high performance, 5 year warranty, self-rebuilding raid mirror
If you want the best performance, you would want to use it as eSATA. This would mean a cardbus or expresscard eSATA adaptor on a laptop, for example. But here is the one star that I have taken off: at this price, it still does not come with an eSATA cable! It has cables for USB and the 1394, but no eSATA. I have not had the chance to test it in eSATA because of the cable...

If you want the best performance, you would want to use it as eSATA. This would mean a cardbus or expresscard eSATA adaptor on a laptop, for example. But here is the one star that I have taken off: at this price, it still does not come with an eSATA cable! It has cables for USB and the 1394, but no eSATA. I have not had the chance to test it in eSATA because of the cable. The USB2 speed is good enough for my archival application. I've also read around and eSATA is not faster than USB2 by much in real life (maybe 25MB/s vs 30MB/s).
The 5 year warranty is industry standard and is reassuring. And by the time it's up, you will want a larger storage anyway. :P But you must keep in mind that that if the controller in the enclosure dies, your whole array dies. Hopefully the controller didn't write bogus information into your harddrives and then hopefully WD will be able to ship you a new enclosure and you can recover that way. (This is the one weakness of having RAID 1 as the only copy. Be ware: a faulty controller can corrupt your data or even wipe your drives clean. Don't let that be your only copy.)
Cost-wise, each of its 1TB harddrives retails at about 180 as of this writing and you still need two enclosures to mount them externally. That means you are paying 470 - 2*180 = 110 for WD's own enclosure. It may still sound like a lot for an enclosure but the pros of this one outweight the cost and cons:
- The enclosure does RAID 1 (mirroring) in its hardware, no real cons here as long as 1TB+1TB mirroring is good enough for your application.
- Fanless: Less noise and it's really silent, but it also runs rather warm even with air conditioning. I do note that there is a temperature sensor that will stop the drives when overheated. So there is technically no worry, unless the temperature sensor itself dies... And being fanless is what makes the 5yr warranty even better. I've replaced one too many fans in my enclosures. (Many fans die within 3 years...)
- Self-rebuilds: After replacing a drive, it will rebuild in several hours. Good: completely automatic. Bad: it does this offline so the data is not accessible while rebuilding.
- Green assembly: I should note that you can only use WD's own "harddrive assembly" in this enclosure. You cannot (at least within the warranty's limit) use your own harddrives, not even WD Green Series retail ones since they do not come with the assembly hardware. See the manual if in doubt.
In all, highly recommended if the capacity suits your need.

I have been using the WD Studio II 2TB on my 2008 iMac OSX 10.5.6 for two weeks. Connection: firewire 800. Today, it did not mount when I booted the computer.
Checked the WD Website Knowledge Base.
Discovered two things:
1. Knowledge Base Answer 1697: "This issue is caused by the external hard drive's built in auto on/off functionality not correctly receiving a command from the computer system to wake from a power saver mode."
Why does the auto on/off functionality not correctly receive the command from the computer system? WD goes on to suggest installing their WD Drive Manager.
Well, WD Drive Manager is already installed, how else could a user have arrived at this impasse to begin with?
And then they suggest to dismount the drive. How do you dismount an unmounted drive?
2. Knowledge Base Answer 1680: "This is an technical limitation between the FireWire interfaces on the Macintosh computer and the external hard drive."
By "the external hard drive" WD means THEIR brand of external hard drive. I have never had this specific problem with any other brands of external hard drives connected to my Macintosh computer.
When is WD going to fix this "technical limitation" that they have built into their Studio II external hard drive? I would say, that is a pretty serious "technical limitation."
1680 goes on to explain the workaround solution, essentially a routine disconnecting the power cable and reconnecting. Nice.
My hope is that this entire situation is the result of following the apparently misleading instructions shown in the Studio II manual: chapter 7, "Turning Off/Disconnecting the Device."
Since "Auto-off" is the first entry in this chapter, it leads the user to believe that this is the preferred way to operate the drive. Guess not: as it turns out, the hidden "technical limitation" of the firewire connection will eventually cause the problem I have described. I suppose I can't rely on "Auto-off." Use "Safe Shutdown" only, even though the instructions in the manual differ from the instructions presented in WD Knowledge Base Answer 976!
And, speaking of conflicting instructions, compare WD Knowledge Base Answer 1386 with the Auto-off instructions in the manual.
Based on all of this information from WD, conflicting and otherwise, my guess is that the Auto-off feature is problematic (at least with Macintosh computers) because of firewire "technical limitations" caused by the WD external drive design. This fact, if it is a fact, should be expressed clearly in the manual.

