    Western Digital 4TB My Book Thunderbolt Duo Dual-Drive Storage System

    • Written by from Las Vegas

    WOW! For those who are afraid of "cloud" heights, this is the way physical external access capacity drives should be done! It has excellent transfer rate for video, audio and photo files to date! "Plug & Play" into a network is a snap! It also is housed in an attractive package that is easy to display and not give the perception of 'cumbersome'. …More

    Exact Match

    • Written by from Sugar Land

    This drive is exactly what I was looking for. I am using in JBOD configuration, one disk for Time Machine and the other as a back up drive for uncompressed music. The thing that impressed me the most is how quiet it is. The drives are replaceable, can be used in RAID 1 or 0. 2 thumbs up from me. …More

    Nice for bulk storage, user-upgradeable drives are awesome!

    • Written by from West Hartford

    I've owned this product for about a month, and have had no problems with it so far. Overall, it is quiet, easy to use, and looks nice on my desk. More importantly, it offers fast, bulk storage with user-replaceable 3.5" drives! This is the first sub-$1000 Thunderbolt device I've seen with this feature, and adds a lot of value for me.

    Pros:
    User replaceable drives!
    Thunderbolt connectivity.
    Clean look on desk.
    Easy to configure.

    Cons:
    Expensive for 4TB of storage (probably due to Thunderbolt connectivity)     …More

    Wow!

    • Written by from LONDON

    Bought this to store my iTunes and iPhoto library and running in Raid 0 this drive runs considerably faster than the standard 1TB internal drive on my mid 2011 iMac.
    Installing was as simple as plugging in using WD's Drive Utilities. Given the capacity and speed its hard to think how it could be improved. Totally recommended! An easy five stars.     …More

  • Can one partition the main drive under RAID 1?
    • Asked by Erika S from Arlington
    • 20/12/2012

    2 Answers

    Answer

    Hi Erika,

    After some trial and error I finally did it. Open Disk Utility. You need to first erase the WD Thunderbolt Raid that is preconfigured. Then you go to the first 3TB WDC and create your partitions and name them. You then go to the second 3TB WDC and create the same size partitions and name them. After that, select the first partition and its RAID tab. I then dragged the two like partitions from each of the drives and named it - creating a RAID 1 drive. Then I did the same for the second partition and so forth. The end result is two (or multiple) drives of same size that are RAID1s.

    Hope that helps:)

  • Can 2 daisychained drives, each configured in RAID 0 be combined in a RAID 1 array using Disk Utility?
    • Asked by Steven H
    • 30/09/2012

    1 Answer

    Answer

    You can combine two RAID0 Duo's into a RAID 10 array for redundancy. According to WD, because of the two channel Thunderbolt (not to be confused with two Thunderbolt ports), if you daisy chain two of these in one RAID0 set, you'll see a significant increase in performance. In a single RAID0 Duo, it is writing to both of the internal drives simultaneously, doubling the speed. So if you have two channels, and two Duo's, it makes since that the speed would double again. It is writing to four drives at once, hence 4x the speed -- in theory. …More

  • if we get the 6tb drive assume with dual drives , it really only has 3tb total storage may be a dumb question
    • Asked by Richard R from Norwalk
    • 25/05/2012

    2 Answers

    Answer

    It can be either, you have the option of RAID 0 which gives 6TB or RAID 1 which gives 3TB and the drives are mirrored so protecting against drive failure. Your choice, safety or speed and capacity. I have gone for capacity as I also have a FW800 6TB drive for backup which is set for RAID 1 to allow for any failure of the Thunderbolt drive (I only have the 4TB thunderbolt) Hope this helps. …More
