USB and IEEE1394 relatively, evident difference is that both are different on transfer rate.In the past, a lot of people can select for use IEEE1394 to make transfer files usefulness, because fast hundred times of its throughput ratio USB1.1 versions.The transfer rate of USB has only 12Mbps/s now, can only connect low-speed devices such as keyboard, mouse and microphone, and IEEE1394A can use 400Mbap/s, can be used for connecting the equipment that digital camera, scanner and information household appliances etc. need two-forty.And afterwards, released USB2.0, though catch up with IEEE1394A to some extent, the flow of IEEE1394B, IEEE1394C can also increase to 1G.

Just, widely whether everybody uses for specification or interface, and having more than is to be that whether its function is very strong, also has all multifactor impacts its popularization.In fact, the popularity rate of IEEE1394 is exactly far away from USB, and this causes certainly will will providing the interface faster and also very universal than USB in order to satisfy the requirement of circumscribed Storage Media on transmission speed.

The SATA interface becomes the focus that various memory devices are paid close attention to recently gradually, and the SATA hard disk replaces the main flow that the PATA hard disk becomes hard-disk interface of future generation, and CD-ROM driver interface also will progressively be converted to SATA.On following Intel main flow level 965 platforms, its ICH8 has just thoroughly abandoned traditional ata interface.

In addition, in order to satisfy at a high speed and the demand of external storage device, especially from SerialATA (SATA) extend circumscribed SATA (External Serial ATA, eSATA).Briefly be exactly by the eSATA technology, allow exterior I/O interface use the SATAII function, and transmission speed external and that can provide far above USB or FireWire is provided.

Though the eSATA2 interface can reach the transfer rate of 3Gbps in theory, but in the practical application, be subjected to the restriction of hard disk Internal Transfer Rate and mainboard, actual data transfer may be between 1.5Gbps between the 3Gbps, but still is higher than the transfer rate of IEEE 1394, USB2.0.

In disk sheet or flash memory, be equipped with simple read-write state and adjust assembly, as long as the user does not wish to include data might be capped the time, only need to promote simply to adjust assembly to a read states.Yet, in above-mentioned any circumscribed interface, each have their own relative merits, but they equally lack as mechanism that can simple and easy adjustment read-write state as the flash memory.
