Simple question about parity drive failure.

Featured Replies

new user here and sorry about the lame question, can't seem to find the answer or just not asking the correct thing in google.

what happens if the parity drive fails?
will the array work as normal and just not be protected until a new drive is rebuilt as parity? Or will it be in a protected state with lower performance?

coming from using a drobo where from what I understand everything was spread out over all the array where in unraid it is just stored on the parity drive.

ok thanks, what I thought but I could not for the life of me find verification. in general terms is there a time to TB it takes to rebuild the parity drive?

  • Community Expert

It can vary a lot depending on the hardware used, but generally about 2 to 3 Hours per TB.

Just to elaborate on this a bit. In unRAID, parity is stored on the parity drive, and each data drive has its own separate files. Unlike traditional RAID, each data disk is independent. https://lime-technology.com/wiki/index.php/UnRAID_6/Overview#Parity-Protected_Array

You would notice a sudden surge in write speed. :)
