I just read a blog where Chuck Hollis (http://chucksblog.typepad.com/chucks_blog/2008/07/
Chuck tries to paint a vision where SSD's make manually managing all the details a requirement. A wave of the future. But that's a productivity killing tsunami. Nobody can afford all of that time! Virtualized arrays have been handling multiple drive speeds for years. We'll do just fine with SSD's. The issue Chuck's trying to hide is that EMC's CX architecture doesn't include storage virtualization. They've got an inherent limiter that's going to be very hard to overcome. We "spindle randomizers" aren't going to be the ones that have to live with the consequences of our architecture. It's Chuck and company. Good luck guys!
