    “Backblaze Drive Stats for Q2 2021”
    https://www.backblaze.com/blog/backblaze-drive-stats-for-q2-2021/

    “As of June 30, 2021, Backblaze had 181,464 drives spread across four
    data centers on two continents. Of that number, there were 3,298 boot
    drives and 178,166 data drives. The boot drives consisted of 1,607 hard
    drives and 1,691 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. Along the way, we’ll share
    our observations of and insights into the data presented and, as always,
    we look forward to your comments below.”

    “Zero Failures
    Three drive models recorded zero failures during Q2, let’s take a look
    at each.
    6TB Seagate (ST6000DX000): The average age of these drives is over six
    years (74 months) and with one failure over the last year, this drive is
    aging quite well. The low number of drives (886) and drive days (80,626)
    means there is some variability in the failure rate, but the lifetime
    failure rate of 0.92% is solid.
    12TB HGST (HUH721212ALE600): These drives reside in our Dell storage
    servers in our Amsterdam data center. After recording a quarterly high
    of five failures last quarter, they are back on track with zero failures
    this quarter and a lifetime failure rate of 0.41%.
    16TB Western Digital (WUH721816ALE6L0): These drives have only been
    installed for three months, but no failures in 624 drives is a great start.”

    Yup, for spinning drives I go with WDC.
