  • Everything beyond two drives is for capacity expansion. As long as all of your data will fit on a single drive, you can turn on share duplication for all your shares and the files in them will be protected against the failure of any single drive.

  • Yes, you will get a Network Health notification pop-up, when you run into a shortage of space. WHS keeps about 20GB free on each disk, so your .5tb disk will actually use .480tb - the same with all other drives.

    I would go with a third drive, unless power-saving is a requirement.

    As an aside, most of the WHS's I have set up, have been with three drives from the start. That way, very little data is stored on the C:/D: system drive and all saved user data etc is across the other two drives.

  • Thanks Ken,

     

    I installed a second 1tb drive.  The system drive is a .5tb drive.  Will WHS notify me when it can no longer mirror data due to the drive size mismatch?

  • Thanks,

     

    I understand that when the system drive is down to 20mb free I will be notified that I am out of disk space.  Would I then be better off to install a second 1tb drive for a total of 3 drives, or replace the system drive with a 1tb drive?
