So I decided to experiment with attaching a USB2.0 hard drive (Maxtor OneTouch) to the system (SIIG PCI controller). I use a OneTouch on my Windows/XP sytem and it works really well. I wanted to explore placing my mailstore on an external USB2.0 drive - would be easy to port the data to another system if I needed. However, in experimenting with replicating some data (via rsync), I'm wondering if this is a bad idea. While rsyncing data over the wire to the USB2.0 drive (mirroring some data, basically), the shell response to something like "ls" would hang (eventually completed, but much later). I wonder if someone can advise about the use of this drive for that purpose (mailstore) and if there may be some tunables I would need to tweak to get better performance. Thanks.
