I'm putting together a new server and was about to order four 2-terabyte

I've never really thought about why these drives are called "green,"
other than they are supposed to use less power than "non-green" drives.
Obviously, they do this by shutting the drive down when it isn't being
accessed.

Apparently, though, when you use "green" drives in a server, you end up
with a dramatically high Load/UnLoad Cycle Count, and this can lead to
premature ejac-, er, drive failure.

There is a way to turn off the "green" on the WD drives, by adjusting
the drive's idle timer to lower the Load/Unload cycle rate, but it is a
pain in the ass, involving preparing a DOS boot disk, installing the
drive in a computer, and running a program. Not difficult, but I don't
have a "Windoze" computer anymore that can boot up into DOS. :)

I'm guessing the "green" drives of other vendors will behave similarly.

Sheesh, I never learned any of this stuff in my college English classes.
Even an O.F. like me is not too old to learn.

Failure of drives is exclusive to the (lack of) quality of the drives.
How much power they use is not a factor. If anything, lower power, less
heat and slower access times for less vibration should actually be better.

I would use Seagate drives. And forget DOS/MS products. Use Linux.
Ubuntu or Fedora. No way to turn off green, they run slower, consume
less juice by design.

Use HW RAID on the boot disks if the mobo supports it.


According to Western Digital, the manufacturer of the drive,
dramatically high LOAD/UNLOAD cycles lead to premature disk failure.

Your argument is with WD, not with me. I suspect they know more about
their drives than you do.

Harry's either too stupid or too idiotically boorish to take good
advice...
