[opensuse] Repeated: Copy speed (USB / openSUSE 10.1)
yesterday evening I copied some files from my USB 2.0 MP3 Player (Arcjos AV380) to the desktop.
Unfortunately, I was quiet surprised by the speed I got of this action.
a hdparm -t /dev/sdc showed it would copy at 1MB / sec (which is about USB 1.1), while I'm quiet sure I was using the USB 2.0 ports of the computer (tried different ports, and the board only HAS 2.0 ports.
Is there anything I missed in tweaking / loading USB 2.0 support? ok, I admit, the mainboard (Asus P5LD2 Deluxe) I have already gave me some surprises when installing Linux (I wanted to activate RAID0 over two discs, as the board should support RAID, but the installer detected a software raid).
Thanks for some advises, Dominique

about 1MB/sec is still good numbers ;) Look at this #114024
You can try use async mode if it will be better. $: mount -o remount,async /dev/sdc do not forget to call sync after this !!!!!!!!!!! Becasue syncing data is main problem with speed of data transfare. $: sync -- Pavel Nemec package-maintainer http://en.opensuse.org/Czech_Packagers_Team --------------------------------------------------------------------- SuSE CR, s.r.o. e-mail: pnemec@suse.cz Lihovarska 1060/12 tel:+420 2 9654 2373 190 00 Praha 9 fax:+420 2 9654 2374 Ceska republika http://www.suse.cz

As far as I can see from the specs of this board, it has an Intel ICH7R controller, which should be hardware RAID. This means the RAID is set up in the BIOS, not in the system. So configure your RAID0 in the BIOS, then the OS will see a single drive --------------------------------------------------------------------- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
