Kanex adapter?

[ivnj]

So good news according to facebook the thunderbolt to usb 3.0 adapter is coming soon q2 this year. Under 100 they said. And cheaper than any hub on the market. Plus I don't need a full hub anyway. Just usb basically.

Anyhow so how does this work. Thunderbolt is 10bg and usb 3 is 5gb per second. So it will just go 5gb per second? Or an adapter is not capable of ull speed? And if I get a hub can I still get 5gb each (5+5=10) or it is limited to 5gb because of the port? And then therefore it will be 5gb devided by 4 ports? Or if I'm only using 2 of the four ports 5/2 and the other 2 ports stay unused?

Just an educated guess:

- there is a single USB 5Gbps bridge chip inside, so if connected to a hub, the 5Gbps is shared amongst the various peripherals you have connected to the hub.

- this is how any built-in USB 3.0 port would act anyway

As already stated, if it only has one port then you can't somehow cram 10gb/s worth of data into a 5gb/s port. A hub would only be sharing the 5gb/s bandwidth. Most likely wouldn't be a huge issue, but it is something to think about. It's the same issue with adding a second Ethernet switch to a router (and/or the initial ethernet switch). All of the devices on the second ethernet switch are bottlenecked to the devices on the first switch by the one connection and vice versa. This is normally not a problem, but it is why the expensive switches use Fiber backplanes so that the bandwidth from switch to switch isn't a bottleneck.

I assumed I was limited to the usb port and not the other side. Or maybe I can convert the esata port to usb3.0 with some kind of adapter like the newertech one. I'm probably limited to that speed although newertech claims it can make things faster. They should of made options for online ordering only with 2 usb ports or other options incase anyone wanted one but they didn't. They wen't with the general public. So Or I can split it with a hub but I was just not sure how that worked. If it was share with all ports or only the devices I connect. Because Otherwise I only need a 2 port hub and not 4 if its wasting the bandwidth even without anything connected. And strictly 2 ports only is hard to find. If not and its like g4cube said only what I have connected is sharing the 5gb then it doesn't matter. But was not sure so I wanted to double check.

Well, if there isn't anything attached to the additional ports then you aren't "wasting" bandwidth". However, if you had two super-fast USB 3.0 devices trying to send data to your computer, they would have to split the 5gbps bandwidth.
