My guess would be that it accumulated all that write usage back before you put it into this RAID1. If you want to ensure the RAID1 usage is even, record the SMART data you have now, and compare to the readings you will have a month later.
Hmmm, oops, I should have looked at that. Now of course, I realise one drive was replaced under warranty when it failed around 6 months ago (well, the value says just under 9 months actually), and that would explain the difference in wear and power on hours (aside from the initial full sync when the new device was first installed).
So, 2.5 years old, and 74% life remaining, and 9 months with 93% life remaining.
Sounds good to me, I should expect these to last at least the 5 years I was hoping for, and probably before that happens I will want to upgrade them to increase capacity anyway.
