Does SSD affect the simulation speed?
 

Hi everybody,

Does anyone investigated the effect of replacing a HDD with a SSD on simulation speed for example in fluent?

Depends if your simulation is i/o-bound or not. E.g. for transient simulations that write a lot of data while computing the solution, fast storage definitely helps.

I found it help most with post processing of large transient simulations. For example, making transient charts with a lot of time steps can take a very long time, and SSDs help a lot with that. During the solve usually there is not a big difference unless you have a situation like Alex describes, but that is usually rare, and the post processing will take much more time if you are writing that many results anyways.
