The development and transformation of SATA:
The development of the SATA connector provided by the Taiwan connector manufacturing company is far better than USB viewed from the current situation. It’s mainly because the development of SATA is relatively late and had to stand on the USB to boom. So USB should be deemed as its mentor. The first SATA introduced to the market is SATA 1.5Gb/s. It is the first generation SATA interface so it is officially called SATA-1. The basic transmission rate is 1.5Gbit/s.
In 2004, SATA 3Gb/s was officially launched and people naturally called it SATA-2 (SATA-II). Simply speaking, SATA 3Gb/s follows the ATA-7 specification and can transfer at 3.0Gbit/s. Obviously, the innovation of SATA connectors is constantly improving their transmission rate. After the detailed analysis, we can easily find that the advantage of SATA 3Gb / s compared to SATA 1.5Gb / s is not only by its speed improvement but actually support the real SATA command sequencing (NCQ) to expand the length of the data line to 2m which is twice as long as SATA 1.5Gb/s and of course it’s 4 times the length of the PATA data line.
The introduction of SATA 3Gb/s is not yet the ultimate idea of SATA Taiwan connector manufacturing companies. On May 26, 2009, SATA-IO completed & released the final specification of SATA 3.0, which brought SATA 6Gb/s to the market as well. It's not hard to see that SATA 6Gb/s is twice as fast as the previous generation with a number of new technologies added, including the new NCQ instructions to improve the transmission technology and reduce the power consumption required for transmission.
In fact, SATA 3.0 is reaching the ultimate in many details. For example, it achieves a state of reduced power consumption by adopting the new INCITS ATA8-ACS standard. At the same time, SATA 3.0 improves the transmission signal technology, which can reduce the power consumption during transmission.
In fact, SATA 3.0 has taken the leading position among SATA connector devices. But after that, SATA Taiwan connector manufacturing companies introduced SATA, which is a device that should be developed in matching the market direction of miniaturization. In short, the main innovations of eSATA are as follows:
1. The interface shape of eSATA is quite different from the previous one. The purpose is to prevent mis-insertion.
2. The cable of the eSATA has been extended to 2m. And it will not affect the quality of information transmission.
3. eSATA improves the plugging and unplugging reliability of the connector for durability.
4. eSATA maintains hot-swap capability, ensuring the security of eSATA and computer equipment.
5. eSATA information transfer speed is more than double the mainstream USB 2.0.
