How to distinguish between USB data cable and SATA hard disk data cable 2.0 and 3.0

The appearance of the SATA hard disk data cable 2.0 and 3.0 cable does not show much difference. The cable produced by different data cable manufacturers may specify the cable specification on the color and cable ID. SATA hard disk data cable 2.0 or 3.0, but whether SATA2.0 cable is used between SATA3.0 hard disk and motherboard, or SATA creative data cable custom 3.0 cable is used between SATA2.0 hard disk and motherboard Can be universal, there will not be any specification compatibility issues.SATA hard disk data line 2.0 can refer to any of the extended features, that is, a product that has any of the above features or combinations can be referred to as a SATA 2.0 hard disk. Since the SATA specification was very confusing afterwards, the new SATA 2.5 specification is a continuum of the SATA 1.0a specification and the 6 SATA 2.0 extension specifications. Its introduction is only for the convenience of system vendors or hard disk manufacturers, because everyone can use a specification to replace All existing standards. In fact, for the average consumer, we can't get much useful information from names like SATA 2.0 or SATA 2.5. What we really need to care about is what features and advantages new hard drives have to determine whether it's worth it. It pays.

Compared to SATA 2.0, the SATA3.0 final specification doubles the bandwidth to 6Gb/s. The difference between SATA HDD data cable 2.0 and 3.0 is the new interface transmission standard. It is not a different interface specification. The two interfaces are compatible with each other. The main difference is the logical difference. The performance improvement depends on the hard disk itself and the mainboard. Performance to determine, theoretically improved a lot, but the actual application is generally no obvious difference between mechanical hard drives and solid state drives. In addition, SATA3.0 will also prioritize the resources that are being processed by the system, greatly improving the efficiency of the system.

        1. The “USB 2.0” is marked on the USB data line, indicating that the data line supports the USB2.0 communication protocol.

2. USB3.0 data bandwidth is ten times that of USB2.0, can reach 5Gb/s (480MB/s), synchronous transmission bandwidth can reach 384MB/s, this is one of the main differences between USB3.0 and 2.0;

3.USB2.0 provides ample bandwidth for a wide variety of devices and applications, however, USB3.0 cable manufacturers with high-definition video, TB (1000GB) class storage devices, up to gigapixel digital cameras, large capacity With the advent of mobile phones and portable media players, higher bandwidth and transmission speeds have become necessary. The transmission speed of 480Mb per second may not be fast enough, not to mention that no USB 2.0 device can reach this theoretical maximum speed limit. In practical applications, the average speed of 320Mb per second is already very good.

4. The USB data cable manufacturer 3.0 is more energy-efficient than 2.0, and can use the power-saving mode for devices that are temporarily in a waiting state.
