The 100 "GB" OCZ Vertex LE in my laptop has 27,834 hours of power-on time. This is the only drive in the system, and it houses several always-on encrypted swap partitions. I'd be surprised if you could purchase a new one at this time, though. :P

I can get back to you in a little more than a year about the 750 "GB" Samsung 840 EVO in the lady's laptop, and 6->8 months on the Crucial M4 SSD in my gaming PC. :)
