    That depends on what the person who has the $600 thinks.
He says he wants to use RAID 0 because his data is already
protected well enough by backup; that's his call, not mine.
This sort of suggests that the data is read-only or read-
mostly, in which case hardware RAID may not give much of a
performance boost -- but he didn't explicitly say this was
the case.

    In fact, he didn't ask about what kind of RAID to use at
all!  He asked whether he'd get better performance out of
four small disks or two large disks, and I replied that (under
a reasonable set of assumptions, which he'd need to check
against his own reality) four spindles would probably be
faster, without reference to RAID level or implementation.

    True, but he wasn't asking about reliability: He was
asking about performance.  As a storage expert of my
acquaintance likes to say, "The three things you want in
a storage system are high reliability, high performance,
and low cost: choose any two."
