Don't you just hate it when people give so many details of their
computer setup, the types of drive, how they are connected, etc?

it is transferring at 12mb/s

So you have :
Â*______Â*Â*Â*Â* USBÂ* __Â* USBÂ* ______
|Drive1|-----|PC|-----|Drive2|

yes...is there any other way ? ....

And are doing a naive physical file copy rather than some sort of smart
backup software with compression?

yes that is why I was asking if there was another quicker way od doing
it.......

You would be better off with one drive inside the PC on a properly fast
SATA interface. USB3 drives can muster a fair bit of speed but if the
drive is stuck on a USB2 port then it will be throttled back.

oh well just thought it was a good idea to have a back up back up with
everything on it about 150gb.....

Sounds like it is on USB2 and the controller isn't the greatest. It
could also be that the new drive doesn't have the optimum format for
fastest possible operation. I see that a lot with USB drives.

oh right...

You often cannot obtain their published speed with the backwards
compatible format that they are typically shipped with.

Fast solid state 256GB USB thumbnail drives are now cheap enough to use
for backups on a grandfather, father, son basis.


thanks for the help ....
