5 out of 5 eggsExcellent warranty

Pros: I am using one of those on a mac mini in a RAID 1 configuration (mirror) for over two years.

I had the most pleasant experience with WD when one of the drives failed.

The drive was replaced by WD under the 5-year warranty (!!!!) without any kind of fuss.

Kudos to WD. That's how you build customer loyalty!

Cons: I only had to pay to ship the failed drive back. The experience would have been 5-star if they had included pre-paid shipping, but that's a very small gripe.

Other Thoughts: Too bad they cancelled the upgrade program in Canada.

2 out of 5 eggsdrive failure

Pros: Was awesome for the first year have it plugged into router for whole house network use convince.

Cons: Drives fail just after two years not worth the money.

2 out of 5 eggsNot just slow--really FREAKIN' slow

Pros: Simplified Raid, Firewire and eSATA, reliable

Cons: Slower than a crippled snail trapped in a tarpit.
Generates heat even when sitting idle.

Other Thoughts: I have owned this for about a year now and use it to back up movie and music files. I use it on with a Mac Mini and connect via firewire. Usually speed is not an issue with me, but this thing is beyond slow. Right now I am backing up 1.57 TB of files...and it has been running for 24 hours. Worse, the copy window states that it still has 178 hours to go!! That works out to about 2 MB/sec.

Also, for what it's worth, the drives MUST be used in RAID 0 or RAID 1 configuration...you cannot treat this as a pair of 2GB drives should that ever be your desire.

I will keep using it, but it is unlikely that I will buy another one.

Manufacturer Response:

We appreciate your feedback and apologize for any inconvenience you may have experienced with the My Book Studio II, as this is not the typical experience with the product. 2MB/s is not the common transfer rate obtained through the USB interface on any of our products. We would recommend you to use another USB cable and verify the transfer speed achieved. Our technical support can help you should you need assistance getting a replacement cable. The RAID configurations the My Book Studio II can use are RAID 0 for extra performance and RAID 1 for data protection. We are here to support our products, and should you have any further concerns or issues, please do not hesitate to contact us at 1 (800) 275-4932, or via our support website at: http://support.wdc.com/rs/. Please indicate within the online case creation or with the first support agent you speak with, that you are responding to a Newegg review, so we route you and your information to the correct team members.

4 out of 5 eggsThe Real Facts

Pros: *Size is better than I thought (my opinion I guess, others claim too big)
*No Fans (Really! no fans, all convection cooling)
*Lots of different connections (Firewire/USB/eSata)
*Good packaging (is that a pro?)
*Can do "hardware" mirror (no WD software needed on final install)
*Takes 12V DC at 3A using normal barrel DC connector (So you could replace adapter easily)
*Contrary to other reviews the RAID function DOES work (once set via USB using WD software) on eSata with no additional software needed once set.

Cons: *No eSata Cable included in box (I got those wonderful eSata SIIG cables from newegg anyway...get them...really...get them)

*eSata Speed != drives speeds (Tests show I BARELY get 40MB/s with the WD unit on eSata. I have done at least 60MB/s with this eSata card so I know it can do at least that)

*Has trouble switching between USB/Firewire and eSata connections (Detection)

*Wall Wart AC Adapter is HUGE...not kidding...very long...really strange

*Manual claims that IF there is ever a drive failure (not sure without the WD software how I would find it but...) that after replacing the failed drive the unit will DISCONNECT itself from ALL PCs until the FULL clone of the array is done. This means you may NOT use the unit while it is rebuilding. Really odd but I can live with it

Other Thoughts: OK, I just got this today and after reading reviews the first thing I did was:

1. Get junk PC (win7 x64) to run WD software on
2. plugged in the unit via USB
3. Switched RAID mode to RAID 1 (Mirror)
4. Attempt to upgrade firmware (received error which looks like the firmware is already the latest version)
5. Unplugged USB and plugged in eSata
6. Fiddle....

At the first the drive didn't really want to detect consistently. Looks like you cannot really just unplug the connections and go straight to or from eSata. I have to do a do a full power cycle (on the drive) to do have the drive correctly find the startup command being sent by my eSata card.

Also I have found that the drive instantly disappears if I try to do NTFS formatting with large block sizes (like 4k). Defaults sizes seems fine.

This is for my OSX SL Mac Pro (2009 8-core) so I went ahead and placed it there on a Sonnet Tech PCIe card. Detected perfectly, so far it's copying my old TM drive with no hiccu

Pros: great speed. very quiet. love the power saver mode.

Cons: a tad on the big side...

Other Thoughts: the drive works great. once after a forced crash, somehow the 1394b port on my mac got wedged, and i had to reset the PRAM but after that the drive has worked fine with out any further problems.

3 out of 5 eggsVery Skeptical User

Pros: Large with variety of interfaces

Cons: I have a pile of dead dual drive external WD drives. They run for a while then they just stop responding, even to the WD Raid application. I don't own one of these, but I am unwilling to invest in yet another expensive drive. The idea of two drives in mirrored mode sounds good, but the dual drives didn't help these stay viable. I guess we will have to see how these perform for brave adopters.
