more than two volumes – real-world benefits?

Anyone finds real-world benefits in creating 3 or 4 different volumes, especially on a laptop?  I see a lot of suggestions on this forum to do exactly that, even on laptops (really?), and find it puzzling.


One thing is shaving seconds off PPBM benchmarks. It’s like drag car racing – sure, add that 0.01 psi of pressure, it may help at a slightly higher risk of engine blowing up.  Top fuel cars are rarely practical on a grocery trip though – or on an autocross or oval track.


It’s a totally different thing when you tweak the hell out of your system – all for the benfit of saving what, 1 second in 8-hour editing day?  It’s money better spent elsewhere, not to mention that multiple volumes also mean multiple points of potential failure.


I usually create two volumes total:

– (1) OS / boot / apps, and

– (2) media, which also hosts projects, media cache and all other media-related things.


If (and only if) the client does a lot of faster-than-realtime encoding and exporting, or in some other rather extreme circumstances, there may be another dedicated volume for encoding / exporting output.  Then there may be additional volumes, storage devices for backup and archiving, a whole different topic.


What I am looking for is editing professionals trying both configurations (3-4-tier and 2-tier), and vouching for one or the other, with real-world benefits.  This assumes of course that the editing system is not choking on memory or other things and is otherwise balanced.


Put it another way: outside of people who do a lot of faster-than-realtime encoding, what are the benefits of more than two volumes for editing in Pr?
