Hi all, |
| 2 |
|

I have a 2.5in usb HD and 2 external usb2 cases. I've been getting |
| 4 |
pretty average performance with a 7200 rpm drive in both cases, but I |
| 5 |
just thought this was the way it is. |
| 6 |
|
| 7 |
However, I just did a test: |
| 8 |
$ time |
| 9 |
cp /usr/portage/distfiles/OOo_2.0.1_LinuxIntel_install.tar.gz /mnt/usb-storage/device-0/partition-5/ |
| 10 |
|
| 11 |
real 1m20.903s |
| 12 |
|
| 13 |
which is pretty slow. I copied the same file in winblows (without |
| 14 |
changing usb ports or anything) and it copies in about 15 seconds. |
| 15 |
|
| 16 |
I noticed I had uhci-hcd loaded (the usb 1 module?) so I unloaded it, |
| 17 |
and my keyboard stopped working!!! So using the laptop keyboard, I |
| 18 |
replugged the HD (now without uhci-hcd) and it still goes slow... |
| 19 |
|
| 20 |
$ sudo hdparm -tT /dev/sdd |
| 21 |
|
| 22 |
/dev/sdd: |
| 23 |
Timing cached reads: 3640 MB in 2.00 seconds = 1820.28 MB/sec |
| 24 |
Timing buffered disk reads: 30 MB in 3.13 seconds = 9.60 MB/sec |
| 25 |
|
| 26 |
9.6 is pretty slow! I should be able to get at least double that... |
| 27 |
|
| 28 |
And as I've said, I know this port is usb 2.0. |
| 29 |
|

Any hints? |
| 31 |
thanks, |
| 32 |

IN MY OPINION anyone interested in improving himself should not rule out |
| 36 |
becoming pure energy. |
