"Backblaze Hard Drive Stats for 2020"
https://www.backblaze.com/blog/backb...tats-for-2020/

"In 2020, Backblaze added 39,792 hard drives and as of December 31, 2020
we had 165,530 drives under management. Of that number, there were 3,000
boot drives and 162,530 data drives. We will discuss the boot drives
later in this report, but first we’ll focus on the hard drive failure
rates for the data drive models in operation in our data centers as of
the end of December. In addition, we’ll welcome back Western Digital to
the farm and get a look at our nascent 16TB and 18TB drives. Along the
way, we’ll share observations and insights on the data presented and as
always, we look forward to you doing the same in the comments."

At 2 drives failing out of the 60 Seagate 18 TB drives, I am not sure
that is an anomaly, but it does look bad.
