s
It can be backward compatible, and if you don't use a solid-state hard drive, you can't see much of a gap.

Anonymous users2024-02-05The difference in bandwidth size is only, SATA interface is not so-called, see is 6GB s, this is the interface bandwidth, is the specification, there is a 3GB s is the specification, the bandwidth is only half, if you connect to the mechanical hard disk whether it is or there is no difference, the interface bandwidth can also far meet the mechanical hard disk, if you are connected to the SSD, that can not be connected to the interface, the bandwidth is not enough, the performance of the SSD will be limited by the interface bandwidth.
SATA is an abbreviation for Serial ATA, which is Serial ATA. This is a new type of hard disk interface that is completely different from parallel ATA and is named because of the serial way in which data is transferred.
The SATA bus uses embedded clock signals and has a stronger error correction capability, and the biggest difference compared to the past is that it can check the transmitted instructions (not just data) and automatically correct if errors are found, which greatly improves the reliability of data transmission. The serial interface also has the advantages of simple structure and hot-swappability.

Hello! I'm glad to answer for you, first of all, the net enjoyment series vs the twin series: the net enjoyment series is a single filter fine filter element with pre-PP cotton, and the twin net smart series, the pre-filtration and the rear fine filter element are closely combined, and the pre-filtration system has a greater dirt holding capacity and life than the net enjoyment series, in addition, the twin series is loaded with an intelligent monitoring system, which can check the usage at any time. >>>More
The circle is turned into a standard equation, the center of the circle and the radius r are obtained, and the distance d from the center of the circle to the straight line is obtained. Compare the magnitude of d and r to obtain three positional relationships between a straight line and a circle. >>>More

It has something to do with coffee beans, and these are normal. Because coffee beans themselves are acidic fruits. If it is particularly acidic, it is a problem with the quality and roasting of the coffee beans. For example, Brazilian coffee has a sour taste. >>>More
