With the hard disk capacity of larger,the entire recovery process becomes longer.So it should increase the frequency. Supposed the speed of recovery is 100MB/s(i think for HDD is good). The total time of recovery 4TB hdd is about 666 minutes.So change the frequency from 16 to 64 times,it's about 10mins.
