So... Is overprovisioning still needed today? Or can you just forget about it?
Overprovisioning is the same as locking a section of free space so it can't be written on. You don't "need" overprovisioning as long as you don't fill the drive up. Try to leave min 8% of the total formatted volume in free space.
Example Formula (simplified):
0.08 x Formatted Volume = 8% of Formatted Volume.
Formatted Volume - 8% of Formatted Volume = Usable Space.
Apply to Formula:
0.08 x 500GB = 40GB.
500GB - 40GB = 460GB Usable Space.Edited by BradleyW - 2/5/16 at 7:44am
