You fail to mention which drives come good on any guarantee that writes actually make their way to permanent storage when the drive reports so. With that in mind, the minimal performance figures you quote are even more useless.
For example, the Intel 320s have a cluster of capacitors onboard that make it behave as advertised. But what about the others?
I'd also like to see a review where drives are tested to failure, so we know what they do when they fail. I.e. do they fail hard, do they have honest smart data or do they lie?
