From the article and throughout the comments here it seems Backblaze prefers cheaper drives over a few percentage points of reliability. It would be interesting to see some data showing the tradeoff, but I suspect it reveals too much of their operation. At first glance it appears you can get a drive with .9% failure rate (HGST 7K3000) for $127[1], and yet BB really likes the WD Red, which has a higher failure rate (3.2%) and cost[2].
What might shed light without revealing too much is information about where they source drives today (their sourcing coverage during the shortage was very cool!). I suspect they're finding some nice bulk discounts somewhere.
