I hate to be so negative on the GREEN line because I think they are ok for general use. But they are dated in design and it's not 2010/2011 anymore. They really don'y have a power saving advantage I see over RED or even more modern designed HDD's. That was originally the benefit two years ago but many others have caught up in this area. Noise also. I think modern HDD's are much quieter than just a couple years ago. Warranty is a disadvantage for WD GREEN too. Shrinking the warranty on green and providing a longer warranty on a RED drives just suggests to me a long term reliability disparity. If it did not save them money then why do it ? If they know the greens would last at the same failure rate and long term use- then why not hold this advantage over Hitachi or Seagate or Samsung ?
A newer/better RED drive uses less power than a Green Drive. It performs better too. And- It has a longer warranty. It might be -$15 more expensive on average street prices daily but if catch a deal they are often the same prices. RED does not have the intellipark feature for headparking- and it is recommended for 24/7 use. I just don't see much value in GREEN drives today. I think many storage solutions today are based off servers and NAS boxes- for which RED and others make much more sense over a green drive IMO. But- Green holds a nice niche as a solid choice for in PC basic storage. So inside a HTPC or a simple desktop it makes sense. That was always it's original intended purpose. The consumer habits and applications have changed since then and that is why you see RED's and more appropriate drives recommended for RAID, NAS BOXES and servers.
Originally GREEN were available for a great price- and they were on a good trend of HDD's to be more efficient, cooler, quiter. Today they have lost much advantage in cool/quiet/energy since competition has improved in these areas. Greens are also not seen for great prices anymore. A great deal is the only reason I would see for buying a green drive today. If it's cheaper it's probably a solid move to snatch one and use it. If it's not cheaper- I would look for a cheaper drive or a better drive model for the same price.
Seagate 3TB's are the cheaper alternative. They are pretty solid performers, not terrible in energy/noise/heat and have a decent track record. It's a more modern HDD design. Pretty much any 3TB drive is the more modern design FYI. Smaller drives you would need to research more.
Green is not that bad- but there is some suspect reliability issues that may or may not be significant or true. I've personally had bad luck but I am open to the idea I might just be a personal experience that is not indicative of the general population.
I'd buy a green for less $- but I'd buy a RED or a Seagate for the same $$$.Here is a good comparision:http://www.tomshardware.com/charts/hdd-charts-2012/-26-Power-Requirement-at-Idle,2917.html
