It's been a week since I swapped my WD10EADS-00M2B0 for a replacement WD10EADS-00M2B0. It's been running in my Duo as Drive 1. The drive has 124 power-on hours. The Load Cycle Count continues to grow, with just over 3000 park/unpark cycles.
My other drive (Drive 2) is a WD10EADS-00L5B1. It has just over 1200 power-on hours, and a mere 780 Load cycles.
Let's do the math.
The older -00L5B1 with firmware 01.01A01 has .65 load cycles per hour of operation.
The newer -00M2B0 with firmware 01.00A01 has 24.2 load cycles per hour.
It's clear the two different variants behave differently.
