OT; Green is not always good.

I'm putting together a new server and was about to order four 2-terabyte Western Digital "Green" enterprise hard drives for it. 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. -- I can assure you that the road to prosperity is not paved with fleabagger debt. |
