When did that guy do that study of SSDs? Basically hammered them to death 24/7? I think it took about three years of continuous write/erase cycles to destroy them.
Given that most drives are obsolete long before they've had three years of writes ... the conclusion was that - for the same write load - "modern" (as they were several years ago) SSDs would probably outlast mechanical drives for the same workload.
(Cheap SD cards, on the other hand ...)
