Default "Backblaze Drive Stats for Q1 2021"

"Backblaze Drive Stats for Q1 2021"
https://www.backblaze.com/blog/backb...stats-q1-2021/

"As of March 31, 2021, Backblaze had 175,443 drives spread across four
data centers on two continents. Of that number, there were 3,187 boot
drives and 172,256 data drives. The boot drives consisted of 1,669 hard
drives and 1,518 SSDs. This report will review the quarterly and
lifetime failure rates for our data drives, and we’ll compare the
failure rates of our HDD and SSD boot drives."

Whoa, they got some WDC 14 and 16 TB drives ! And 10 of the 8,400 WDC
fourteen TB drives have already failed !

They are moving to SSD drives for boot drives. They published the
Lifetime failure rates. 8 out of the 1,518 SSD boot drives failed
(0.65%). 559 out of the 1,669 hard boot drives failed (6.04%). "The
average age of the SSD drives is 12.7 months, and the average age of the
HDD drives is 49.6 months."

Note: The HGST drives have been really good drives compared to the
Seagates which are quite good themselves.
