Timing cached reads: 1194 MB in 2.00 seconds = 597.27 MB/sec
Timing buffered disk reads: 104 MB in 3.02 seconds = 34.40 MB/sec
The results were +- 15 MB/sec for cached read throughput, and +- .3
MB/sec for buffered disk reads over several iterations.
A quick bonnie++ test (using the -r 250 -s 500 flags as I only have 1.2
GB of disk free and 1.5 GB of RAM)

Anadtech was really happy with the performance of the Intel SSDs.

It was the price per GB that I was focused on. For me at least, there
needs to be a lot more movement of the cost before it becomes
compelling, especially in light of the disagreement out there about the
actual power savings.
Hope this is useful,
