The slow usb-storage performance is still valid in Kubuntu 9.10
(linux-image-2.6.31-14-generic).
It was important for me to format my SDHC card (16 GB Class 10!) with a non
journaling filesystem.

I tested again using Kubuntu Hardy updated to the 2.6.27-rc3 kernel
mentioned above.
A 300GB Caviar SE PATA drive attached using a USB-IDE bridge cable gave
the following transfer speeds when copying files using Dolphin:
Async: 20MB/s
Sync: 2.4MB/s
There was a lot more head activity in sync mode
Hi pato101,
If testing via a LiveCD won't be sufficient, you can enable the Intrepid
repository to grab the newer kernel.

Where can I get these linux-image-2.6.27-* packages?
as for 2), I commented that, strangely, at the liveCD this issue did
not happen (couldn't test the DVD-RAM issue but the usb-stick one
yes).

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the
upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would
appreciate it if you could please test this newer 2.6.27 Ubuntu kernel.
There are one of two ways you should be able to test:

This is still a problem under Kubuntu Feisty.
An external USB 2.0 hard disk formatted with Ext3 writes at about 600KB/s with
the sync option enabled.
Remounting the drive async gives around 20MB/s write speed.

Please note that same happens with ext2 filesystem that supports
"sync" and "async", but not with reiserfs. The problem was first
detected on usb pendrives, where "sync" is an interesting option to be
used whereas it is not at DVD-RAM.

Confirmed (on Breezy).
When "man mount" tells us that "sync" isn't even a valid option for udf
filesystems, I wonder why this has an effect.

I'm afraid they problem persists.
However, I've been told that it does not happen with the LiveCD. I
cannot check the liveCD with the dvdram, as I have only a single
drive, but the liveCD behaves OK with the usb-stick while the
installed version does not.

Do these performance issues persist with Ubuntu 6.06 LTS?
