Western digital greens should not be recommended for RAID anything. You can keep the drives in the computer while you use them and then take them out after you've powered the computer off such as with the device

At no point in my post did I suggest using WD greens for RAID. Personally I never used WD greens as the amount of friends I've had come to me with dead ones has kept me well away.

I suggest you update the firmware of your greens if you still have them and hadn't done so.
The spin up / stop time of the greens has been fixed about 6 months ago by WD (as well as the heat). What they did was add a delay to the spin down or stop of a few seconds. This way the HDD will not spin down or stop immediately after writing data in a raid.
This problem was mainly with old drives below the 3TB mark. The 3/4TB ones have a more improve firmware and a new arm. The motor is pretty much the same but the firmware helps it a bit.

I used to use a 6 or so years old perc5 controller with new HDD green drives. It never kicked a drive off the raid because of spin ups.

I disabled the idle timer in the Greesn before installing them in the NAS. They don't stop until the NAS is shut down. I have Reds and Greens side by side, all idle, and the Reds are consistently cooler than the Greens.

I do something completely different, thought it's because it's a multi-purpose system (media server, pc backup, other). I run a WHS2011 server with approximately 75TB (20 x 4tb, which turns out to about 75 usable after formatting). Certain folders are replicated, meaning the files are copied to other drives in the pool. Those files also get backed up to external drives on an irregular basis (depends on how much I've shot lately and added to the folder). All of those files are secondary to the original data residing on my pc drive.

As for drives, after 2 home servers, I gave up WD as a brand altogether - just way too many failures. I strictly buy HGST (formerly Hitachi) now. And yes, I know WD bought the company, but I still think the HGST drives are made at the Hitachi plant, and they have been (knock wood) rock solid reliable for me.

Same here. You can often get new Hitachi enterprise class 2 & 3TB drives on eBay at very good prices. Many techs I've worked with think the Hitachi Deskstars are just as reliable as the Ultrastars. I've never had a WD failure (I have two that have been running for 12 years - maybe I'm just lucky) but now I only buy HGST drives.

Hitachi nickname found often on the web...'DeathStar'

In three years I have had two WD harddrives fail...one after a few months infant mortality, the HP warranty replacement drive has just failed, 38 months later. And about 2 years ago a WD MyBook failed, but I pulled the drive out of the enclosure and installed it in a dock, and it worked...the MyBook support electronics in the enclosure had failed, not the harddrive itself.

A few years ago, when I was about to purchase several TB+ size drives for building up my server & local hard drive storage capacity, I did some digging (on the internet) on brand & model reliability. There was not a lot of what I would call non-anecdotal data. Google did put out some data based on their experience.

Anyway, as I recall, leaving out the occasional batch problem, there were no significant differences across the brands.

Presently, there are only 3 manufacturers left in the business: WD, Seagate, and Toshiba. The diagram below is from wikipedia, and it somewhat misleads regarding Hitachi. While WD was required as part of the acquisition of Hitachi's hard drive business, to divest assets to Toshiba for 3.5" drives, WD's HGST subsidiary did retain some 3.5" product lines.

IMO, RAID is the LAST thing I'de suggest for a home user.

RAID is for uptime, not a backup.

here's my setup:

PC for developing photos : 2TB.
Raws backed up to NAS, and External 2TB.
JPEG developed are backed up to NAS at home, NAS at my moms, and a different 1.5TB External.

it would take quite a disaster to wipe out my photos. I've also considered cloud solutions, like facebook or flickr, and keeping the photos to private.

at home i'm running 40+TB server.

I go though (add-remove) hard drives all the time.

my piece of advice, stay away from WD Green, a big no-no.

Hitachi are the best option, Toshiba bought some tech and factory from Hitachi, so Toshiba hard drives can be acceptable too, but still to new to 100% recommend them.

Seagate are hit or miss, in past seagate had a lot issues with their firmware.

WD, Blue and Black are ok, Red to soon to tell, Green are horrible.

I've had ok luck with my greens, granted, they are only turned on to backup, and off as soon as they're done ;)

i had 7-8 of them at one point from different batches, 5-6 of them failed, after RMA i got rid of all them.

at work I do IT, and I also fix PCs on the side, and quite often I see WD Greens fail, more often than any other type of HDD.

Which MIGHT just mean they SELL more than any other type. IOW, you can't tell from your view of looking only at PCs brought in for service what the failure RATE of WD Greens is.

haha, knock on wood. I see some funny perspectives at work. I spec'd out this HP machine that I thought was great at the time, and mine is littered with problems. I think it's utter crap, but my boss is fairly happy with his, and he has the same nags as me!

He's so grateful that I recommended the item for him, while I thought I made a very poor choice :D

I think I run nothing BUT greens at this point, 4 in two separate NAS, and 2 external. My luck. But aside from personal luck, I usually gravitate to amazon/newegg reviews. If it is high rated there, it generally translates to good product. Some reviews are fabricated, but that is not the norm.
