USB 2.0 or USB 3.0 look for a new USB
USB 2.0 or USB 3.0 look for a new USB plug or connection in your new computer. Technology this year is once again in a boom year. We in the old American Auto industry called it a Retooling year. That's when physical and technical changes made it impossible to use old designs and a completely new design was needed. The IT Retooling.
USB 2.0 was so much faster than USB 1.0 that most of us added the investment of additional hardware when the USB 2.0 hit the market.
Today we have USB 3.0 which should make your old USB 2.0 look slow.
It's basically a redesign making it full duplex with the connected devices.
Not to worry if you don't have USB 3.0 just make sure if you are buying new peripherals that have USB 3.0 that you pick up a USB 3.0 card for your computer.
I'll list the technical differences in the technicians area when our first units come in. (We have to buy the equipment like the next person. No sponsors during tests only after we test we sell the best of the group.)
Just keep in mind if you don't have heavy need of fast data transfer to your external hard drive SATA 600 then the USB 3.0 will be one of your normal upgrades when printers and external hard drive enclosures only offer USB 3.0.
Speed quoted to us is about 10 times faster but this will once again be based on equipment that has no lag, latency or full duplex bottlenecks. Be sure to look up USB 3.0 in WikiPedia to see what's referenced if you are looking to buy something today.
What you wont see is the full test results on the side of the box. If USB 2.0 was 480Mbps transfer per second that means one direction or half duplex in a two-way communications or full duplex that speed would be cut down between 25% and 50%. Then if you test with a HUB your speed with several devices would be divided then divided by 50%. There is a formula which I'll publish soon but those numbers are only for descriptive wording to give you a better idea of what industry classifies as transfer rate and how it is measured.
But no matter how I split, divide, subtract 480Mbps (Mega Bits Per Second) is must slower than 5Gbps (1,000 Mega Bits Per Second) .
