But raw flash writes on the order of 1-2 milliseconds, so the 5 microseconds must be the latency to write to a ram cache inside the stick. I wonder what the latency would be for a write larger than the buffer. For that matter, how large is the buffer?

- digikata 12y agoThe article did update with a benchmark link comparing a couple of models to a fusion io card. http://www.percona.com/blog/2014/08/12/benchmarking-exflash-with-sysbench-fileio/ http://www.percona.com/blog/2014/08/12/benchmarking-exflash-... So the 95%, write latency is 1-1.5 msec for one model, and 2.5-3.5 msec for another model. Maybe representing SLC/MLC flash? 95% read latencies are maybe 350 or 250 usec.
