To extend on your comment: It's not possible to predict individual drive failure with reasonable accuracy. It's disconcerting to see the parent comment suggesting this still sits at the top of the thread.
You can roughly predict the longest possible lifespan for a SSD under a given workload. Regardless, a significant percentage of drives will still die earlier than that.
I'm only saying this from experience developing storage systems that are yet unreleased. You can predict the lifespan of the SSD in the storage system if you give up many of the functions of the SSD controller and put them in software RAID.
If you're talking about most incredibly naive SSD storage systems available today (excluding violin memory and maybe xtreme/pure), then I agree with you.
