I agree that SSD boosts performance... In some rare not-real-life scenario: - super frequent commits That's it, nothing more except the fact that Lucene compile time including tests takes up to two minutes on MacBook with SSD, or forty-fifty minutes on Windows with HDD. Of course, with non-empty maven repository in both scenario, to be fair.
another scenario: imagine google file system is powered by SSD instead of cheapest HDD... HAHAHA!!! Can we expect response time 0.1 milliseconds instead of 30-50? And final question... Will SSD improve performance of fuzzy search? Range queries? Etc I just want to say that SSD is faster than HDD but it doesn't mean anything... -Fuad Sent from my iPad On 2012-01-19, at 9:40 AM, "Peter Velikin" <pe...@velobit.com> wrote: > All, > > Point taken: my message should have been written more succinctly and just > stuck to the facts.
