Ubuntu installed on USB stick works very slow (not at USB 2.0 speed)
Posted on 2008-06-20
I have finally succeded in installing and booting Ubuntu from a usb stick (8gb). but the problem is that it runs very slowly sometimes. I believe that this is because it doesn't work at full USB 2.0 speed.
user@lenovo:~$ sudo hdparm -t /dev/sdb1
Timing buffered disk reads: 54 MB in 3.07 seconds = 17.57 MB/sec
however when I give:
user@lenovo:~$ sudo hdparm -T /dev/sdb1
Timing cached reads: 2112 MB in 2.00 seconds = 1056.50 MB/sec
Is there any way I could make it work faster than 17mb/sec in these conditions?
