USB 3.0 Speedsow and later
In our laboratory, we can obtain the paces of 460 and a million byte per second. We prove this discloses it in November of 2008 on USB forums of 3.0 developers.
Around CES, I see some news probably USB 3.0 tempo ” Only ” So-and-so’s pace. It find those industries still I weather have till that time confirm tell the truth expectations of product news initial and oddity that one, we see the title like equally immediately ” In a predicament give meet expectancy or ” The sale that irst products do not say rotates, ” Than USB 2.0 fast 5 x. ” I guess sometimes people need to visit the thing wanted to write of their network diary. It is not I that do that.
I (again) It was the day of several million bits of WiFies per second in early time to like getting back to the pace, and you must buy it from all you of the same company. For example, 802.11 PCMCIA card of SMC works only with the router of SMC. The same thing is used ” Draft N ” Material. All work have, sew together now ” N” With high-speed material) .
The any standard one execution but implement standard because of. This always implements that thing. Influence performance to be a factor:
-USB controller on the apparatus implements
-Link the controller in the apparatus
-Interrupting and hiding on the bus on the apparatus
-The bus on the apparatus hides
-Firmware and driver on the apparatus are implemented
-Operating system on the apparatus
-PHY on the apparatus implements
-Quality of USB telegram
-PHY on host implements
-Operating system on host
-Pile and the driver on the host computer
-Host (for example PCI is being expressed) The bus on one’s body hides
For example, early chip group PC prevents and only has the flow of the 8 million bytes per second on the point of USB 2.0 at low price. We buy from Dell and PC that test per second to use HDBench 40 million byte at the same time. We use the same operating system and hard disk to urge, and receive very different responses from the board that is made by oneself.
In we find out a concrete example of the question in fact, it measure we by one MP3 player flow while lasting USB the only USB PHY of 4 million bytes of seconds of the 2.0 PHYs from in want spec (the we one) . The data are passed, but use and retry in a lower rate. Sure your PHY has a kind of good eyes pattern.
All points of this are that our young demonstration reveal that is diluting the system with small hardware and software, our core will not be the blockade in USB 3.0 design. If other components can make the data pass, we can make the data pass.
In addition, this was compared with and posted once and often posted even more every 3 months at that time, I made
