They key aspects for Enterprise drives (both disks and SSDs) are generally 1.) Performance and 2.) When you buy them they come from seperate batches (i.e. a single failure doesn't indicate more are likely to follow).
Servers should basically be created to cope with drive failure in such a way that % of failure isn't an impact on "will this cause problems" but merely on working out the cost of using them.
