Can Blender make use of a scratch disc?

Use of a separate SSD as scratch disc in photoshop is new information to me. Can Blender also make use of such a setup?

A solid answer depends on what you specifically mean by "scratch disk".

If you mean using an SSD for some of the stuff that would normally be kept in a memory cache and discarded when the cache limit is reached, I'm not sure.

If you mean "Can I move my Blender temporary folders to an SSD", then yes.

Just go to File > User Preferences > File and set new paths on the SSD for things like "Temp" and "Render Output".

  • $\begingroup$ Thank you for your prompt reply. Yes I mean stuff that would normally be kept in a memory cache. On the latter, would I notice any performance increase by changing the temp and render output paths to a seperate SSD? $\endgroup$ – Kevin Thomas Nov 25 '17 at 4:43
  • $\begingroup$ Unfortunately, I wasn't able to look up a way to do that. However, if you haven't already, check whether you have room to increase the Memory Cache Limit setting under File > User Preferences > System > Sequencer / Clip Editor. I'm not sure how the default for that is calculated and it could be too conservative. $\endgroup$ – ssokolow Nov 25 '17 at 4:47
