      I seem to be getting better performance with a nothing-special Western
      Digital 40GB external USB drive:

      # lsb_release -d
      Description: Debian GNU/Linux 5.0.6 (lenny)

      # cat /proc/cpuinfo
      Processor : XScale-IXP42x Family rev 1 (v5l)
      BogoMIPS : 266.24

      # dd if=/dev/sda1 of=/dev/null bs=1024 count=1000
      1000+0 records in
      1000+0 records out
      1024000 bytes (1.0 MB) copied, 0.712626 s, 1.4 MB/s

      # hdparm -t /dev/sda

      /dev/sda:
      Timing buffered disk reads: 36 MB in 3.08 seconds = 11.69 MB/sec
