Truth is, I couldn't be bothered to look further than the datasheet of that last generation drive. I don't have one in my possession, so I couldn't speak from experience. I see now one test here http://www.techreport.com/articles.x/13440
showing a 105 MB/s sustained data rate on a Barracuda 7200.11 .
So performance is still not the big winner with SSD, and as you kindly point out, neither is price per GB. I still believe that power consumption is the bigger win here - and I'm looking at it from the business user's point of view. Given, for instance, one intercontinental flight and the choice between lugging a laptop with a SSD and an extra battery or a normal laptop and 5 spares, which one would you choose?
