Hardware, Embedded Systems This is an article which discusses the increase in storage capacity while performance and hard error rates have not improved significantly in years, and what this means for protecting data in large storage systems. "The concept of parity-based RAID (levels 3, 5 and 6) is now pretty old in technological terms, and the technology's limitations will become pretty clear in the not-too-distant future " and are probably obvious to some users already. In my opinion, RAID-6 is a reliability Band Aid for RAID-5, and going from one parity drive to two is simply delaying the inevitable."

There is a large amount of consumer grade SSD's which might work well for those who do not expect high throughput I/O and a long life cycle. When you start paying $20,000.00 and upward for a storage array, everything changes.

I am sure I am not the only one who thinks that SSD's are not ready and waiting for early adopters and risk takers in the field to shake them out before recommending them as part of a replacement or upgrade solution for existing storage.
