You've already received a few responses about reconfiguring your entire
server, so I'll avoid that route and simply answer your question straight.

"No"

There will not be a "significant" performance boost striping only 2 drives.
 The 10K RPM Raptors alone will definitely increase performance, but there
is little/no real advantage striping them together.  Getting any
significant performance increase from a RAID array really requires at
*least* 4 drives ... the more the merrier ... although I'll probably catch
some flack from that statement. :-)

A previous poster mentioned increasing your RAM from 1Gb to 2Gb.  That was
an excellent idea and should be done in parallel with whatever drive
changes you make.

Ken
