hosting Virtual Box HDD Images: SSD or HDD

[mka]

Hi, I'm hosting some Virtual Box machines on FreeNAS - exactly 21 Windows and Linux Clients. In Virtual Box there is an option to tell the guest OS the VDI Image is a HDD or SDD. The Guest OS can then disable some HDD optimizations and stuff like that.

I was wondering what setting is more appropriate when the VDI file is hosted on a FreeNAS NFS or CIFS share? Since the pool is made of HDDs but ZFSs warmed up advanced changing mechanisms behave a lot more than a SSD.

Does this option have an effect when hosted on FreeNAS?

9.2.1.8 64bit with Xeon Quadcore, 64 GiB ECC Ram, 240 GB L2ARC, 60 GB ZIL, RaidZ2 6x WD Red 6TB.

Not a clue.. that's definitely a question for Virtualbox support structure. :P
