Unfortunately no one can be told what fun_plug is - you have to see it for yourself.

I have a DNS323 running fonz plug. It's configured in RAID1. As I have replaced this NAS by a larger one, this one is just used as a backup device to rsync certain stuff to. So I no longer need the RAID1, and want to shift to RAID0.
What is the best way to go about this, so I do not have to start from scratch? I know I will lose all data from my disks.

There's only one way to do it - reformat the disks, choose RAID0, and then reinstall fun_plug & reconfigure - and for what it's worth, given the fact that RAID0 on a DNS-323 offers no performance benefit, and doubles the risk of data loss, why even consider it?

Is that a trick question? Because it doubles the storage capacity, compared to raid1.

Indeed. As I said: this is no longer my primary NAS, it is used to keep backups made by rsync. So yes, I don't care about redundancy in this case.

No trick at all - compared to RAID1, yes, RAID0 does offer double the storage capacity, at double the risk of data loss - HOWEVER - compared to standard volumes, there is no increase in capacity, and the increased risk of data loss remains.

Oh, OK, that's what you mean. Well, I don't want to buy one new 2TB disk, if I have 2 1TB's in my backup NAS (in most cases backup of my backups). I'm cheap like that.

It's your data - but the way I see it, an unreliable backup is worse than no backup at all - a disk failure with RAID0, you lose it all, a disk failure with standard volumes you lose no more than half, and, depending on how much data you have to backup, two separate volumes allows you to maintain two levels of backup - if you've ever worked with tape, think of grandfather-father-son rotation.
