I have been using UNRAID for a little over 18 months. My issue with not with using the usb keys but the inability to replace more than one a year if failure occurs. I use Sandisk Ultra 3.0 and have had 3 of them die completely since I started using UNRAID. One was due to a motherboard failure that took the drive with it, but the other 2 just quit working. Not recognized on any system, just dead!! My key backs up every night, data/config loss is not my concern, I just have a Server down until I can get this sorted out with LimeTech. Feel like we are being penalized because of hardware failures we cannot control.
I had a new drive created and restored in 5 min, system back up in 10, but I cannot start the array until I get the licensing key issue resolved, sent emails to support. Now all I can do is wait . . . . . . . . .
