The currently published work was from 2011, and had benchmarks for what we could afford at the time, including the enterprise-grade SATA-connected NAND. It's being compared against swap, not against the consumer-grade stuff. All of those comparisons are like vs like. If you want it summarized, look at logical slide #21 in the slide deck. It shows the gains of the same device using our approach vs swap.
The approach actually generates _less_ random write traffic than using it as swap.
It also uses DRAM for hot pages, so it's not that every application write is being
written back to the NAND-flash.
The details are in the paper - http://ssdalloc.cs.princeton.edu/technology.html
