Just got a samsung 850 EVO SSD (250gb, about 550MBPS read/write). Only have sata 3gb slots on my motherboard, so max is about 300MBPS. I have a Velociraptor now, wondering how much faster it's going to be. From the looks of things, the sustained read speeds are only going to be about 100MBPS better at best, though from the looks of things the "everything else related to drive performance" is worlds better.

I may put it in tonight, will let you know.
