As you try to understand the performance capabilities of potential new storage systems, including flash and hybrid flash, a vendor-independent methodology is essential.  All of the vendors will make their own performance claims and present benchmarks that show their products are the best.  Unfortunately, this information is not relevant to your production applications as those vendors don't know your I/O profiles.  Storage performance validation from Load DynamiX provides the vendor-independent testing platform that will empower you to keep the vendors honest. Trust, but Verify!
