      I guess the point is, the configuration is entirely circumstantial. If I was serving web pages all day and not storing tons of micro data, then faster reads would be useful.

      it is purely a theoretical case where reads are not useful. There are pure read systems, there are mixed use, there are write heavy systems but there really aren't any real world use cases for a pure write system. You are always reading the data sometime.

        Any experience with LSI fastpath using SSD arrays as cache on the front end for a larger array of SAS spinning drives on the back end? LSI says its super fast, but that is their job to tell me that. I have been debating implementing one server like this to see how it goes.

          Windows software solution, AFAIK it's dead now that virtualization has taken over. It was some bizarre and foolish approach using software to control the hardware. Bad idea.

          The CacheCade approach was much more sound.

            Thats what I thought too. So if I wanted to make a major upgrade to these servers it would be better for me to use the SSD I already have for cachecade RAID1, then buy 4 2.5" 6Gb/s 15K 300Gb drives for a RAID5. That sound right?

              Very likely. But we aware that CacheCade is read only acceleration. It works great, but only helps writes by getting reads out of the way.

                @scottalanmiller Ah yes. I forgot that its a "hot data" caching system. I dont know if that is particularly useful for me.

                  Intel has started calling Blind Swap - "Surprise Hot Plug".

                      No idea. But it is decently clear.

                        Because you're surprised when you blindly swap the right drives?

                          The system is surprised, to say the least.
