Assuming you're talking about rebuilding a RAID and not the independent disk: Depends on load, number of parity drives, numbers of drives in the array, reliability of the drives and risk tolerance.

still.. rebuilding 40 tbs would be like 3-4 days.
I mean for my 8 tb drive it takes 12 -16 hours and its a 8 drive array.

RAID rebuild time is dependent on actual consumed space, and system hardware.

My QNAP, rebuilding a 4 drive RAID 5, takes about 1.5 hours per TB consumed space.
