Page 2 of the article repeats the end of page one.

Looking forward to mainstream adoption of USB3.

I'll buy it when they make flash drives that are fast enough to need it.

Fixed - thanks.

ill wait till they bring out card readers that have this built in and more devices out there have usb 3.0

I hope the next iphone uses USB3! Don't jinx it bit-tech.

Interesting results though, 5x is certainly very nice for now, but i doubt we will see USB3's true colours shine until it is incorporated into chipsets, the same goes for SATA 6Gbps

Looks like it has potential :)

Also "USB 2 can only deliver a maximum of 100mA"? Fairly sure its 500mA, we've seen several USB devices in our workshop that have a constant current draw of 400mA+.

All of the graphs say "Speed (MB/sec)". Only the graphs on the first page should.

Why on earth does the Sharkoon card require additional molex power?

[USRF]Obiwan 18th December 2009, 10:23

I wonder if there are any USB3.0 HDD enclosures available

Paradigm Shifter 18th December 2009, 10:26

So, from the sound of it, the Universal Serial Bus now has an even greater number of data lanes... wouldn't that make it the Universal Parallel Bus? :|

Overall, looks pretty promising.

Found some more!

the power draw does seem an error tthought it was 500mA for USB 2 and 1A or more for USB3

yep, sorry gang, my mistake. USB 2.0 is 500mA, USB 3 is 900mA.

Seems like more and more devices are using PCIe lanes for data transfer. With Intel's S1156 chips on P55 boards there is potential to cut into your GPU performance if too many lanes are dedicated to peripherals. Might make for an interesting article to see if this impact could be determined.

wiak 18th December 2009, 13:49

Please test the Asus USB3/SATA 6Gbps board on a AMD 790FX chipset, why? well the 790FX has 42 dedicated PCIe 2.0 lanes to northbridge, so basicly its PCie 2.0 all the way, unlike many intel boards

and it would also be nice to know how the Asus addon PCIe board perform on amd platform compared to the intel platform

all the test about USB3 and SATA 6Gbps has been tested on Intel platforms!

USB2 is 480mbps = 60MBps

Quote:

Additional notes from Alex Esquenet - our engineer friend based in Belgium: "A fast usb host can achieve 40 MBytes/sec. The theorical 60 MB/sec cannot be achieved, because of the margin taken between the sof's (125 us), so if a packet cannot take place before the sof, the packet will be rescheduled after the next sof. On top of that, all the USB transactions are handled by software on the PC. For instance, a USB host on a PCI bus will send or receive the data via the PCI bus; the stack will prepare the next data in memory and receive interrupt from the host."

Maybe a similar happening with usb3? The fastest I've ever seen on usb2 is a gnats under 30MBps.

dout next iphone will use usb3. Apple hasnt exactly used firewire yet which has been out forever. Even up to recently usb1 was still the only true support for the ipod series.

HourBeforeDawn 18th December 2009, 19:39

Im slowly checking off my list of when to upgrade/build a new rig, so far dx11 is checked off, usb 3.0 once its standard on mobos will be soon to be checked off, and umm ya a few more to go ^_^

Not true... The early iPod devices were Firewire 400, including my iPod 2nd Generation 10GB model. Only after USB 2.0 was a standard did they switch over to it. USB 3 for the iPod series is a definite possibility, assuming they can fit the new controller inside the ever-decreasing sized players.

+1.

I cant wait to see how much better USB 3 gets and if it will overtake SATA 6gbps. doubt it but still.

The addon cards don't seam to be too expensive, and you can never have too many USB port on a computer

leexgx 19th December 2009, 21:50

to bad that you did not test 2 devices at the same time (2 USB 3 hdds or SSDs) to see how it feared, be nice to know how usb 3 disk to usb 3 disk over an USB would of been

javaman 20th December 2009, 01:09

How is charging things using USB 3? I remember comming and plugging in my phone or camera to download/upload stuff and leaving it in to be charged up abit. Other than a quick top up I found it useless tho. It never fully charged devices and it took longer than a normal socket.
