This is the virtual device I use for my message and files data files, makes the Search features MUCH MUCH faster. Also has a big effect on the message base Continuous Read feature. I didn't use it at first, when the software and hardware were still getting broken in, but I've been using it for about a month, now, and except for one blow-it (turned the power off, heh), I haven't lost anything. I put a little cardboard cover over the power switch to remind me, BTW. I have a Wait scriptfile in my st-seq that copies the message data files to disk every hour, and the files data files once a day. Once a week I copy the data files over to a separate backup dir, just in case something gets corrupted in the meantime. For what it's worth, no Max's file of mine has ever gotten corrupted. If for some reason I don't want to use SD0, like if I want to keep the memory free for some online rendering, I have a small Fix scriptfile that patches in a "BBS" for the "SD0" in the Paths & Opts menu for the message and files paths, so I don't have to bother manually changing each node. Spoiled? Yep.
