Whilst on the subject of storage, this is just obscene.
Four Intel X25-E SSD’s in RAID 0. Those are the SLC variants too, which are still ridiculously expensive (Currently $447 for a 32GB one).

So $2k for an average read speed of ~560MB/s is impressive, though a little out of my (and most peoples) price range.

I still haven’t got to the bottom of why RAID0 of my two cheap MLC SSDs didn’t yield any noticable improvements at all.
No matter what I tried, I was bound to the performance of a single disk (~80MB/s).
