I first want to say thank you for your in-depth single user vs. multi-user RAID analysis. It is very clear why RAID0 has little benefit for the single user. I was wondering if you have done any analysis on the actual performance gains of multiple non-raid disk configurations in desktops? For instance, placing the swap or pagefile on a separate physical drive from the system and/or putting the data being frequently accessed on yet another drive. Multi-user servers (especially database servers) gain a lot from reading/writing simultaneously to separate spindles / disk arrays. So my question is: does the same hold true for the single user scenario under heavy load? Under low memory conditions? Working with lots of monstrously large files that canâ€™t fit into RAM? This would seem to be a better approach to leveraging multiple hard drives in the same desktop. Would you agree?
