As hard drive capacities increase, the power required to run those drives increases as well. WD Caviar Green drives make it possible for energy-conscious customers to build systems with higher capacities and the right balance of system performance, ensured reliability, and energy conservation.
Reduced power consumption - WD has reduced power consumption by up to 40 percent compared to standard desktop drives with the combination of WD's IntelliSeek™, NoTouch™, and IntelliPower™ technologies.
Helps enable eco-friendly PCs - WD Caviar Green drives yield an average drive power savings of 4-5 watts over standard desktop drives making it possible for our energy-conscious customers to build systems with higher capacities and the right balance of system performance, ensured reliability, and energy conservation.
Cool and quiet - GreenPower™ technology yields lower operating temperatures for increased reliability and low acoustics for ultra-quiet PCs and external drives.
Massive capacity - Capacities up to 2 TB offer the most available capacity for storage-intensive programs and space-hungry operating systems, like Window Vista®, with plenty of room left over for photos, music, and video.
Perfect for external drives - External drive manufacturers can eliminate the need for a fan in a high-capacity product with a WD Caviar Green drive, the coolest and quietest in its class.
IntelliPower - A fine-tuned balance of spin speed, transfer rate and caching algorithms designed to deliver both significant power savings and solid performance.
IntelliSeek - Calculates optimum seek speeds to lower power consumption, noise, and vibration. View demo >
NoTouch ramp load technology - The recording head never touches the disk media ensuring significantly less wear to the recording head and media as well as better drive protection in transit.
Perpendicular Magnetic Recording (PMR) - Employs PMR technology to achieve even greater areal density.
StableTrac™ - The motor shaft is secured at both ends to reduce system-induced vibration and stabilize platters for accurate tracking, during read and write operations. (2 TB models only)
Low power spin-up - WD Caviar Green drives consume less current during startup allowing lower peak loads.
Advanced power technology - Electronic components deliver best-in-class low power consumption for reduced power requirements and increased reliability.
Environmentally friendly PCs and external storage requiring lower power consumption and cool, quiet operation.

The drives are specc'ed to a max lifetime LLC of 300k, so you can see where this is heading (groan). It's very poor that there hasn't been a fix for this straight off the bat after 3-4 months since it was first noticed, other than WD telling people to attach the drives to a windows pc and run wdidle.exe to 'lessen' the problem (this reduced the problem by about half).
Kinda wishing I'd bought Seagate Barracuda's instead.
Bad Choice, my fault that I did not do enough research on the WD Green Drives.
In just 2 days I had a Load Cycle Count of almost 1000, ridiculously high!
LCC: the number of times the disk heads are parked and unparked. The more often the faster your drive will eventually fail. At 500 LCC/day this will be very very soon with a mean-time-to-failure of about 300,000 thus much sooner than even the warranty.
It turns out that the firmware that WD installs on the drives haan absurd error, it parks the heads after 8 seconds of inactivity ! Unusable in the real world.
There is no firmware update to rectify this and instead one is pointed to a WD utility -WDIDLE3- which is time consuming and impractical for the average computer user - need to open up another computer, connect to SATA drive, create a DOS boot disk, run utility etc. etc.
Why WD did not simply issue a firmware update is beyond me and why it still ships them with this firmware is inexcusable.
Two other issues specific to REadyNAS Duo:
1. WD seems to be shipping drives with 4K byte sectors instead of the old 512bytes. Not a problem but the firmware on the RERadyNAS duo does not handle these new expanded sectors well (unless you want to use a 4.1.7 BETA firmware - in the works for almost 6 months now!) which reduces write performance considerably.
2. The WD drives to not recognize some of the commands from the DUO and thus you end up with a lot of ATA errors when the Duo boots up. Supposedly not much of an issue but you never know since many people have complained about this as a potential performance impediment.Read more ›
This is different to a normal Simple Volume that can be partioned into different Drive Numbers. A Dynamic Volume works differently and will not accept partioning by Windows or Third Party software.
Also my Acronis TrueImage software would not backup to a Dynamic Volume if I wanted to recover my sytem from an emergency boot up CD which is often the most likely eventuality.
All attempts to convert it from a Dynamic Volume to a Simple Volume through Windows using Disk Management were "greyed out" as unavailable actions. Partition Commander 11 would not work on a Dynamic Volume either.
The only way I could delete the Dynamic Volume was to use an excellent Freeware utility ISO file called Parted Magic which when put on a CD enabled me to boot into Linux and delete it before booting back into Windows and mounting it as a Simple Volume which can be partioned.
I hope this saves you a day and half that I spent resolving it.
Within a month it marked drive 1 as degraded (It crashed), but it managed to rebuild the volume and so I went on quite happy.
Now, less than two months later it has marked the same drive as degraded again and is now unable to recover the drive.
In hindsight, I really should have read other's feedback on this drive more carefully. I am now going to buy another brand and try to get my money back on this one.
If you do insist on buying one of these drives, my advice is to keep the receipt and the box handy ;-)
Update: 3 months later and the second disk has degraded and will not recover :-(
When connected to the PC, the faulty drive was freezing/locking up the computer, even when copying small files. After about an hour, it just comes up for about 3 seconds, and then shuts itself down, so nothing that can be done and has to be replaced. On a positive note, I'd rather have a drive failing right away than after a few months.
Working drive seems to be reasonably quick, and stays cool. Quiet too.
One annoying fact: to use at full speed with Windows XP on one partition, you need to set a jumper on two pins. However, no jumpers are provided! If you don't have spare jumpers from other drives or DVD drives, then it's annoying. Surely, WD could afford to put one jumper in the box. The drive is using some special formatting (Advanced Format Technology (AF)), meaning that it is not optimised for Windows XP.

I wasn't aware at the time of purchase this drive parks the read head every 8 seconds. That's insane. As result, the drive was worn out much sooner than expected and died on me. Read morePublished 4 months ago by E71
