I have 2 external USB disk drives, one is 1.5TB the other 1TB. Copies to and from the external disks to the local disk, or between the 2 external disks, take a long time and while the copy is going on the system is essentially unusable, e.g.. it can take 15 to 30 seconds for virtual desktops to update. Moving the mouse is very jerky, the mouse stops for 5 to 10 seconds then moves then stops again. I run netbeans IDE with the netbeans projects on one of the external drives. Even when I'm not doing anything with the IDE the disk light on my laptop will go on solid for several minutes leading to slow response times. I'm running on a 2Ghz Core 2 Duo processor with 2Gb memory. What I notice during the copies is that both CPUs are 75 - 90% in wait state. I'm also running an encrypted root file system. The problem is really bad when I try running VMware Workstation 7. The virtual machines are all located on one of the external disks. When I run one VM the system response time on the system degrades significantly as noted above and I have to shutdown the VM if I want to get anything done.
