WD Green drives

[drissical]

WD Green drives use something called 'intellipark' which is what gives a lot of the power savings for the drive. There is an article about that feature causing early failure in the drives.

I find this interesting because I was looking at putting green drives in to my system purely for storage. I am curious if the machine is just sitting there if greyhole does constant accessing or anything that would cause extra read and writes to those drives. There are work some ways to work around it but it seems counter productive to the nature of the drive and just seems like you might as well get something else.

Some other things I found interesting:

Google search just brings up related stuff.

Any thoughts to this?

Apologies if this should be in the Greyhole thread, figured it was more top level as there is nothing wrong with greyhole just a concern for a piece of hardware.

I've had one of these fail on me in my greyhole pool. RMAd it and no issue with the replacement.

Drive failures are essentially random in every few 100000 drives. I would personally prefer better performance with 7200RPM drives that sleep frequently.

the part that worried me is a drive in a linux box on 24/7 with intellipark can go out in a matter of months aside from the random failures that one would normally deal with.

I need some help figuring out if the Red drives that are designed for a NAS environment will make any real difference over the Green drives. From what I found the Green drives are far from ideal for NAS Raid environments. Amahi (atleast mine) is not a Raid setup as greyhole is just too awesome to need one. So what I am curious of is with the stuff about the drives failing in raid setups is this something that i would even have to worry about in an Amahi setup as for sake of argument the drives are just plain desktop drives in there. I am assuming that if no one is access files at best greyhole might access the drives once a day correct? If so that sounds like Green are going to preform just as well as Red in most cases.

I would say you are correct for the most part. Greyhole typically only runs when there are tasks. If you change any file on the HDA in the pool, then it will be working.

If you are using max copies and a drive fails, no biggie. There will always be a good copy on one of the others. I think pretty much any drive will work fine for Amahi using Greyhole.
