Which RAID should I select on OS6

Hi All

I have just upgraded from 4.2.X to OS6.51 and everything fine.
I have 6 disk (2x8tb + 4x4tb)
On 4.2.x I was running Xraid2 and that went great during expansion/upgrade and diskfailures every time.

Now, with the new OS6.51 its set to Raid 5.
I have tried to mess around, set to flex-raid, delete volume and changed the Raid, but I dont see the "XRaid-2" anywhere ?
How do I find that ?
OR ... do I have to ?
Will the Raid 5 Set to X-Raid be as safe as the (old) Xraid2 ?

Please advice ?

    On RAIDiator 4.2, you had to Factory Default the NAS to switch between X-RAID and Flex-RAID.
    On OS6, you can simply toggle X-RAID on and off. X-RAID off corresponds to Flex-RAID.

    Yes, and in fact it is the same thing.

      Personally I would go with RAID-6 rather than RAID-5, but with RAID-6 you are limited to the capacity of the fourth largest disk.

       

      RAID-6 is used by X-RAID2 dual-redundancy as opposed to RAID-5 which is used by the default X-RAID2 single-redundancy. If you want to use X-RAID2 dual-redundancy on OS6 you can disable X-RAID, destroy the default volume, create a RAID-6 volume called "data" and re-enable X-RAID.

        At the moment dual redundancy would waste investment in 8 TB drives (giving only a 16 TB volume). Single Redundancy gives 24 TB.
