Re: Trunas scale exp?

Thanks for all the info.  Will be really looking into the CMR / SMR disks.
  For my disks I am running 9 small SSD drives.   Might be worth buying 32g
memory.

As a side note I erased my first build and went with default install on new
hardware with pcie 3.0.  Seems to have made a big difference.
