I think that the data of IDF and internal variables are moved to
the RAM space from HDD space when you are running the EPlus simulation. So the
running time will be a matter between the CPU and RAM, not HDD I think.
Of course, if you have extremely fast storage device, like SSD
or RAID HDD, the generation of output files will be faster than
slow devices. However, this phase is only the last step of
simulation, so it will now affect so much on the overall runtime.

Hi,
When running EnergyPlus on a laptop how
much does hard drive speed affect execution time?
Thanks,
Karen
