I tried a USB2 Maxtor One touch II external hard disk on a couple of my
Centos 4.2 boxes and found it initiallised the SCSI subsystem ok and
added device "sda". But the performance is miserable, yet the same
hardware running XP the performance is satisfactory.

<br>
HDPARM gives results varying from 120k/sec to , at its peak 4.75M/s on
a USB 2 machine, still very poor by any stretch.
<br>
<br>
On a twin CPU USB 1 machine it give a steady 1M/sec, which is
consistently slow, which is better than erratically slow ( :-) )
<br>
<br>
Still dog slow, wondered if anyone has seen this, and wondered if the
firewire interface would be better? (I need to get a cable to try
this).

I back up weekly to a Maxtor OneTouch (original) USB2-connected hard
drive. This happens while I sleep but it looks like last Wednesday
morning, it took 36 minutes to to copy 19GB.

Looks like that averages out to about
8.8MB/sec
<br>
I'm running an Athlon 2600+, 2GHz, 512MB on an ASUS A7N8X.
<br>
I hope this helps.

No, not at all. What's the setup?
<br>
How is the USB configured?
<br>
How's the drive configured, formatted ext3, vfat...
