gig of memory, try using "mem=512M". Does this change how big the file
needs to be before
No, it's not Ubuntu specific and Canonical didn't cause it.
Right now I'm copying between two SATA drives, connected to my PC via
eSATA. So far a lousy 600MB has been copied and I'm already down to
5MB/s and falling.
Here is what I know about the problem:
It affects ALL hardware.

Hello,
this bug isn't ubuntu specific I think.
I can reproduce this problem with Debian 3.1/4.0/5.0 and linux 2.6.29 too.
Can you try it with Ubuntu 6.06 again? There doesn't affects me this problem...

backup is now at 64GB and has slowed down to 500KB/s and I will have to
stop it.
Usb is now officially a completely useless backup tool on linux.
just stopped it, dd claims 65GB has been copied avg 1.5MB/s
like to mention that this has always been a very intermittent issue.
sometimes works fine
I wil have to disagree with about ram. busy trying to clone my root
partition with dd to a usb hard drive. booted with jaunty 32bit live cd
and started the process with dd if=/dev/sda3 of=/media/disk/image.img

slowing down to 10MB
Hi Lucas,
I noticed everything goes fine until the memory gets full, then starts
the swapping and the slowdown. It's like the memory is used as buffer,
when that runs out it uses the virtual memory on the HD. No problem with
small sizes that fit the memory but when you select 100 GB at once ...

Hi Kurt,
albeit the AHCI-mode enables the use of Native Command Queueing (NCQ)
for some mainboards, I somehow doubt that this has to do with the USB
issue. Especially because of the "swapping" you reported which IMO has
nothing to do with the USB speed issues reported before.

file transfers
I had the same problem, needed to backup 200+ GB to a USB HD due to a
hardware upgrade. Then I remembered the board had a strange bios reset
recently (hence the upgrade) so I checked and set the bios SATA
configuration back from IDE to AHCI (My mobo has 3 possible settings
IDE, RAID and AHCI). Now
Same problem here, I have Thinkpad T500, starting speed was about 15
MB/s and at the end only about 3 MB/s, size of transfered file is 3,2 GB
dist: jaunty 64 bit
