Size: 3 TB
I bought 2-3TB drives for my Synology NAS Synology DiskStation 2-Bay (Diskless) Network Attached Storage DS212j (White). I've only had the drives on for one day but after reading about all the drives that fail after a few months it seems the problem is the head parking itself every 8 seconds if no disk activity. The only reason it does this is to try to save power. Each park results in a load/unload cycle. Most modern drives are rated around 600,000 cycles. Depending on how your system uses the drive, your drive should only have 10-200 cycles per day, but some these Western Digital drives are reporting 3000-5000 cycles per day. This will surpass the 600,000 cycle limit in a few months. You can get the cycles from S.M.A.R.T. or from third party software. Think of starting your car and turning if off every minute, 24 hours a day. Your starter would only last a month or so and then fail instead of lasting for years.

The first thing I did with my new drives was to run the WDIDLE3.EXE utility on them to disable the 8 second head parking. You can also change the head parking to something like 5 minutes, which would make a lot more sense than 8 seconds. To use this utility, you have to run it from a boot disk at the command line. This means you have make a cd/dvd/floppy that you boot from and get a command line prompt such as A:\. At the A:\ prompt type in WDIDLE3 /r to get the current setting (mine said "Idle3 Timer is enabled and set to 8.000 seconds"). After I ran WDIDLE3 /d to disable the timer it said "Idle3 Timer is disabled." You could also run WDIDLE3 /S300 to set the park time to 5 minutes.

I have tons of WD drives and they've been around for awhile (including two 2tb 'green' drives), so I decided to give this one a chance even with the half/half ratings it had.

This drive is great! Popped it into my esata dock, turned it on, and windows disk management saw it instantly, as the full ~2.7tb. Initialized it, making sure to pick GPT, and then formatted it. Windows saw the whole partition, no fuss.

To test the drive, I did a low level format, then a disk check. When both came back fine, I copied as many files as I could fit on the drive, and then did another disk check. Came back fine again, so I ran DiskMark to see what speeds I was getting. When the drive was almost full (~3gb free), I was averaging around 30-40MBps. after I reformatted and ran the test again, I averaged ~60MBps. Compare this to a smaller hard drive and you will see that this is considerably slower. (I just ran DiskMark on a full WD 500GB drive that's about 5 years old, and it averaged 80MBps)

However, 30MBps is plenty of speed to stream movies, which is what I'm using it for. This drive won't make the best boot drive, but it makes a great archival one.

As I've only owned it for about a week now, I can't comment on long term reliability, but I will update if anything happens.
For now, I do recommend this drive.

Edit 11.15.11
After owning this drive for a couple of months now without any failures, it is a very attractive option. However, your mileage may vary, since mine seems to be a bit slower than a friend's who bought the same version (I was getting around 60-80MB/s while the drive was pretty full when I was copying files to his). All-in-all it's a good drive.

I have a total of seven of these drives between 6 on a raid array on one PC and one as a data drive (non raid) in another PC.

They are slower at RPM speed than some other drives, at 5400 RPM so if you are someone who "needs" a 7200 RPM drive then you do not need this.

They are however the CHEAPEST, MOST RELIABLE CHEAP drive out there. Unlike some brands who will sell you a 5400rpm drive for this, or the various drawbacks from externals, this drive is inexpensive, not annoying in its "green" power management (or needing to have it shut off) and its fast, I get good speed in my 6gb/sec Sata3 port, and overall think its great that for this price, I get a drive with a 3 year warranty, reasonably fast transfer rates despite a lower RPM (RPM is not everything apparently) and its a Western Digital (and not lower on quality) for the price.

Western Digital have been reliable drives for me, for many years. I have some going back as far as 8 years old and still running (that does not mean one has never died) but it's not common. It's more common that the storage size becomes too small for me and gets it shelved than the drive fails.

I am optimistic by the early performance of these Caviar Greens that I will continue to use these for a 3tb drive. For 2tb drives I prefer the Caviar Black (which is not made in 3tb size). I was apprehensive to go to another brand, so chose WD's lower line rather than risk a brand who has not performed well for me for years.

Five stars are for the value, and the fact it delivers.
