Abstract: A method includes, upon a read operation for a stripe of a storage device, determining a percentage amount of potential read amplification for the read operation. A current age of the stripe in the read operation is determined as a percentage of a longest safe elapsed time between read scrub operations on a stripe of the storage device. A read scrub operation is performed on the stripe when the current age is greater than the percentage amount of potential read amplification.
