PE1 and USB3.0

Posted 02 February 2010 - 08:32 PM

Saw today the first external HDD with USB3.0
Does anyone know if XP/Win2k3 need new USB drivers to support USB3.0 out of the box?

Should actually be obvious. Not even Windows 7 support it currently.

So your PE will properly stick with "slow" USB 2.0 speed.

Let's hope MS provide an update for this old OS

What not even Win7 has this yet?
How can that be, M$ is listed as one of the developers of the standard?

You won't be able to test it unless you have the required hardware though so I don't know how much good its going to do you.

I do not have USB3.0 yet. But if eighter the old driver were good enough or M$ would have had already a new driver, i would have put it in NaughtyPE. Cause when the first external HDD show up, it can't be long till everyone is going USB3.0

Now only the USB-Sticks need to get that fast and USB-Bootsticks are really the way to go.

Intel have an alternative to USB 3.0 called Light Peak which is twice as fast.

I love standards , there are so many of them....

...but Light Peak is an optical technology, I presume it will be initially VERY costly:

It is very probable that the USB 3.0 - which is a "lower end" technology, expecially since existing manufacturing utilities will be able to use existing machines and technology will be embraced instantly by most manufacturers, while "Light Peak" will be - at least initially - reserved to the higher end.

Not many motherboards support USB 3.0.

There is already a whole bunch of boards with USB3.0 available, but i have not yet found any reference, if they can use this speed also during boot.
So i assume they work like USB2.0 boards and support the full speed of the bus also during boot.

Even Higher speed ????? - USB 3

I propose:

MUCH Higher speed!

http://www.usb.org/developers/docs/

But they already went for "superspeed":
http://www.usb.org/developers/ssusb


In a nutshell:
1.1=12 Mbit/s =÷MAX 1.5 Mbyte/s
2.0=480 Mbit/s=÷ MAX 60 Mbyte/s
3.0=3.2 Gbit/s=÷MAX 400 Mbyte/s up to 5 Gbit/s "RAW"
(above are "theoretical" speeds, NOT actual ones)

In practice, to image a 160 Gb disk over USB 2.0 =÷ 1.5 hours, with USB 3.0 maybe 15 minutes. (no, it won't work that fast anyway - or not so soon, as HD are not yet that fast), let's say that it will probably compare to SATA 2.0, i.e. 3 Gbit/s on the interface but limited by actual disk speed.

400MB/s Can you imagine a PE-image loading to RAM in half a second?

@Wonko
Are those 60MB/s for USB2.0 theoretical or practical. I have never measured anything faster than 30-40MB/s on my machines

Yes, I would say anything between 1/2 and 2/3 of 60 Mbyte/s is what you can normally expect.

With USB 3.0, the cutoff should be more "relevant".

A "normal" hard disk rarely goes over 150 Mbyte/s, the real news are that an OS should load at the same speed no matter if on an internal hard disk or on an externally connected device.

And of course SSD's will become everyday's matter.

Yep, those who can read, have a clear advantage!
