readynas 104 dual-disk redundancy? Flex Raid and XRaid2
Hi,
I have an old NV+ and was thinking about upgrading but was looking for a dual-disk redundant system.
Sadly the website isn't particularly clear (or I'm not looking at the right pages). Does the new 104 support dual-disk redundancy (Raid 6)?
It seems (http://kb.netgear.com/app/answers/detail/a_id/22808) that flex-raid does raid 6 with at least 4 disk (so the 104 should be able to).
And is it true (http://kb.netgear.com/app/answers/detail/a_id/22802) that XRaid2 only does single disk redundancy?
Any help would be appreciated.
Hava a nice day

- You should be able to use RAID-6 but performance won't be very good. I would recommend getting the RN314, RN316 or RN516.
You should be able to switch to Flex-RAID (i.e. disable X-RAID), delete the volume, create a RAID-6 volume then switch back to X-RAID. - Thanks for the quick reply.
So XRaid should keep the RAID setting, once the readynas is in RAID6 and not go back to RAID5? - Yes
- Perfect. Many thanks!!

Whaaaatt??
unless os6 has changed this, you can't switch from flex-raid to x-raid modes or vice versa without factory defaulting again.
With OS6 you can switch. The existing volume(s) are deleted, but the OS settings, add-ons, etc. are preserved.TeknoJnky wrote: mdgm wrote:

I haven't seen an option to switch w/o deleting volumes though, so I am a bit confused also.- With OS6 you can switch. I've tried it with one volume in my RN516 and it does not delete the volume as far as I could tell.
It did on my RN102, but that was with the first beta firmware.mdgm wrote: With OS6 you can switch.

I have a 6-drive RAID-6 array that I converted to a X-RAID2 array.
- I'm still slightly confused.
Has anyone had success with a 4 disk system and XRaid2 as a Raid6?
And are you sure that afterwards XRaid2 really has dual disk redundancy?
