Endurance really isn't an issue, most of my 14 TB+, and growing, might as well be etched in stone. And yes, M-Disc has always been on my really would love to have list. Any problems that I forsee here revolve around pri e point and that SSD's fail completely with no warning. Still. That's why NAS disks feature here.
So, Tosh-WD, what's those gonna be?
