About the role of SATA hard disk SATA interface SATA connector

The SATA hard disk interface is the connecting component between the hard disk and the host system, and its function is to transfer data between the hard disk cache and the host memory. The connection speed of the computer is related to the SATA hard disk interface. Because different SATA hard disk interfaces can determine the connection speed between the hard disk and the computer, in the entire system, the role of the SATA connector hard disk interface can directly affect the speed and speed of the program. The performance of the system is good or bad. From the perspective of each household, the hard disk interface is IDE and SATA two specifications, each has its own advantages and characteristics, users need to choose according to their own circumstances.

IDE interface hard drives and motherboard interface IDE interface hard drives are generally known as PATA hard drives with parallel specifications. At present, most desktop storage systems use parallel bus interface hard drives called Ultra-ATA. This specification technology is from the 1980s It has been used in desktop systems as the mainstream internal storage interconnection technology. Due to the wide range of applications and a long period of time, mature technology can bring about the low cost and rapid development of larger-scale integrated manufacturing. The large capacity.

Since no changes have been made for a long time, in terms of data transmission, this IDE interface hard disk appears to have some lag, because the current mainstream PATA hard disk can only support two data transmission specifications, ATA/100 and ATA/133, and the highest transmission rate is only It can reach 100 or 133MB per second, which can only meet the current large-capacity hard disk data transmission under general conditions. In addition, the 80-pin data cable used by this type of hard drive is messy inside the case, which will hinder the flow of air in the case, thereby affecting the heat dissipation of the system. Although the disadvantages are obvious, for some old users, because the original motherboard platform does not support the SATA interface, this IDE interface PATA large-capacity hard drive is still the first choice, and some users think that this type of hard drive is technically Mature and stable, so I chose this type of PATA hard drive.

In terms of technical characteristics, it has to be admitted that SATA hard disks are inferior to SATA hard disks in terms of installation, transmission rate and power consumption, shock resistance, and noise. Because the SATA hard disk has a faster external interface transmission speed and more complete data verification measures, the standard transmission rate specified by the SATA1.0 specification can reach 150MB/S, which can give full play to the performance advantages of the SerialATA interface, because of the theory of ATA100 The value is 100MB/s, even for ATA133, the highest is 133MB/s.

In addition, the SATA cable is very convenient for installation, and the most important feature of SATA is to support hot swap. Serial SATA method through better data verification method, low signal voltage can effectively reduce various interferences, thereby more effectively improving the efficiency of data transmission, and the new SATA hard disk cable is also more conducive to heat dissipation inside the chassis .

SATA connectors can bring many benefits in terms of power consumption, ease of installation, hot plug support, internal heat dissipation, and drive configuration. At an economical price, a higher level of excellent performance, high capacity, high protection and ease of use is achieved for external storage solutions. As the storage industry transitions from parallel interface to serial interface technology, desktop PCs, mobile PCs, and storage devices The I/O interface of some server applications has begun to change to serial technology. According to market analysts, the overall sales of serial ATA/SATA connectors including connectors, sockets and cables are expected to reach 903 million this year, compared with 141 million in 2003. As far as the serial interface technology itself is concerned, it has the advantages of reducing cables, increasing data throughput, and improving crosstalk and impedance matching problems. In addition, people's enthusiasm for serial interfaces can also be partly attributed to the vigorous promotion of leading chip and connector manufacturers.

What is the coaxial connector?

图片
Coaxial connectors are used to transmit RF signals. They have a wide transmission frequency of up to 18 GHz or higher and are mainly used for radar, communication, data transmission and aerospace equipment. The basic structure of the coaxial connector includes: a center conductor (a positive or negative center contact); a dielectric material outside the inner conductor, or an insulator, and the outermost is an outer contact, which serves as a shield outside the coaxial cable. The same function of the layer, that is, the signal transmission, the grounding element as a shield or circuit. The coaxial connectors are mainly divided into: SMA, SMB, BNC, TNC, SMC, N-type, BMA, and the like. Male: Male (plug), thread inside, inside is the needle. Such as TNC (M). Female: Female (socket), threaded outside, inside is a hole. Such as SMA (F). RP: Reverse Polarity means that the head and the inside of the needle are opposite. Bulkhead: It is the joint of the lockable screw on the board and...

The optical fiber connector

图片
A fiber optic connector is a detachable (active) connection between an optical fiber and an optical fiber. The two end faces of the optical fiber are precisely butted together so that the optical energy output from the transmitting optical fiber can be coupled to the receiving optical fiber to the maximum extent. It also minimizes the impact on the system due to its involvement in the optical link, which is a basic requirement for fiber optic connectors. To some extent, fiber optic connectors affect the reliability and performance of optical transmission systems. Basic introduction A connecting device for re-plugging between optical fibers, also called a fiber optic movable joint. The main performance parameters (and typical values) are: insertion loss (<0.5dB), plug-and-repeat repeatability and interchangeability between connectors (500 changes). When used in a large-capacity high-speed transmission system, reflection is also required to be small. Introduction Optical fiber con...

The working principle of IDC termination method

图片
Introduction and background IDC termination method is often used in various applications. This termination technology has been successfully applied to a variety of industries where multi-contact mass termination and very economical. Multi-point cable termination can be achieved with insulation displacement  connectors (IDC)  because the termination force is relatively small (usually a few pounds, while crimping is hundreds of pounds). In addition, another advantage of this technology is that it eliminates the stripping operations required in crimping. Therefore, in many electronic applications, such large-scale terminations are often used when using multi-strand cables. In many cases, multiple flat cables are used for this very economical large-scale termination. However, discrete multi-strand cables can also be used to reduce costs because the steps of cable stripping preparation and terminal insertion are eliminated. This type of application provides rapid assembly of high-d...