I thought this drive would finally release me from my worry that my backups will melt away before my eyes. The Greenpower concept seems well and good but I don't know about the long term viability of putting two of these drives in the same tiny enclosure with no active cooling.
After about 20 minutes of transfers I opened the lid and the drives burned my hand. I put a digital thermometer on the inside of the case between the hard drives and the air in there was 51C. The drives were probably between 60-70C as I can't be sure. Compared to my internal WD Caviar 500GB drive that runs at 32C when cooled by the case-fan the the My Book worries me. Not that I will be running the drives for 2 hrs at a time all the time but it happens.
Otherwise, I tested the RAID 1 feature by removing a drive while the unit was powered and when I replaced it, the rebuilding process automatically began. If I unplugged it during the rebuilding, it would resume when I plugged it in again. Again after only 15-30 minutes of rebuilding the drives were too hot to touch again. I can't imagine how hot the non-Greenpower drives get.
The power consumption ranges from 4W when off to 16W when rebuilding.
The interface is quite speedy as well. Roughly writing at 35MB/s using USB2.0.
I think I'm going to return the drive and build a NAS with two of the same drives inside for peace of mind.

Would be great, if the silly thing didn't unmount itself for no reason. Usually when there's no activity, although I dread the day is happens in the middle of a video edit. (There are reports around that it does happen.) For some reason, it just unmounts itself. Disappears off the desktop. No reason. Only comes back with a physical push of the power button. Of course, Western Digital says the problem is with Mac OS, not with them. No other drives display this problem & this is a commonly reported problem in forums.

I purchased this drive to go along with my intel mac. I was previously a happy lacie owner, but since WD came in at such a great price and was listed as great with macs, I went for it.
What a mistake. For the first month, it worked well... a bit slower than my lacie, but still worked. Then, all of the sudden, it began to dismount itself from my computer. I am currently using Lightroom to edit my work, and when the drive would fail, Lightroom would loose the catalog. When you have 500+ images to edit and the drive dismounts every 45 minutes, this can become a huge issue.
So, I did some further research and found out that several other intel mac users are having the same issue with this product. This is very frustrating as it is advertised 'for your mac'. Most of the other posters mentioned that the drive worked well for about a month and then started having issues.
I called WD, and their customer service department was actually very helpful. The offered to send me a new unit, even though that unit would likely have the same issue down the line. I understand that there was not much they could do for me at WD, but they were concerned and helpful just the same.
Luckily for me, the customer service dept at Amazon is rockin' awesome and is allowing me to exchange the WD for 2 lacie units even though I am slightly past the 30 day return policy mark. While I have never had to return an item to Amazon before, I am very comforted to know that the customer service dept is really looking out for their customers.
If you are using an intel mac, I would move on from this product. It is not worth the headache. However, you can feel confident making your purchase from Amazon...

With the ever increasing size of my digital photo library I needed to increase the size of my back-up drive. I use this unit with a Mac and set to a RAID 1 configuration for mirrored storage. RAID 1 knocks down the usable area to 931 MB. It seems to work with Apple's Time Machine back-up program and OS 10.5. I did reformat from my Mac as I have always found I have to do for external drives. After about a month, everything seems good.

I have six My Book Studio drives in the 1TB capacity for storage in my photo studio. I love their speed, reliability, and trouble-free ease of use -- they have worked great for me.
The new 2TB WDH2Q20000N I got a week ago has not been a pleasant experience. I could not get my recent iMac 24" to recognize it as either a Firewire 400 or Firewire 800 drive. I tried it daisychained with other drives, as well as directly connected to the ports as the only drive -- no joy.
So I reluctantly hooked it up via the slower USB 2.0. Even this is a mixed bag. Once I get the drive up and running, it's OK, but if I power down my system, I have to physically disconnect and then reconnect the power and USB cables before the drive is recognized.
To make sure I wasn't doing something stupid, I upgraded the firmware in the drive, and reinstalled the WD software on my iMac. No change. After much digging around the WD support site, I found some mention of these problems. Not easy to find, and no real solutions offered.
I have no idea how this drive would perform in an eSATA environment, but for the Intel iMacs, I call it a total failure. Very disappointing.

