Everything You Need To Know About USB 3.0
Esther Schindler writes "After a lengthy gestation period, the third generation of the Universal Serial Bus is making its way to the market. USB 3.0, also known as SuperSpeed USB, has throughput of up to 5 gigabits per second. That's even faster than the 3Gb/sec of SATA hard drives and 1Gb/sec of high-end networking in the home. USB 3.0: Everything You Need to Know goes into plenty of the techie details. But is it already obsolete — will LightPeak make USB 3.0 irrelevant?"
So, each USB iteration offers the smallest possible increments in speed?
One detail missing from the article was the relative costs of the two technologies, with the popularity of net books and the like the cheaper technology will probably come out ahead in the long run.

SATA is up to 6.0 Gb/s now, and networking is starting to hit 10Gb/s.
I never see my hard disk data rate maxing out my connection speed, so I con't understand why all this emphasis on faster connections.
Have you ever heard of SSDs?
Fuck the blind!
Home network, let me introduce you to your new friend USB 3.0. He is really fast, so I expect the rest of you to keep up! Don't be the bottleneck and you get to stay right where you are instead of being tossed in the bin.

The only reason I can see would be if you had an external USB enclosure that housed multiple drives that you plan on RAIDing. With the speeds of SSD drives still ramping up, it is possible you could saturate even USB 3 with just 2 drives.
Finally? I hope all the companies that implemented that horrible plug will go back to mini-usb. It is as big, by far more robust, you can get cables for it and you are not afraid to plug it in. And plugging in is easier, as the plug will "find" its way in.
You can get a micro-USB cable at any halfway decent camera store. It is not that much more fragile than Mini-USB. They both "find" their way in; I find that most micro-USB connectors are more recessed into the plastic (possibly by specification?) and thus cheap connector edges are less likely to hang up, which IS a real problem (if an exceedingly minor one) with Mini-USB that you don't tend to see with any other variant.
There has never been a worse plug than micro-usb.
Clearly you don't remember PS/2 ports, even though you probably have some in your house. Actually any Mini-DIN is shit. I also have a certain hatred in my heart for RJs, I think they are shit. They are cheap though, so at least THEY have a purpose. The Mini-DIN is just a gigantic failure of imagination.
"You're right," Fisheye says. "I should have set it on 'whip' or 'chop.'"
This is why they should just use bandwidth numbers. I never understood why they started language unrelated to the specifications.
The one major eSATA issue(I don't know why they overlooked this the first time) is power. For 3.5inch drives, or multi drive external towers/shelves, this doesn't matter at all. An external PSU is a given. For the "single 2.5 inch or smaller in portable case" case, the fact that USB3 delivers the bandwidth(and is backwards compatible right back to the two-1.1-ports stuff that they were shipping in the mid 90s) and the power, while eSATA delivers only the bandwidth, requiring a seperate connector for power, pretty much ruins things. If eSATA had included power from the start, it might have been a much better contender.
As a replacement for SCSI type use cases, of course, USB is a toy and eSATA or SAS is the natural replacement; but for the vast market for flash drives, 2.5 inch externals, and mass-market, works-with-anything 3.5 inch externals, eSATA is doomed compared to USB(especially since a USB port can be used for non storage purposes, while an eSATA port is pretty much storage only. In principle, a high speed serial interconnect like SATA could be used for other stuff; but I've never seen it actually done in practice.
Yes, of course: It will be as irrelevant as USB2.0 was as soon as FireWire was introduced...
Ohwait...
Before USB
RS232 - Open standard
SCSI - Standard - No Pins
PCI - Standard
IEEE 1284/Parallel - Standard
FireWire - When available - Standard - No Pins
Where were all these non-standard proprietary connectors ...?
And is it just me or are many of these still around because USB2 does not replace them ...and USB 3 won't either ?

Reminds me of SCSI, Fast SCSI, Fast-Wide SCSI, Ultra SCSI, Ultra-Wide-Fast SCSI, etc
Because the marketing people say that numbers are scary.
I read the internet for the articles.
This is also why monitors come in nice and easily memorable names like WSXGA+ and WQXGA (not to be confused with QWXGA) instead of something scary or potentially useful like 1680x1050.
