Hello,

I have a dual Opepteron with 1 SATA 80 gig drive and 1 IDE 160 gig
drive in it. I will set it up as a dual-boot Suse 9.2 and Windows XP
system. It will have 6 gigs of physical RAM. It will for all practical
purposes be used to run one application only, when under Linux (MATLAB)
or Windows (EMSE), to do large number crunching of 2 - 3 gigabyte data
files. The drives will be on separate controllers.

I know for maximum speed, the swap space needs to be fastest, so I want
to put swaps for both OSs on the SATA: 1 swap for Linux (12 gigs) and 1
swap for Windows (12 gigs) on first two partitions on the SATA drive
(to be near the outer edge of the disk).

I've read that the swap should be on a different drive/controller from
the disk accessed most, to avoid conflict over access.

My question is, which will be accessed most: the data, the application,
or the OS? I would think in this data-intense environment, the drive
with the data on it will be accessed far more than the application or
OS, so I would tend to put the data on the IDE drive, to avoid conflict
with the swap on the SATA disk.

But I have no idea if this is true, and have no clue at all whether the
next-most-accessed thing is the application or the OS, and whether
these should go on the SATA with the swap, or the IDE with the data.

Any info and advice would be very appreciated. Many thanks....

Jim
