I have just uploaded a new release of the online VDI Flash Calculator.
This is a Major release and include cool new features. Despite a number a requests I have delayed including IOPs calculation due to the workload specific nature. I wanted to make sure that aspects such as Read/Write ratio and RAID penalty were properly included in the calculations. Read my article Get hold of VDI IOPs, Read/Write Ratios and Storage Tiering to understand the implications.
