    It's all a bit hard to get these replaced.. UMART basically tried to fob me off to WD.. and either way its 4 separate returns, waiting for the replacement with my NAS inoperable, I'll probably end up buying a new drive and rotating thru the replacements,, anyone think of a better way?

    Why is power saving a bad thing ? I gather this is no spin-down ?

    Yep, call WD and *insist* on up-front replacements.

    WD using SMR on REDs - Storage

    Correct. Back in the mid 2000's I had a good conversation with a storage engineer at Maxtor. The result was "for best drive life keep them spinning and keep them warm". Where "warm" was over 25C and under ~45C. Below 20 and above 40 platter temperatures they have "trouble" writing to the platters.

    When I worked out the additional power cost of keeping them spinning vs the cost of new drives, keeping them spinning was cheaper. For example, a drive costs me ~$15/yr in power. Cost of one drive is 20 years power for the drive, so the longer I keep the drive the more I'm ahead. Unless I run out of space, I'm generally replacing about every 6 years, but I absolutely replace before ~70,000 hours.

    Having said that, my arrays live in a granny flat in a pair of chassis. One 15 bay and one 24 bay. Noise isn't an issue so they have decent cooling and a separate split A/C to make sure the environment doesn't exceed 30C.

    One anecdotal data point for you. I'm sure there are people who have arrays with full power saving enabled and last just as long. A lot depends on usage patterns also.
