I have two comments: 1. This article appears to completely ignore write speeds for SSDs, which aren't that good. Do people just not care? 2. I believe that while Google's server farm machine have drives, the goal is to RAM cache absolutely everything they have to serve. To the speed and power requirements of their HDDs are transient issues at worst.

The write-speed issue, even on the cheap SSD drives, is going away this year. On the RAM side, have you considered the impact of having 32 GB RAM and 640 GB SSD perform better than 64 GB RAM and 2 TB HDD ? That's what Young is pointing at.
