Mike,
you didn't say how important speed is to you, and how large your wallet
is. If the answer to both is "very", you can think about getting 1 HD +
1 SSD (solid state disk). A decent SSD costs 3 times as much as a small
HD but will be more than twice as fast, hence faster than any RAID made
from 2 HDs, at least while reading. Reading probably matters to you most
since you talk about the boot drive. Writing speed on a decent SSD is
about as high as on a single HD.
A SSD is presumably the best (fastest) method to boot from. I assume
they qualify as flash drives. On the other hand, USB flash drives cannot
be particularly fast, unless you have USB 3.0 (hardly the case for your
computer, since it runs on a 250GB IDE HD). USB 2.0 limits the speed to
about 34MB per second, less than half the speed of a cheap HD.
