I'll have to second this. If you try this drive on a 33M bus, and it's
the only device on the bus, you're not likely to see any improvement
just by sticking it on a 66M bus. The drive is the limiting factor
here. I don't think there's a single-disk system that does much above
20M or so.
In other words, you won't see the advantage of 66M bus, over the 33M,
unless you stick something like a RAID on it, or transfer only from
the devices cache.
