I agree, tools may tell you file transfer speed, identify bottlenecks or some tests may show up other performance metrics, but no tool is going to show you which hard disk are going to fail. a much better idea is to plan out your storage with a sensible RAID and backup system so that a drive going down won't matter as much. If you think about it, you can only really see a pattern of failing drives after a lengthy amount of time, say for arguments sake, 6 months. so you know what drives are failing a lot, it doesn't help you at all because who takes metrics of stable solid drives? and even if you could work off the data available, are you going to purchase 6 month old drives?
Drives will be dropped, be subjected to bad power, will have firmware issues, fail for "no" reason etc... extremely hard to plan for.
It looks like you actually want to test drives yourself. Are you going to buy a heap of new ones and test? seems an expensive way to go for not a lot of garauntee.
