    A 5:1 dedup ratio might work for some data, perhaps even VDI, but it’s utterly implausible for others or if users encrypt their own data (which is increasingly common in the kinds of environments Pure targets). Also, higher dedup ratios come at the cost of more CPU+memory to detect similarity on the way in, and to do correct refcounting for parallel access etc. on the way out. At the I/O rates that are possible with lots of flash drives, this can just move the bottleneck from the storage to the controllers. IMO they’ve spent a lot of time addressing non-issues, but their claims remain unproven (not necessarily false) wrt the real issues.
