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