About a year ago, I wrote about the ever-decreasing role of spinning disks in highly transactional OLTP storage workloads. Back then, Texas Memory Systems had just released test results for its RamSan-630 SSD storage product that achieved more than 400,000 SPC-1 I/Os per second (IOPS) at a cost of $1.05 per I/O -- a truly remarkable performance result that was (and is) impossible to achieve with traditional disks at the same price.
