re: Flash Dependent Storage Systems Take Off In 2012
I think we agree with each other. I am not saying that Flash will never replace disk. It will definitely, without a doubt replace disk as the price continues to come down and capacities increase. The technology is across the board superior to disk. I am just not sure that 2012 will be the year (as the title states) when Flash dependent systems take off and start replacing disk arrays in substantial numbers. It is like tape vs. disk. Disk is way better than tape all around and has largely replaced tape for everything other than archiving and back-up, but it didn't happen overnight. I think you will see Flash integrated with disk systems, which already exists, and then as the Flash technology matures people will ditch disk altogether.
BI will be the first to go all Flash as the software already supports it and the data volumes (a couple of hundred GB) are relatively small. For the 10s of TB RDB workloads and hundreds or even PB unstructured workloads, it will probably take a few years at least.
