Air Video Transcoding Performance
After deploying 3 ReadyNAS (1x NVX, 2x Pioneer Pro) for other folks who use it purely as a NAS, I'm playing around with the idea of finally getting one for my own home use and shutting down the RAID5 array in my desktop.
The most important, wife friendly feature, is it must do Air Video transcoding well. Thus, I'm still in a dilemma on whether to go for a ReadyNAS Ultra 4+ or 6+.
My heart tells me that you can never have enough bays. But my more rational brain tells me that its probably time to upgrade the ReadyNAS if I exceed the capacity of 4x 3TB.
Yet, I'm also wonder whether dual redundancy (RAID6) is starting to get more important with our multi-terabyte arrays we maintain these days.
Can anyone give some advice?
Thank you

- in that case i would get the 6+ it uses a dual core pentium cpu with much more horsepower than the atom-cpu used in the 4+
airvideo requires tons of cpu power.
as for dual redundancy. its a must. i had an array die once because of dual disk failure. - Thanks for the advice. By the way, does the ReadyNAS use a ZFS based file system? Or is it still a ext4? Any plans to move to ZFS for additional data integrity protection?
In addition, I remember its not possible to go from single redundancy X-RAID2 array to a dual redundancy X-RAID2 array without having to reformat the entire array. Is that still valid?
If you have an empty slot, you can specify if the next disk is for redundancy or capacity. If all slots are full, then you need to reformat.sdchew wrote: Thanks for the advice.

Of course, redundancy (single or dual) is not a substitute for backup, it just makes recovery from drive failures less painful.StephenB wrote: If you have an empty slot, you can specify if the next disk is for redundancy or capacity. If all slots are full, then you need to reformat.

Sorry if I don't understand. Are you saying that you can start with 2 or 3 disk in X-RAID2 (single redundancy aka RAID5) and upgrade to dual redundancy aka RAID6?
X-RAID2 supports both single and dual redundancy. An X-RAID2 volume can be upgraded to dual redundancy by specifying that the next disk added is for redundancy in FrontView. http://support.netgear.com/app/answers/ ... redundancysdchew wrote: StephenB wrote: If you have an empty slot, you can specify if the next disk is for redundancy or capacity.

Wow. That's fantastic. I'll shoot for the ReadyNAS Ultra 6+ and start off with 2 disk. Once I need more space I'll add another 2 more and go for dual redundancy.
Thanks mate!
