Setting up RAID6 and RAID0 side-by-side?

Question

Hey guys, I've tried to find an answer for this but wasn't able to myself - if this has been answered before, please don't hesitate to let me RTFM. :)

The question is pretty simple, can RAID6 and RAID0 be run side-by-side? The setup I have in mind...

4x 6TB, 2x 2TB

RAID6=4x6TB=12TB

RAID0=2x2TB=4TB

Any suggestions on how to set this up? System in question is a, Ultra 6 running 6.4.0-T136

Yes, but that is not recommended.
&nbsp;
You would get no more space with that configuration and if either of the disks used by the RAID-0 volume failed all the data on the RAID-0 volume would be lost.
&nbsp;
If you disable X-RAID you can destroy (wipes all data) the volume and create the ones you want.

I'm not a fan of spanning RAID-0 either. &nbsp;As mgdm says, xraid with dual redundancy will give you the same total space in a single 16 TB volume.&nbsp;
&nbsp;
If the 2x2TB drives are already installed and using xraid, then you can expand to 4x6TB+2x2TB dual redundancy. &nbsp;
&nbsp;
If the 4x6TB drives are already installed, then you can't add the 2TB drives to that array. &nbsp;You'd either need to switch to flexraid and &nbsp;create 2 2TB jbod volumes (safer than raid-0), or create a new volume/restore data from backup.

Stephen, I am slightly confused now. Per [url=http://www.netgear.com/images/pdf/WP_XRAID2vsFlexRAID%20_12May14.pdf]this NTGR document[/url], JBOD can only be configured for one disk (even though I understand that the concept of JBOD isn't to have just one drive). I had hoped that document was wrong/misleading, but would have settled with RAID0 instead but as you JBOD would be my favorite.
&nbsp;for your input - I'll try setting up the 4x6TB RAID6 and then&nbsp;the 2x2TB JOBD per your suggestion. Will report back.

You can create up to four volumes with FlexRaid, and I have multiple JBOD volumes two OS6 NAS (and a duo v1). &nbsp;
&nbsp;
JBOD won't work if iyou have a share that is too large to fit on a single drive, and RAID-0 sometimes is a bit faster. &nbsp;But its fragile, so it is very important to maintain backups if you use it.

Thanks guys for your input.&nbsp;At this point all drives are blank.&nbsp;Stephen, I am slightly confused now. Per [url=http://www.netgear.com/images/pdf/WP_XRAID2vsFlexRAID%20_12May14.pdf]this NTGR document[/url], JBOD can only be configured for one disk (even though I understand that the concept of JBOD isn't to have just one drive). I had hoped that document was wrong/misleading, but would have settled with RAID0 instead but as you JBOD would be my favorite.&nbsp;The VOLUME1 (RAID6) is for storage only&nbsp;and I really want that 2 disk failsafe (had 2 disks fail while I was out of town for a few weeks a while back... lost a bunch of data&nbsp;in the process - call me paranoid). The VOLUME2 (RAID0 or preferrably JBOD) is&nbsp;just a storage&nbsp;on the NAS for moving data around,&nbsp;the data in question is backed-up elsewhere - let's call it a TEMP/TRANSFER-VOLUME. So I am not concerned about the missing redundancy on that volume.&nbsp;Again, thanks for your input - I'll try setting up the 4x6TB RAID6 and then&nbsp;the 2x2TB JOBD per your suggestion. Will report back.
