Me and a buddy were debating about this earlier, and neither of us are really pros in the field. I figured someone on here might know.
The debate was about weather it would be smarter (in terms of performance and cost) to buy, say, 4 250GB HDDs and set them up in striped RAID 0, or a single smaller SSD. It seems to me that the access time advantage of the SSD would pretty much override any benefit gained from the striping, but I'm not positive. Anyone have any insight?
