Where to put stuff for best performance

Now that's a toughie.... The 7K80 is a fair age so it isn't the quickest out there (the spec sheet say 60-25Mb/s but that'll be optimistic) so it's a tough call to guess if a RAID 0 pair would be faster than the AAKS. Conventional logic says it should be slightly faster but there won't be a lot in it. If you looks at current benchmarks RAID0 gives you about a 70-80% improvement over a single drive of the same type so with the 7K80s you're looking in the 90-100Mb/s range whereas an AAKS can shift 85-90Mb/s. When it gets that close you need to start looking at other factors - is there a benefit in having 3 independant drives rather than the two that having a RAID array gives you? The answer to that is dependant on your workload although I suppose there are probablky only a few situations where you need to access three separate sets of data - I'm looking at separating my photos, the Lightroom databases and the swap file for example but that's hardly mainstream.
I'm going to be controversial and suggest that the OS, games and programs should go on the AAKS because it'll have a better random access time and that the 7K80s are used for the swap file and any other gash storage requirements you might have.

I use Virtual Machines for my work and the hard drive is a real bottleneck, so RAID is important when I can get it. According to Stewart the Hitachi's are faster but the AAKS has better random access times (How is that possible).
I'm leaning on using the Hitachi's for my OS, programs (and games?) drive and the AAKS for the swap file, virtual machines and a lot of other junk which just wouldn't fit on my Hirachi's. I plan on installing Vista 64bit soon and just wanted some clarification.
