For ideas, I would check out Tom's Hardware for sure to see what they have compared and benchmarked in the past.

I would throw a standard hard drive in the mix there just for comparison. I also like when sites include "high performance" versions of the other technologies. (WD Raptor for example).
With SSD's, it is all about those access times and potential high read/write speeds. I don't think people realize the vast difference between SSD'd out there and how they are not all the same. You might also consider mentioning SLC and MLC drives and some of the technical differences generally found between SSD's. There is also some focus on power savings, but see what Tom's Hardware found out.
I also like the way they do price per watt and price/performance comparisons to help determine what is the best for your money.
