Re: Building a fast pc (1)

i would benchmark software raid0 also, hardware raid uses the
processor of the raid adapter. how fast can that be? if you use
software RAID then you will be using the processor of your system that
is a whole lot faster than the raid adapter's so if you have some
cycles to spare on your processor just go with software RAID, it is
readily available in windows 2000 and 2003, and NT for that matter.

check the RPM of both, if you get 36 then you can probably get a
faster RPM drive with less money than the 73GB. if both are the same
speed then your stripping will allow faster writes and reads, in my
opinion, if you use 36GB drives, since each disk is only writting 1/4
of the data as opposed to 1/2 of the data, and all are writting at the
same time.
