4 out of 5 eggsWD MyBook

Pros: Configured as a RAID right out of the box. Recognized on both Apple MAc and Windows OS platforms. Have had it for over a year now and hasn't given me any problems to date. Works great as a backup drive for my music, movies, photos.

Cons: No eSATA or firewire 400/800 connections for faster data transfers. The USB connection on the back is poorly made. The UBS cable falls out a lot so I had to use a plastic cable zip tie to secure it to the back of the drive. Also you cannot use any other drive other than WD Green Drives. I tried upgrading it from two 1TB HDD to two 2TB HDD and it wouldn't recognize the drives because they were not Western Digital Green Drives.

Other Thoughts: All-in-all it does what it's supposed to do, hasn't failed on me yet, and it's always a good idea to keep your important data backed up. Plus now it's way cheaper than it was a year ago. I give this product 4 eggs.

4 out of 5 eggs

Pros: Pre raided to 1TB. Nice to have stuff backed up. Looks nice.

Cons: Software seems a tad clunky - reason for 4 eggs.

Other Thoughts: Good deal - I'm pleased enough with it that I bought a 2nd one.

5 out of 5 eggsI have 3 of these

Pros: Mirrored - 1 TB on the desktop, good transfers speeds.
I am buying a 4th as I write this. These are used for archiving of audio recordings until burned to DVD for long term storage. They have worked flawless.

Cons: The case is a little flimsy, for the size they could make it sturdier. but not bad overall ... not worth loosing an egg

Other Thoughts: No vista 64 issues here .. except for changing the mirror settings. Doesn't work with my version of the software in Vista. Changed the settings on a XP machine and moved it back. Glad the price has dropped .. even a better deal !

3 out of 5 eggsFailed after 1.5 years

Pros: - size - up to 2 TB storage
- configuration options - RAID 1 or... not (don't recall if not means RAID 0 or jbod)
- simple to use

Cons: - physical size - rather large for what is available lately
- failed after one and a half years use - corrupted files and write failures
- no eSATA

Other Thoughts: Used as a back-up for large set of .tif files, configured as a 2 TB drive.

Stopped working last week; misc. read and write issues (hanging on reads, failed writes to disk) but I notice the top cover has popped open. I'm wondering if someone in the office dropped it, and isn't fessing up? Fortunately we moved to tape backups in the last few months...

Anyway, I'll give it three eggs for the benefit of the doubt, though the drop (IF there was one) wouldn't have been more than from the top of the workstation it rests on, a couple of feet.

Top popped open and won't stay shut, so will not waste time trying to warranty it, instead I'll see if either or both of the drives will work independently.

4 out of 5 eggsTwo One Terabyte Drives

Pros: Two 1 Terabyte hard drives in a single casing. Very simple to use with included software applications. Fairly easy to remove drives for use in other computer systems if desired. Was able to insert two previously owned 500 Gig drives and use included software without issue.

Cons: Flimsy USB connector on back. The "Green" power-saving feature causing the drive to go to sleep often, taking several seconds (and short system lockup) to wake up.

Other Thoughts: Please Note: The use of other hard drives is not recommended by, nor detailed in any of the information that accompanied this product. Such modifications mentioned below were done by me with the understanding this would void my warranty.

I messed with the RAID aspect a bit for a few days and found myself wanting to take advantage of the full 2 Terabytes rather than the 1 Terabyte backup feature offered by default. I used the included software to make it recognized as 2 Terabytes but did not like the fact my computer identified it as a single 2 TB drive. So I removed the drives from the case and ended up installing the drives individually into two external enclosures. If you're interested in having two one Terabyte drives to install individually, then this is a great way to go. I did also find that when I put two identical 500 gig drives into the original enclosure, they worked flawlessly with the RAID software for either a 500 Gig mirrored setup or a one Terabyte single-drive.

3 out of 5 eggsCheap Connections!!

Pros: Lots of space for low cost. Easy setup allowed for my XBMC to get up and running in no time.

Cons: Device came with lose connections (USB and Pwr). Really should have SATA or Firewire, i think... Heard problems with x64 Windows, none here though.

Other Thoughts: With in a month would not stay plugged in. Couldn't RMA it since it was past a month. Have to deal with WD tech support not bad just a hassle, hope i dont lose my data when i switch enclosures.

