Good New and Bad News for USB 3.0

The good news

New technology is very exciting. But in the end mean? Do you still use the old USB hardware? How will the new USB technology affect your everyday life? What are the benefits?

• Compatibility
  USB 3.0 is backward compatible with USB 2.0. So, whether you get a new USB 3.0 device or a new computer support USB 3.0, your old equipment will be able to with the new interface. Of course, this will be the old USB 2.0 speed. However, you can not use the USB 3.0 cable to connect USB 2.0 devices.


• Transfer rate
  Now, I bet all this multi-gigabit per second, megabytes and sound impressive, but it actually translate to? Well, let me give you an example. With USB 3.0 from your computer has 10 GB of files to an external drive, in about 25 seconds. Using USB 2.0 it will take more than five minutes.


• Advantages
  The USB 3.0 device will benefit most are those who have outspeed USB 2.0 interfaces, including HD cameras, Blu-ray drive, or some external hard drive.


• Supported Operating Systems
  In Windows Vista, Windows 7, and Linux has support for USB 3.0. Mac is expected to follow. Given their age, Windows XP may not receive updates to support the new interface.

Bad news

I would like to report that there is no bad news, but it is not. For example, the bad news is the smallest.

• Cable
  Maximum cable length USB 3.0 support reduced to about three meters, as opposed to five meters in USB 2.0. However, the use of hubs, the maximum length can be extended to 18 meters.


• Speed limit
  Of course, not all devices will be able to increase the speed of USB 3.0 use. Magnetic hard disk drive, for example, is limited by their RPM and corresponding read / write speed. Therefore, USB 3.0 will not start full of beauty, until the computer is equipped with every default, faster hardware, such as solid-state hard drive. But we all know how quickly progress in the IT world. Give it a year or two, you will be able to fully benefit from USB 3.0 to.
