At the Windows Hardware Engineering Conference (WinHEC) 2008, USB-IF President, Jeff Ravencraft revealed that the new specifications for USB 3.0 would be fully released on November 17 at the SuperSpeed USB Developers Conference in San Jose. The USB 3.0 architecture is also named SuperSpeed USB due to its incredible 5 gigabit per second (Gbps) data transfer speed.

“Delays have held USB 3.0 back,” said Lars Giusti of Microsoft. However, he predicts that the fully signed-off USB 3.0 specifications would only be presented to the implementers in the USB 3.0 Promoter Groups in 2009. Subsequently, it would take approximately another year until broad-scale product deployment of host controllers, devices, and systems utilizing USB 3.0 would be available in the market. President and general manager of the chipset business unit at AMD, Phil Eisler, released a statement saying, "The future of computing and consumer devices is increasingly visual and bandwidth intensive. Lifestyles filled with HD media and digital audio demand quick and universal data transfer. USB 3.0 is an answer to the future bandwidth need of the PC platform.”
“Our early indications tell us that most partners think that we should support USB 3.0 on at least Windows Vista.” According to early information supplied by Microsoft the improvement in transferring large files using USB 3.0 based hardware will be considerable. Performance comparison: Transfer of 25GB HD movie: USB 1.1: 9.3 hours USB 2.0: 13.9 minutes USB 3.0: 70 seconds (Source: Microsoft/WinHEC 2008)

if windows got usb 3.0, the speed will be too faster to let hard disk down. our hard disk speed not faster than usb 3.0, how could widows work with it? do we need to update our system to raid 0? |
|||
|
|||
|
I think that widows will do just fine, they have already gone through lots of stress and sadness losing their husbands, so i think they will be able to handle this. |

Nice comment sauce, that was funny as hell. I almost spit out my coffee once I realized what you were referring to. |

Dude we just did the math. How can USB 3.0 transfer 25GB at 70sec with a Transfer rate of 600MB/s? (25 gigabytes) / (70 seconds) = 365.714286 MBps. I'm I missing something here? |
|||
|
|||
|
Tito - quick answer - yes you are missing something - 600MB/s is the theoretical max limit 365MB/s was demonstrated by MS in real life. |
|||
|
|||
| Minus one for misutilizing the English language. | |||
|
|||
|
This is already inferior to FW400, and certainly FW800. It\'s obsolete. |
|||
|
|||
|
USB 2.0 max speed limit is 480 Mbit/s = 60mb per sec USB 3.0 max speed 4.8 Gbit/s = 600mb per sec = 42gigabites in 70 seconds When your computer is fast enough for it! |
|||
|
|||
|
Yeah sure, it\'s slower than FW but how much of computers have FW? uhm, 10-20%? |
|||
|
|||
|
Umm Al and Al2, you might want to have another look at Firewire.. it's only 400Mbit and 800Mbit. USB 3 is ~4800Mbit.. |
|||
|
|||
|
No, USB 3.0 has a max rate of 600MBs. It's average speed, like all USB, is significantly lower - it looks slower than FW400 which is constant 400, while FW800 is constant 800. IT'll cost you $10 to put them in . YOu want real speed? Try HDMI and DVI. The fact they aren't standard with everything is just idiocy. |
|||
|
|||
|
Oh, and I haven't bought a computer w/o firewire in a loooooooong time. I've bought about ten in the last two years for home and work. |
|||
|
|||

USB1.1 = 12 Mbps FW400 = 400 Mbps USB2 = 480 Mbps FW800 = 800 Mbps SCSI160 = 1280 Mbps SATA1 = 1500 Mbps SCSI320 = 2560 Mbps SATA2 = 3000 Mbps USB3 = 4800 Mbps HDMI1.2 = 4950 Mbps SATA3 = 6000 Mbps HDMI1.3 = 10200 Mbps |

Does anyone know when it is going to be released?? Can't wait... xDDDD |
|||
|
|||
| Thanks for the speed table bspds. | |||

i think usb 3.0 will be useful but we already have HDMI and eSATA, makes it kind of redundant i think, isn\'t this more a battle of one company\'s tech VS another to get themselves more money. i dont think usb 3.0 is really needed. |
|||
|
|||
|
The one advantage USB 3.0 may have over eSATA is the length of the cable. eSATA is limited to 2m, while USB 3.0 is supposed to be 5m max. |
|||
|
|||
|
Firewire is great, but USB is more popular. Over 6 billion USB connector sets have been sold. As long as USB is going to be prevalent, it's a very good thing that the performance is getting better. |

Anyway someone thought about mass storage speed ? Or removable media speed ? ... they're a lot below actual (HDMI 1.2/1.3 or lastest SCSI...)transfer buses even with SSD coupled in raid0 the only use offered is uncompressed HD video and audio from a playing device to a TV... I don't know if even next generation platforms will have real use for this |
|||
|
|||
|
hey bspds, I think SCSI and SATA are not plug-n-play device. whey should we compare with other standards? |

Will the next generation of Apple Macbooks have USB 3.0 built-in as soon as USB 3.0 is released? |

Most of the comments are trying to compare specifications of different products. It’s like comparing a lorry to a train. Sure both can carry things but in different ways and with different limitations, one of which is power… USB 2.0 = 5V, 500mA (2.5W) Firewire (IEEE 1394a and b)= 30v, 2A eSATA 2 = N/A USB 3.0 = 5V, 900mA (4.5W) FireWire 3200 = Not sure, simliar to 1394B? eSATA 3.0 = 6000Mbps (notes cases) and rumoured power output as well. Although firewire 3200 is slower than USB 3.0, it has the advantage of power. If eSATA gets a decent power output (say 30W+) it will be the future – depending of course on physical distance limitations. USB 3.0 has one major advantage over all other though: Cost. As Al pointed out you can add a firewire card to your PC for little money, but what about the peripherals that use it. I can’t think of many *CONSUMER* devices that support firewire 800. Why? poor memory perhaps, or just too expensive to make and not enough support for it. |

i want to know the perfect dimensions of the USB layout...means height and width of USB3.0 when it is drawn with layout designers |

You may want to look up info in MegaBits and MegaBytes. There are 8 bits in a byte. FW800 is actually 800Mbits. So divide 800 by 8 and you get 100MB (MB is MegaBytes). Therefore FW800 has a transfer rate of 100MB as compared to USB 3.0's 600MB. |
