when a save my computer on my new external hard disk with usb 3.0, it's the
same speed as when i used my old external hard disk with usb 2.0 (~1.9 gb/)
my new external disk is "Western Digital My Book usb 3.0 1 To"
I think I must instal a driver,but i dont know how to do that...
Is there any way to save with usb 3.0 speed???
(ps: sorry for my bad english, I'm swiss...)
1.9GB per second or 1.9GB per minute? Assuming it's "per minute," that's 114GB
per hour - or a little over 6.5 hours to back up the 750GB hard drive on my
new machine (coming in the mail). And this assumes the backup process checks
the entire disk for data. Is 1.9GB per minute a typical USB2 speed? What
should the USB3 speed be?
To be honest, I could live with a 6.5 hour backup time since I only do monthly
"whole system" backups. However, faster is always better (grin) and my new
system will have USB3.
sorry i forget tt say it :)
that's 1.9 gb/min with usb 3.0 :(
and i make a mistake in the title :/
how edit the title ?
FWIW, I just went to Amazon.com and noticed that one caddy they sold came with
driver software that only supported USB2. So even though your computer might
support USB3, the caddy might only support USB2. Or, it could be the other way
around, too. Do your computer AND caddy have USB3 drivers installed?
BTW, your English is fine. ;)
"BTW, your English is fine. ;)"
thank you :)
and for the driver:
i instal the usb 3.0 driver only on window, but i think i must instal the
driver on the live-cd to...
and my hard disk support the usb 3.0...
and what's the caddy?
can you give me a synonym ?
The "caddy" is the device that you put the external hard drive into. A lot of
external hard drives come with a caddy enclosure already in place. If that's
the kind of external drive you have, check with the manufacturer to see if
they have a USB3 driver for it.
i think that's an usb 3 caddy because that's write on the Cardboard box tht's
this external hard disk in compatible with
usb 3.0... But how to check if there's an usb 3.0 on window???
do you know how to see the speed ( xGB/min) on window ?
Click Here to see an example of a hard drive caddy meant
to hold laptop (2.5") hard drives. It uses USB3. Basically, you buy the laptop
hard drive separately and insert it into the caddy (enclosure). Then, you plug
the caddy into your computer. Assuming both the caddy and computer have USB3
drivers installed, USB3 speeds should be accessible.
You wrote, "But how to check if there's an usb 3.0 on window?"
Depends on what version of Windows you're running. If you're running XP,
here's how to find out:
Click on the START button.
Choose CONTROL PANEL.
Double-click on the SYSTEM icon.
Click on the HARDWARE tab.
Click on the DEVICE MANAGER button. Among the list of things, usually at the very bottom of the list, is UNIVERSAL SERIAL BUS CONTROLLERS.
Click on the "plus sign" next to that listing to expand the list of controllers. If you don't see an entry that says:
USB3 Enhanced Host Controller
but o see an entry that says:
USB2 Enhanced Host Controller
it means your computer needs to have a USB3 driver installed.
thank you, i check and i have an 3.0 conexion
I check the flow too with a special program and i have an "usb 3.0
conexion"flow on window, but not in redo...
Given that your drive works it likely works as USB3. Mist XHCI controllers do
not provide EHCI compatibility interface.
You did not say what type of controller you have so it's hard to know.
Of course, you could check if Ubuntu supports your particular XHCI controller.
There is no guarantee that whatever the speed of the controller your drive
will be faster than USB2 or the caddy chipset allows transfers from the drive
faster than USB2. You can test with some drive speed testing tool.
Finally the image is compressed so it can be saved only as fast as your
computer can compress it which is likely what is the limit here.
Can a ReDo user request that the image "not" be compressed? Assuming the
source and target hard drives are the same size, compression wouldn't seem to
be necessary and would only slow up the process. Basically, I'm looking for a
clone-style backup ... allowing me (if I wanted) to swap the source drive with
the target drive in my computer and boot up with it.
Thank everybody ,I resolve my problem!!!
The problem was that window install the false driver for my external hard
I found the good driver on the site of the constructor,and now I have a good
