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 ?
just got myself a netgear ReadyNAS 1500 for $450
8tB :)

maybe 8tb's worth of drives.. storage capacity wont be anywhere near that... [smilebigeye]
Yep, call WD and *insist* on up-front replacements.Quote:

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.Quote:

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.
