These have been popular for some time now and I've been wondering what are the chances of manufacturers sending better batches to Backblaze. I imagine you run some batch and some percentage of disks don't pass tests, you may adjust something or maybe it's the last one before routine machine maintenance, etc. No idea if there really even is such thing as batches which manufacturers know have higher failure rates. But it would be interesting.

Backblaze shouldn't complain though ;)
