Depending on your RAM, you may want to disable swap during your sessions. Fortunately, it's trivial to do: swapoff -a Turning it back on is equally trivial: swapon -a No, you don't need to reboot. [M$ and Apple have people a bit brainwashed in that regard.] > Ideally, when recording to drive 1 the OS would use the swap partition > on drive 2 and vice versa. It won't work that way. Linux will try to "evenly" use all swap devices so as to maximise potential swap-in/swap-out performance. It cannot possibly know that you're "intending to write large files" onto one of the drives, and thereby "avoid using it for awhile". Remember that YOU (and to a lesser extent) the application are best placed to KNOW what's going where and when things are going to happen. I suggest you do one of the following: 1) Disable swap on the drive onto which you're spooling the session data. You can easily select which swap to turn on/tuff with swapoff/swapon on the command line. Type "man swapon" 2) Turn off swap altogether. If you have 300MB of RAM or more, you shouldn't need it to run your system. Remember, any extraneous activity can potentially cause xruns or additional latency. It's best to consider your DAW like an appliance during your recording work: focus it to perform just the audio recording tasks, and it won't disappoint you. If you try to make it a singing+dancing paperclip, server, chat system, and BitTorrent downloader, you may find you start to have some occasional "burps" and spikes in latency.
