So, to paraphase this, if with these various I/O tests and tools it is determined that disks are suffering from latency issues, adding RAM or an L2ARC will help, and there is really no drawback of doing one or the other as both will be used as available. So, it's just a question of to what extent to feed the seemingly insatiable beast until it is satiated?
Would it be safe to say that given the price of RAM and its performance that it would be best to start with adding RAM until it is maxed out or close to being maxed out, particularly if you have the RAM slots (as I do)? Is it also accurate to say that this is all relevant to read speeds and not write speeds? Still, by improving read speeds you'd provide ceiling room for the drives, and in doing so increase write speeds as well.