BOTTOM LINE UP FRONT:
PROS-
-Exactly as advertised by Western Digital
-Drive/RAID Management Software is very easy to use & works well in OS X
-Works very well with AirPort Extreme Base Station
-Excellent as an AirDisk for Time Machine (follow process listed elsewhere in reputable Mac Forums)
-Includes FireWire 800/800, FireWire 800/400, and USB A/Mini-A Cables (the FireWire Cables alone are a big plus for new Mac Owners)
CONS-
-Included WD Anywhere Backup is a waste of time - does not do full system backups
EXCRUCIATING DETAIL:
I purchased this drive to run it from an AirPort Extreme Base Station (AEBS) as a self-mirroring Network Attached Storage (NAS) volume in a mixed-platform environment (WinXP and OS X).
MAC EXPERIENCE: Initial set-up was a snap by connecting the drive to a MacBook Pro via Firewire 800 and using the included drive/RAID management software to configure it to be a RAID 1 HFS+ volume. After following the processes to set this drive up as a Time Machine target, it has performed flawlessly. PLEASE NOTE: Using any drive as a Time Machine target via an AEBS IS NOT SUPPORTED BY APPLE.
WinXP EXPERIENCE: This drive was made available to my Windows Platforms via an AEBS. Mounting this volume was handled automatically by AirPort Base Station Agent. PLEASE NOTE: If using this drive on an AEBS in a Windows Environment, the AirPort Base Station Agent translates HFS+ File System into FAT32 in real time. For most new applications, this will not be an issue BUT some legacy software will either hang or post an error if writing a file larger than the 4GB limit in the FAT32 specification (this happened to me with Ghost v9), but I was able to establish a workaround.
OVERALL: This drive has performed HOURS of continuous READ/WRITE without any of the disconnect/dismount problems reported by other users (please see my note in the paragraph above as to my theory on why that happens). The Power Save mode is mostly transparent although there will be a minor delay as it restores itself. This is my third WD "MyBook" purchase, all of which have been dependable workhorses.

While this drive works correctly with USB 2 and Firewire, there are issues with Snow Leopard...
Software which manages the drive's display (e.g. shows how much free space is left on the drive), as well as permits changing the drive's RAID mode has never been updated for Snow Leopard. The version which is still distributed by Western Digital on their web site throws errors at a rate of 10 per second with Snow Leopard. While Western Digital has had more than enough time to resolve this problem no resolution has been forthcoming, all the time marketing the drive as compatible with current Apple systems.
Another issue is related to employing the SATA interface with a Mac. In short if the drive falls asleep on its own (see countless other reviews on this point) and the host Mac system goes to sleep (manually or after a period of inactivity), the SATA interface on the drive freezes. The only recourse is to disconnect both the SATA interface cable and power cable, thus resetting the drive. This issue was raised with Western Digital in 12/09, but to date no firmware update has been forthcoming.
Thus use this drive with USB2 or Firewire, ignore the display free space feature and be prepared to setup the drive's RAID mode on a Windows computer. If these conditions are acceptable then this drive works ok with Snow Leopard. If not, then don't buy this drive.
One note. This drive has no fan, so it makes minimal noise. This could be a game changer for some users. In fact this is most likely the best reason to purchase the product over many other alternatives.
Update:
With older (e.g. 2006-2007) Mac Pro systems, this drive is not bootable via the 800 Mbps Firewire port. Given that eSATA isn't supported either (an Apple thing), your only option is booting from USB. Yes that is right USB! So much for using SuperDuper! or the like. Note that you can boot from the OSX distribution DVD and restore a Time Machine backup via the Firewire interface.
Western Digital to date (Aug 2010) still hasn't released a Snow Leopard compatible version of the drive manager software. At this juncture it is clear that this software will never be updated for Snow Leopard.
I never did find a "good" solution for the SATA issue cited above. At this point I use the eSATA connection for full system backups and revert to Firewire for day-to-day Time Machine backups.

Great design; small foot print and even though the case is plastic it seems very sturdy. Very quiet. Take your pick of interface: eSATA, FW 800/FW400, USB 2.0... AND 5 yr warranty.
This drive comes out of the box Mac ready. I am using WinXP... the included SW bundle didn't seem to have any Win "setup". I had to call Tech Support and download WD Drive Manager. Once that was installed the rest of the setup was a breeze. I chose "Quick format" so it formats as you add data... instant (WD tech support told me it would take ~12 hours for a full format) and RAID1 (no sweat... easy just chooose RAID 1 or 2 from WD Drive Manager). I found that USB was too slow so I added a CardBus FW800 card (Startech CB1394B3 ), much faster now. My next laprop will be a MacBook Pro... then I will use the fastest interface... eSATA. No eSATA cable was included.
