There is, roughly. This is a lab test as opposed to production monitoring, but it is still interesting. Obviously SSDs and HDDs are quite different technically, so the appropriate test is quite different. They write data continuously to see how long they last.
We've now written over a petabyte, and only half of the SSDs remain. Three drives failed at different points—and in different ways—before reaching the 1PB milestone[1]
After a few hundred drives, our anecdata is that failure over time on SSDs is generally related to drive endurance. Make sure you use a SMART utility which can read (and translate to English) the current net usage of the drive. Throw them away when you get to 100% usage.
I recently examined a set of Crucial m4s which were at 130% of usage. There was no lost data, but write bandwidth was hilariously bad (around 10-20MB/s).
