USB interface move hard disk is the mainstream of products, the biggest advantage is easy to use, support hot swaps and plug and play, the Windows Me / 2000 / XP do not need to install the driver can work normally. According to the different standards, USB interface is divided into 1.1, 2.0 and 3.0 standard, is the biggest difference between them transfer rate of the different USB1.1 interface, the transmission speed USB2.0 interface only 12 Mbps, transmission speeds of up to 480 Mbps, and USB3.0 interface transmission speed up as high as five Gbps. Because USB standard decentralization, so at present all the motherboard the USB interface can support 1.1 and 2.0 standard, but 3.0 standard only the latest on the main board to provide. Although the price is higher than standard hard drive USB3.0 box of 2.0 standard to your 50 yuan, but its performance improvement is a qualitative (when large data transmission, 2.0 standard interface that long waiting just really upset), so please try to purchase USB3.0 interface move hard disk, even if your main board box, also can not support for future leaves room for the upgrade.
IEEE1394 commonly known as "the", the interface of the data transfer rate in theory can be up to 400 Mbps. But because IEEE1394 interface is not popular, equipped with a piece of the price does not poor need special IEEE1394 interface card can work, so the price is higher and the computer not to general, between popularity.
And ESATA interface hard drive, but generally used for box 3.5 inch hard disk box, the speed can reach 1.5 Gbps SATA standard) or (3 Gbps (SATAII standard), general now is new on the main board have ESATA interface, or could also buy a SATA turn ESATA connecting card, the price also is ten to dollars. In popularity, and USB2.0 USB3.0 before and can't meet the requirements of data transmission, ESATA interface hard disk box is certainly a good choice, other than the price also only ten dollars USB2.0 your just.
Introduction: USB3.0As Vsita operating system, high definition video and DX10 gradually popularizing of large capacity, high speed, the data transmission is more and more, the demand for bandwidth more and more is also high, the original USB1.1 and USB2.0 has failed to meet the needs of the future. By the end of 2007, Intel company and started hewlett-packard (HP), NEC, NXP and Texas Instruments (Texas Instruments) company to develop USB3.0 technology, USB3.0 technology is used mainly in the personal computer, consumption and mobile products rapid synchronous instant transmission.
USB 3.0 is backward compatibility standards, USB1.1 and USB2.0 standard, compatible with traditional USB technology usability and plug and play function. USB3.0 technology goal is 10 times faster than USB2.0 out more products, use with cable USB the same architecture. In addition to USB 3.0 specification order to achieve lower power consumption and higher efficiency of the agreement, USB 3.0 port outside and cable can realize backwards compatible, and support the future optical fiber transmission.
USB3.0 will adopt a new physical layer, among them, with two channel the data transmission (transmission) and confirm (acknowledgement) process, thus achieving the separation of high speed. In order to replace the current USB the take turns detection (polling) and radio (be sensed) mechanism, the new specifications will use the packet routing (packet routing) technology, and-only allow terminal equipment have data to send only for transmission. The new link standards will also make every component support DuoZhong data flow, and each data flow can maintain independent priority (one priority levels), this function can be in video transmission process used to terminate the interference caused by shaking. Streams of data transmission mechanism also make inherent instructions queue (native command queuing) possible, thus can make hard disk data transmission optimization.In order to decentralization version 2.0, USB 3.0 adopted 9 design, and four of them over the pins and USB 2.0 and the shapes of the same definition, and another are 5 root is special for USB 3.0 ready.USB3.0 data transmission is 10 times faster than USB2.0!!!
