I am interested in the 8890 for high end scientific
code development and scientific computing. One
thing that appeals to me is the capability of having
3 hard drives with two of them setup as a Raid 0
array. To me, the way this would really make sense
is to be able to set up the primary hard drive and
the TV tuner bay hard drive as a Raid 0 array. Also,
it would then be great if it was possible to boot up
from the modular bay 2 hard drive. If this were
possible, then one could presumably have different
operating systems installed on different hard drives
and you just insert the one you want to boot up.
It is my current understanding that neither of these
two options is possible with the 8890. Instead, the
design of the motherboard constrains the Raid 0 to
use the primary hard drive and the modular bay 2
hard drive which means that you can't really remove
the modular bay 2 hard drive if you are using Raid 0.
It is also my understanding that it is not possible to
boot from the modular bay 2 hard drive but I don't
really understand why. I plan to be running both
Windows XP and Linux on my laptop and will primarily be using Linux.
Does anyone know if there is any way around these
limitations so that I could accomplish these two
objectives? For instance, would it be possible to
somehow swap leads on the hard drives so that the
motherboard thought that the hard drive in the TV
tuner bay was in the modular bay 2 and vice versa?
I guess if it were possible to do the lead swapping
trick, I would need to be able to boot off of a hard
drive that the system thought was in the TV tuner
bay. Is that possible? It is my understanding that
it is not convenient to swap hard drives in the TV
tuner bay whereas it would be trivial for modular
bay 2.
The reason I want to use the Raid 0 setup is two fold.
First, when I do C++ compiles of my source code, it
takes a long time and does alot of disk IO. I'm
hoping that faster hard drive performance would
speed up my compiles alot. Second, some of the
data files produced by my code take along time to
write and benefit from having a fast file system. So,
I don't really want to give that up.
Also, are there any rumors about when 80 GByte
7200 rpm hard drives will become available? I can
really use all the fast disk space I can get.
Thanks,
Dave
