...and now for something completely different.
I dunno. Blowing a lot of money on something outlandish just doesn't seem that interesting. On the other hand, it is pretty trivial to max out the more common tech. All it takes is a single spindle really. What would be more interesting is seeing how easy it would be to "take it up a notch". How accessable is another level of performance above and beyond what's cheap and readily available.
There seems to be a big gap here and the interesting story I think is how you could make that gap smaller. My own SSD-free setup could probably benefit greatly from such an incremental improvement.
