(Speed using DoC vs. HD, and other tips)
Mine seems pretty speedy. I'm trying to figure out if maximum disk compression slows it down noticibly, but I didn't really pay too much attention at "standard" compression. Obviously, better compression takes more CPU time, but I think the access speed of the DoC makes up for it.
A couple other observations:
You can probably disable virtual memory completely. With 64M of RAM, you don't need virtual memory for web browsing with Opera. At least, I haven't had an "out of memory" error yet, and I often run Opera, Windows Explorer, and maybe a few other utilities while I'm setting stuff up.
You can also disable all disk caching, since the only purpose of disk caching is to put frequently used (or expected to be used) data from a slow HD into fast RAM. The DoC is fast enough already. (This also increases free memory slightly.)
You shouldn't ever need to defrag the DoC. Like disk caching, the only purpose of defragging is to help a slow HD read file data all in one pass instead of making the drive heads hop all over the drive looking for the pieces of a fragmented file. Since the DoC is just memory, one memory address is as fast as another. (I am assuming this is the case with the DoC.) Also, if you read the specs on m-sys, they say the chip may automatically move data around for "wear leveling", so that would defeat defragging anyway.
