I've noticed that very few drives today support spindle synchronization for use in a RAID array as compared to drives from 5-10 years ago. In terms of practicality and feasibility, why is this the case? Do you expect spindle synchronization to make a comeback?
Spindle synchronization is only useful for RAID 3, which has turned out to be far less useful than people thought it would be. I don't know for certain, but my guess is that the overhead of spindle synchronization probably ate most of the benefit.
