Kinda scary...

Indeed smile.gif here are some benchmarks of my stuff I have

It also depends on the drive speed. When I first tested my HyperX usb stick, I couldn't get higher speeds than 100MB/s... (Advertised was twice as fast) --> Then I realized my HDD just couldn't reach that speed tongue.gif So I copy/paste the file to SSD first and then I copied it to usb stick. Now it went for full speed wink.gif (and gets pretty darn hot as well when flashing my stick tongue.gif) --> see speeds above

read above wink.gif


I recently have bought a 500GB drive for my father's laptop. The WD 500GB 3.0SS It has the same usb-connector on the PC side, but uses a different type of connector on the device side (kinda like SATA... a power side and a data side)

That article linked in the OP is not the one we should be looking at. This one http://www.businesswire.com/news/home/20130106005027/en/SuperSpeed-USB-USB-3.0-Performance-Double-Capabilities is the real article.

What the USBpromoter group has done is plan a revision to USB 3.0 to make it faster. Currently, USB 3.0's theoretical data rate is 5.0 gigabits per second. They are proposing to double that. This is very much like USB 3.1 instead of 3.0 anymore. Also, 3.0 has been marketed as SuperSpeed since its release.They should REALLY call this 3.1 instead of "next gen 3.0" or "The New USB 3.0." rolleyes.gif

There isn't a single device out there that I've personally witnessed that can hit the 5gbps mark over USB 3.0. Remember that our fastest consumer-oriented SATA ports are 6gbps and that's considered "more than enuff" for SSD's. If we could actually get crap working at that rate instead of everyone using a cheap controller, things would be awesome and there'd be no need for a new revision of 3.0

I put a 2nd gen SSD in an external enclosure w/ USB 3.

When it's plugged into a USB 2 port, it gets about 30MBps max.
When it's plugged into a USB 3 port, it gets over 100MBps, which is comparable to its speed over SATA II.

Been running two 4-bay boxes through USB 3.0 for almost a year now. The R/W speed are maxed out. It is nothing like the old laggy days of USB 2.0 slow transfers.

I'm really excited to hear more about this.

So will this be a software update?, or will this be a hardware update?

hope it's software...one of the main reasons I got ivy bridge chipset over sandy bridge was native usb3 support.

idk about guys getting such low speeds on usb3, im getting anywhere from 50-110 mbps transfer rates, it usually stays somewhere around 80 or 90 mbps for 1 large file transfer

That's because you are likely capped by your HDD's speed anyway. Unless you are using an SSD you will be capped at a mechanical drive's read/write speeds even on USB 2.0 in most cases.

Which is why when my buddy who is an Apple guy started getting excited about thunderbolt drives I just shook my head and laughed. Theoretical bandwidth is only good if something is saturated and the component can make use of more throughput.

This will have no significance, other than electronics such as cameras and MP3 players. I don't know of any camera's or mp3 players with USB 3.0 though :/
