We asked Western Digital a similar question several months ago,
namely, would it improve performance to install 2 separate armatures
with pivot points at opposite corners of the 3.5" rectangular form factor?
They replied that those moving parts are extremely complex,
and doubling their number would only double the probability
of a failure.
Functionally speaking, RAID 0 works the same if 2 x 3.5" form factors
are used; likewise, RAID 0 works the same if 2 x 2.5" form factors
are used.
If you are trying to conserve space, then a really neat
solution is the QuadraPack Q14 from Enhance Tech:

This is a 4-in-1 enclosure that accommodates 4 x 2.5" lap top HDDs
in a single 5.25" drive bay. We bought one last December,
and the Q14 is very well engineered -- highly recommended.
I'm looking forward to reviews of 4 x 2.5" VelociRaptors (no IcePak)
installed in a Q14 (or similar 4-in-1 enclosure) and configured as RAID 0.
The enterprise VelociRaptor also comes in a 150GB model,
in addition to the 300GB model. Hopefully, the 150GB model
withOUT the IcePak cooler, will be less expensive overall:

I've asked Newegg to stock both enterprise models.
