Is RAID in general an obsolete technology today?
This is a technology that is so commonly used, so transparent, that we really don't even think about it...
So, RAID is doing very well, it's just no longer perceived as a discrete technology. Moving forward, expect to see more awareness around RAID-6 and its importance for all types of large capacity drives. Over time, I'd expect more controller enhancements that will speed up the rebuild process and ease the need for dual parity. Ultimately, RAID is here to stay. It's an integrated functionality today. Five years from now, we'll probably be talking about virtualization and hybrid drives with the same blasé attitude.
