Product Description

WD's My Book Studio Edition II dual-drive, quad-interface external storage system for Mac offers optimum performance for creative professionals. Lightning-fast FireWire 800 or eSATA interfaces combined with RAID 0 (striping) yields the speed you need for fast, smooth video and audio editing, rendering complex 3D objects or special effects, and saving huge blocks of data in record time. Set the system to RAID 1 (mirroring) for the peace of mind in knowing that if one drive in this two-drive system ever fails, the system continues to run and your data is safe. Includes automatic data backup software, user-serviceability, a 5-year limited warranty, and works with Apple's Time Machine.

Customer Reviews

They are great drives and very fast.
If you stop working for some time it goes to sleep and then you have to wait 10-20 seconds to wake up.

I know I should probably get another model/brand, but I'll give it one more try.

[Updated this review on 28-Jun-2011]

I have purchased 4 of these Western Digital Studio II external hard drives over the past 18 months (three of them are 4TB, one of them is 6TB), and they are great. The first 3 of these I bought have been chugging along with constant use for more than a year, with nary a hiccup. I just purchased the 6TB model about a week ago, and it looks identical to the 4TB models -- I have high hopes for it as well.

For some context: In the past, I purchased 2 Iomega external drives and 4 LaCie external drives, and ALL of those external drives completely failed after a few months of use, while connected to 3 different computers. Unbelievable! But these Western Digital Studio II drives are a dream. They keep going and going...

These Western Digital Studio II drives have a choice of 4 different interfaces (USB 2.0, FireWire 400, FireWire 800, and eSATA), and I've used them with all of the interfaces. I've also used them on Windows Vista and Windows 7 (both 32-bit and 64-bit), on three different computers. No matter which interface you use, or which version of Windows, they work right out of the box, are immediately recognized by Windows, no drivers needed. No fuss, no bother, no reading the user manual, etc. (You just need to remember to format the drive for Windows; see below.)

Over the past 18 months or so, I have discovered some technical tidbits about using these drives that I wanted to pass along, because it might help someone who is stuck. Most of this information applies to any large external drive that you attach to a Windows computer; this info is not necessarily specific to these Western Digital drives.

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.

Size Name: 2 TB Verified Purchase
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...
