User-selectable RAID or JBOD modes. When set to RAID 0 (striping), My Book Thunderbolt Duo offers the performance you need when designing or editing graphics-intensive media files. When set to RAID 1 (mirroring), this drive provides double-safe data protection by automatically generating a duplicate copy of your data. Set to JBOD ('Just a Bunch of Disks') to use as two individual drives and select between HFS+J or ExFAT per disk. Ideal for running Windows OS on a Mac.

Daisy-chain up to six drives or devices to create, edit, render, and save your creative endeavors without hesitation. Multitask at high speeds, enjoying workflow efficiency and productivity with the speed and flexibility of dual Thunderbolt ports.

Took quite a while to finally choose this WD 4TB drive for my iMac - as there are so many different combinations to choose from on the market. At the time of choosing the WD there was only one other review, which prompted me to submit my own as I do take this into consideration when making a purchase especially on items that a few hundred pounds. I am pleased that I chose a Thunderbolt drive. Transferring files (cable is included) is very fast. The size is smaller than I expected. And when running is quiet. I have this running time machine and I don't even notice when it does a scheduled back-up. I have had this a couple of months now and so far I am very pleased.

Excellent hardware and comes with WD Green HDs which are extremely quiet. Although WD have updated their Raid software for the Mac, the Mac Disk Utility does pretty much the same thing and comes without any software issues re Maverick or any other OS updates.

This is awesome! I currently have mine connected to a new late 2014 (HASWELL) Mac Mini i7 and daisy chaining on to my Dell U2412M Monitor running full resolution. I have the WD Greens in mine not the WD RED and even better i got mine for £217 from Amazon instead of there now current £355!
So, setting up is pretty easy, one thing to note is on the Mac you need to unmount the WD tool (which has probably appeared on your desktop) if you want to change it from a JBOD to a RAID system, it will continually error out until you do this.
I'm running mine in RAID and it serves as my replacement NAS, with the Mac running as a media/VM server amongst other things.

Using BlackMagic I am getting Write speeds of 109.3MB/s and Read speeds of 111.4MB/s across the thunderbolt connection (In RAID Mod not JBOD). It hosts a multitude of varying VM's/itunes library/movies etc and i haven't as yet had any issues with this, with no lagging or errors. The actual unit is near silent which is awesome! You can just about hear the disks if you get close and everything else is silent in the room.

Nice things about this are even though it has no power button, it will shut down like your mac, so if the mac goes to sleep, the book will go to sleep, if you shut the mac off it will shut the book down! daisy chaining it to my Dell monitor also works a treat, i will hopefully be getting one of the faster (WD Red) ones soon and having more diary chaining from it as well!

Overall i can highly recommend it, the more expensive one now is the WD RED one, (Which I would recommend over the Greens), i can't wait to order my next one!

Its great, does the job and is quiet. The WD disc management software is useless as it does not work under Mavericks or Yosemite. Just use Apples Disc management utility. But unless you want to change the format of the disc, you don't need to bother about this. Just plug it in to your Apple, select Time Machine, then select this disc, set up how often you want to backup and then forget about it until you need to restore a file, its simple as that. Its difficult to judge how fast it is as I only use it for back-up, which takes place in the background.
