That's running the LSI Megaraid SCSI controller. Those are solid but not
the best performers in their class, particularly on writes. But given
your application description (1GB data in a year and read-heavy) that card
running a 4-spindle RAID10 should be overkill.

Current Intel chips benchmark better, occasionally you'll find people who
claim the better multi-CPU memory model in the Opteron systems give them
better performance at high loads but that's difficult to quantify.
There's not a huge difference in any case. You're probably going to
bottleneck on either disk or how fast DDR2 memory goes anyway and both
sets of products are competative right now.
