Silly State Disk
SSD is the latest marketing initiative from all storage vendors. The reality is that SSD economics don't stack up yet. Until we have SSD that is comparable in capacity and lifespan to current drive technology, and at an acceptable price premium, only a small number of customers will see benefits from using them.
The biggest push is from the conventional array vendors that are spindle bound for performance. Virtualised arrays use disk more efficiently and don't need to rush into SSD to improve figures. It is currently far better and cheaper to throw hundreds of conventional disks into an array than sell a kidney for fewer low-capacity SSD's. Dogbert would be pleased.
