"so where do we stand with the warranty?
I need to check some of the detailed product sheets. "
I have the same question, and I agree you should have checked and included the information!
Regarding rebuild times, this is essentially irrelevant. The problem with large drives is with recovery of the data not with time taken to do so. With the expected unrecoverable error rates of current drives you probably couldn't even read a whole 16TB disk successfully in one go, so mirroring is useless, RAID 5 is useless, and RAID 6 is probably useless. Erasure coding might help.
Reliability could be improved through internal data resilience at the cost of some drive space. Many "drive failures" are not actually drive failures at all so internal resilience could be used to recover some of the UREs.
