The drive that failed earlier had some history of surface issues, as indicated by the SMART sector remap and read error counter climbing up over the years of usable. Despite these indicators, none of the parameters reach threshold and the drive worked fine. In the month after warranty expiration, the drive started failing rapidly (pending sector remap exceeded 65k) and is now basically unusable without significant risk of data loss.
The SMART reports on the second disk seems to show that it is in good condition over the entire time it has been operating. However, now 4 months out, this disk fails data integrity checks by the NAS and gets marked as crashed. It's possible that the drive would have failed earlier, as I discovered this disk failure after repurposing the disk recently (i.e. a lot of read/write over the entire disk), but none of the SMART parameters indicate problems despite monthly extended tests.
I've personally gone through about 20 hard drives in my life and these were the only two I have retired due to mechanical failure. While 'Green' drives are supposedly not designed for 24x7 usage, neither are my old PATA desktop drives I'm still running in a USB enclosure for the last 7 years. Granted, the data density on those old drives are much lower compared to the 2TB Greens, it is nonetheless worrisome that this drive only lasts 3 years tops. I wouldn't recommend this for anyone who keeps data for archival purposes.
It's pretty much a requirement to have to use their WDIDLE3 utility (DOS only!) to turn off the features that make this a green drive in the first place. But as a cheap non-green drive, their lifespan is too short. I've had to replace all of mine and those of two of my customers at least once under warranty.
The warranty is this drive's saving grace--Western Digital did take good care of me and sent out good replacements, most brand new and not refurbished ones. And I ran those until they died too before switching to Hitachi and Seagate.
One other thing: Western Digital's rebate processor has a penchant for lying about not receiving the rebates. I sent in two high-dollar rebates, and they were somehow "lost in the mail." Yet, in twenty years prior, the post office had only lost my mail twice, but here, two rebates sent to the exact same address mysteriously both got lost within weeks of each other? Plus, I sent in proof of my claim (photocopies of all documents), and they denied both.
If you do send in a WD rebate for a large amount, make sure it's sent certified mail. $4 to ensure the rebate of $50 or more is worth it. I've decided to simply not do business with WD or their rebate processor ever again.
I use Newer Technology's USB Universal Drive Adapters (UDA) to connect the WD Caviar Green drives to a USB hub (actually a "OWC Mercury Elite-AL Pro Dual" that holds two of the 1 TB drives & has a powered USB Hub). The 2 TB drives sit in a napkin holder (yes, kludgy & cheap!) and are connected to the USB hub & the Airport Extreme. The plastic napkin rack hold the 2 drives upright, reducing space required and which allows air circulation, not that they need it as they barely get warm during use.
Green wise, I doubt there are lower electricity consuming set ups. Using a "Kill-A-Watt" meter, each drive with its controller (Newer Tech's UDAs) only draws 4 watts while idle! When they sleep they draw about 2 -3 watts, which is probably for the UDA's nice bright LED christmas-type lights! I have not tested the drives' electricity consumption under heavy load (what's "Heavy Load" in a home?!), but The most I ever saw drawn was ~14 watts! As for noise, I thought my first 1 TB WD Caviar Green was broken as I did not hear a thing when I first set it up to format it. The 2 TB drives are also morgue quiet.
Formatting is simple for a Mac (don't know about others), as you just connect the UDAs to the drives & then plug them into your USB port. Using Apple's "Disk Utility" app in your "Utilities" folder in your Application's folder, you choose "Erase Drive" & I then chose the default "Mac OS Extended (Journaled). Type a name for the hard drive and in less than a minute, the drive is ready to go. Reconnect the UDA & drive to your Airport Extreme, and you've got 2 TB of networked storage available to all your computers on the network while using a tiny amount of electricity!
As for speed, I have done no speed tests, but copies to the drive ("writes" in proper parlance) over my wired, Fast Ethernet (100 Gbs) network the go at about the rate the Ethernet allows (~8 MB/s or 64 Mb/s, with the theoretical maximum speed of 100 Mb/s). Thus, the drives when on the network are likely limited by network speeds not the drives' speed. My WiFi network (802.11n) is even slower, thus making WD's Caviar Green drives perfectly suited for networked application. The worst thing about this set up is the couple second delay for the drive to first mount itself as it wakes from its sleep.
Western Digital's Caviar Green 2 TB drives will not only will you save electricity with this set up, you will save money on creating the networked storage I described, as each Newer Technology's UDA costs less than $30 and WD's Caviar Green drives are less than $45 / GB, which is an excellent value!

I was a little sceptical about the drive speed, but as I was only planning to use for files rather than OS, I thought it should be fine. In addition, though, I would think that the slower spin speed should make for a more reliable drive... however... there is no way to say how reliable the drive is without a few years' use.
I bought this to replace a 3 year old Samsung 1TB drive which had developed bad sectors. Every manufacturer can produce the occasional lemon and everyone is susceptible to plain old bad luck; one drive is never enough. If you store important files on your PC, be they photos, music, video or work files, you really really should back them up. Either invest in an another drive (internal or external) and/or cloud-based backups, such as MozyHome.
I'm impressed by this drive. For my needs, it seems perfect and I suspect that the slower spin speed should help to reduce wear on the unit.
overall for the price is an average product. if i had the option i would pay some more money to get the new version of this drive: Western Digital 2TB SATA 6Gbps Power Saving Internal Hard Drive OEM - Caviar Green
I have win xp and this drive seems to have issues, or seems to have issues with my motherboard (GIGABYTE P45 DS3L)
Installed the drive, partitioned it etc and then tryied to copy over my videos and it was transfering at 4meg a sec! went online to look for solution and it seems like alot of people have this issue and they all have different solutions, followed the recommend advance format proceedure, no change, re-alligned it no change, downloaded the widdle drivers no chance.
In the end in desperation i chance the sata slot and that seem to have done the trick, transfer speed of around 60meg, not the best but will do. Not sure about the reliablity yet, but had I know about the amount of trouble i had to go through to get it to work reasonably well, i would have spent the extra money on a normal drive.
This western digital drive has been super reliable and good value for money.