5 out of 5 eggsGreat bang for the buck

Pros: Excellent mindless RAID 1. It comes configured that way out of the box. Data is safe/secure. Quiet and cool drives. No additional software installation necessary in my case. Just plugged it into an XP SP2 machine without issue and installed basic driver.

Cons: No way to turn off 'power save' feature. Drive goes into standby-mode if there is no activity to it after 10 minutes. Drive wakes up in ~10 seconds from standby-mode.

Other Thoughts: Other connections would be nice, but works as designed and you receive well worth what I paid time and free shipping to boot. Arrived in a couple of days. The blue light I can see being annoying to some as it did bother me a little at first. After a week, I could care less. And as others suggested a piece of tape (Black electrical would be ideal) can block it if you're really that bothered by it. The additional software didn't interest me at first. Later on, I decided to install the WD Drive Manager software, but nothing else. I like that it provides the amount of space used, temperature condition, and RAID type/status in a 'sys tray' icon. I wanted a simple and effective backup solution with no hassel. This is it.

4 out of 5 eggsSolid product

Pros: Capacity is ample for my needs
USB 2.0 transfer speeds are acceptable for my level of use
Works perfectly with Apple's Time Machine software
Conserves electricity

Cons: As others have stated, energy saving firmware is sleep happy.
All drives can fail, as one of mine did about a month after receiving unit.
Capacity LEDs on the front are nifty, but I would rather have LED drive health indicators instead.

Other Thoughts: For reliable, affordable backups I wanted a trustworthy RAID 1 mirror setup that I could use for Time Machine backups. I've used WD drives almost exclusively for over 20 years, and I've generally had great success with them. Unfortunately, after just over a month of very light use, one of the two drives in the mirror died. Initially, WD stated that they could not replace only one drive in the array. The support rep said that they would have to replace the entire My Book. What's the point of a RAID array if the whole thing has to be swapped out? After working with their support rep, I was able to get them to agree to sending just a replacement 1TB GreenPower drive.
Someday, I hope that residential bandwidth in my area will increase to the point that I can perform Time Machine backups to AWS S3 or Mozy. Until then, we all have to deal with the potential failings of mechanical and solid-state hard drives.

5 out of 5 eggsCheap, reliable, redundant storage

Pros: I bought this drive to serve as my MP3 and FLAC backup drive. I was tired of having all my music living on a single drive that could die suddenly, losing years of collecting and hundreds of hours of re-tagging, and all the time spent ripping the original CDs I owned, too.

The best things about the drive are that it's VERY quiet for 2 spinning disks (my fiancees single drive WD is much louder than this), it's fairly compact for what it is, and it simply works. A small tray icon lets me quickly see the space filled and the drive health, but besides that the redundancy is completely transparent and requires no work or monitoring on my part. While the data on the drive can still be hosed with some kind of filetable issue, it's great peace of mind to know that a single drive failure won't destroy my music. As a huge plus, on sale, this drive is a total steal, and even normally priced it's a pretty good deal for the enclosure and built-in RAID.

Cons: Bright blue light on the front is very annoying, I covered this up with electric tape.

4 out of 5 eggsEasy to use - but wish it didn't sleep

Pros: - Obviously, the data security of RAID 0
- Attractive design
- Never gets hot
- Quiet!

Cons: - Can't stop it from going into sleep mode
- Ambiguous power button
- Annoying wall wart power plug

Other Thoughts: The drive goes into sleep mode after 10 minutes. This setting cannot be changed. (I guess it's part of WD's stupid green initiative.) It's frustrating because when I want to access a file, if the drive is in standby, it will take about 12 seconds for the drives to spin up (it sounds like they spin up separately, maybe so they can sync up?). So what I've done is set my Windows 7 slideshow gadget to shuffle pictures off the external HD, and I've set my AIM to write its sign-on/off event logs to the external HD, so those activities generally keep the drive awake by regularly writing data to it.

As for the power button, I'm not really sure what it does. Because you can't power the drive on unless its USB is hooked into a computer, and you can't turn it off while the USB is hooked in. I'd much rather a hard on/off switch like most HDs come with.
