For drives that are meant to be Enterprise Class, the lifetime should be long enough for almost any application.

The 400 GB drive on this link is rated a 35 PB of lifetime writes, so that would mean you could write 1 TB of data on it each day for 98 years, or 20 TB per day for 5 years.

They are expensive though. I saw the price listed on one site at around $5,700.
