I work on a large distributed database system. SSDs absolutely have correlated failures. Also CMOS batteries. Also CPU and memory (think a manufacturing defect or a storage climate issue on specific batches that made it through QA). Pretty much nothing is 100% guaranteed to have no correlated failures. It comes down to probabilities. You can add flexibility, variation, vendor/sourcing diversity to reduce risks.

Went through a rather large batch of OCZ SSDs that all failed within a two week window years ago. Thankfully the IBM Death Star had long before made me allergic to putting devices of the same model in the same RAID array if I can help it, so it was a nuisance rather than a disaster.
