This is just some PR wildly exaggerating results from a SSD garbage collection paper. The linked graphs show the big improvement in just one of many workloads and only in the case where the SSD is near-full, and don't show what disk/ftl they're comparing against. But even then these are their own hand picked benchmarks. (presumably the details will be published along with the paper at some point) The trick itself is that they scramble the LBA addresses of blocks with some 1:1 function. But it raises the question why the FTL doesn't already do this. Which is a reason to suspect they're benchmarking against some el cheapo SSD with a dumb FTL.
