I agree, the longer warrantee now makes it much more likely that I would buy one of these for my home systems, as well as work systems. But it does come down to the number of writes in the specs, which I haven't touched yet.
Don't you all look at warrantee length when you buy spinning rust too? The extra money is well worth it when/if a drive dies 4 years down the road. You might argue that it will be obsolutete by then, but it probably will still be useful no matter what.
