Yup. I believe the VS2000 uses 2:1, bit it might be 3:1. I'm
fairly certain that it's not 1:1.
That said, though, I've never actually benchmarked a RQDX3-
formatted drive against a VS2000-formatted drive plugged into an
RQDX3. I'm assuming the bottleneck will be the rotational latency
(and thus would be affected by interleaving) but there may be a
tighter bottleneck elsewhere.
