USB 3.0
Hi, fellows of
Cyberspace, today I want to talk about USB 3.0 and several of its improvements,
let us start.
In view of the fact
that between 2004 and 2006 came the first external hard drives, allowing
storage on Gigabyte and Terabyte, it was clear that USB 2.0 technology, which
gave us a speed of 480 Mbit / s would soon be very slow, to This amount of
data.
Therefore, in November
of 2008 appears in the market the USB 3.0, with the main feature that is the
multiplication by 10 of the transfer speed, which happens to be of 4.8 Gbit /
s, to this new technology is called; USB 3.0 Super Speed. This is because now the
cables allow working with five lines to send and two to receive, allowing bidirectional
traffic.
It has also changed the
current, which is now 900 milliamps, reducing the charging time of mobile
devices.
These new ports have
the intelligence rule, that if devices that are connected for a while and are
inactive, they immediately go to a low power state.
At the end of 2009,
manufacturers such as Asus or Gigabyte presented the basis of the forms with
this new revision of the bus. The 3.0 version of this universal connector is 10
times faster than the previous one.
Now 3.0 ports have a
light blue color to differentiate them from 2.0 ports
Where you can see a big
change is in USB 3.0 Micro-B - The sidecar:
The only solution for
USB 3.0 had a smaller connector. It was to take the existing Micro-B connector
and stick another connector next to it. This appeared mostly on external hard
drives, as they needed more current. The popular theory is that this format
will be replaced very quickly by Type-C.
This connector is
compatible with USB 1.x and 2.x always losing the advantages of USB 3.0
