RN204: 2x 4TB and 1x 2TB and 1x 3 TB - Not able to use full capacity
OS: 6.4.1 Hello, I spent a lot of hours till now to bring it together without success. The netgear RAID calculator says 8.16 TB in X-Raid and Flex-Raid 5 with my combination of HDDs but I'm n...
That's excactly what I expected how it's working when buying the RN204. But this device is now on it's way back to Amazon and my new QNAP 431+ is initializing the disks right now!
Thanks all for your help!
You should probably post your flexraid extensions in the ideas for storage area.

Having an encryption key on a USB is very useful for the following use case: leaving your data ; you can plug in your USB key & power on your NAS.
If someone steals the NAS with the USB, then they can do an OS reinstall, and copy all my data over the network. So if I leave the key in or near the NAS, then the encryption has no security value. If I hide the key elsewhere, then I need to go physically to the NAS and insert the key before I boot it. If I lose track of that key, then I am in big trouble.
So I personally find the NAS disk encryption to be both inconvenient for me and also to have little security value. If disk encryption disabled the password reset done by the OS reinstall and was stored securely in the flash (similarly to TPM), then it would have value. Though even there, it requires the user to avoid using scheduled USB backup jobs (and to ensure that the backup button on the NAS doesn't copy data to a locally connected USB).
I have already mentioned why multi-layer encrypted volumes are not possible. A separate key would be required for each RAID layer which would have a bigger impact on performance and not be practical. It would also put your data at greater risk.
You can either have multi-layer volumes or use encryption, not both.
You can connect the USB key after the NAS is booted and after a period of time the volume should mount.
You should of course make a backup of the encryption key somewhere in case anything happens to the USB key it is primarily stored on.
Well I do see too many operational headaches with the key, and if you yield to the temptation to just leave it inserted then you lose any benefit. TPM is also a pain, but it is better thought out.

I find this explanation confusing. It seems to me that all RAID layers could be configured to use the same key value. Though I do see that multilayer could hurt performance.
