Hi all, I have a 2.5in usb HD and 2 external usb2 cases. I've been getting pretty average performance with a 7200 rpm drive in both cases, but I just thought this was the way it is.
However, I just did a test: $ time cp /usr/portage/distfiles/OOo_2.0.1_LinuxIntel_install.tar.gz /mnt/usb-storage/device-0/partition-5/ real 1m20.903s which is pretty slow. I copied the same file in winblows (without changing usb ports or anything) and it copies in about 15 seconds. I noticed I had uhci-hcd loaded (the usb 1 module?) so I unloaded it, and my keyboard stopped working!!! So using the laptop keyboard, I replugged the HD (now without uhci-hcd) and it still goes slow... $ sudo hdparm -tT /dev/sdd /dev/sdd: Timing cached reads: 3640 MB in 2.00 seconds = 1820.28 MB/sec Timing buffered disk reads: 30 MB in 3.13 seconds = 9.60 MB/sec 9.6 is pretty slow! I should be able to get at least double that... And as I've said, I know this port is usb 2.0.
