Ranking suggestion...
Looking over the selection, it's still hard to make a choice. I'd love to see a graph which shows the size vs cost vs warrantee length. I'd be willing to pay extra for a longer warrantee, since I could amortize that expense over a longer time. Maybe Cost/GB/Year would be an interesting metric to look at?
As others have said, random read/write performance is much more interesting that sequential, and would also impact my purchasing more. But really, it's all about reliability first, since the speed is good across all of them.
Now to figure out how hard it would be to move a windows 7 install from HD to SSD without bringing along all the data. Or only some of it.
