Easiest RAID configuration to recover data if ReadyNAS fails
Hello,
I have a ReadyNAS 104 and am not able to buy another quickly if mine fails someday (the NAS, not the drives), because I live in Brazil and hardware of this type here is prohibitely expensive. Sometimes they cost 10x the value or more. I've not yet put my data into it. A smaller part of my data I don't want to lose and this will be backed up automatically to another RAID 1 set. The rest I can lose but would rather not of course, so I want to have some redundancy.
After researching I see that my best options for the ReadyNAS are RAID 10 or RAID 6 (using 4 x 3TB drives) and, considering the backup for the essential data, both would be OK for me. However, I don't know if either of these options are easily recoverable on a PC (preferably on windows) should the ReadyNAS itself fail.
Another option would be to set it up as 2 RAID 1 arrays. Using this configuration, if the ReadyNAS failed but the drives did not, would I be able to simply install the drives on my PC and use them normally? I've read that the ReadyNAS 104 uses ext4 so in theory that would be possible, right? (using linuxreader from diskinternals, for example, or a linux machine)
If someone could clarify this for me, I would be thankful. I'm sorry if this has already been answered before.

- Yes, I know it still is at level 2. I think it doesn't need to go over to level 3. In fact I almost closed it, as the responses here on the forum were already sufficient to know what to do. The only thing that remained was some help with the error causes.
I did not know beforehand that what the web interface showed as a "rebuild" could be in fact more than one operation (and/or different ones). If I may, I would suggest that you either simplify the user interface feedback, telling that the "rebuild" process is complete only when there are no more operations left, or the exact opposite, that it shows which operation is running. That would avoid confusion. Independently, major operations like these should appear on the web interface logs. I know interfaces need constant improvement and this is not a complaint, only feedback.
Here is the entry (from status.log) for when I attached the last hdd. The nas hanged just after:
[14/10/19 23:02:40 ART] notice:disk:LOGMSG_ADD_DISK Disk Model:ST3000DM001-1CH166 Serial:Z1F2VRCC has been added to Channel '1' of the head unit.
And here is the entry for when I finally rebooted it and the rebuild process got to continue:
[14/10/23 11:50:51 ART] info:system:LOGMSG_READYNASD_ABORTED_NOINFO ReadyNASOS service or process was restarted.
The times are GMT -03:00 (ART). I live in Brazil, Rio, and we're currently in daylight savings time which would be GMT -02:00 but that's not being taken into account. That's another feedback, it would be good if the device had more time options and could recognize automatically or at least have an option to set daylight savings.
About the previous case, yes the password was wrong because I did a factory reset while troubleshooting and forgot to change it. However I promptly changed it back and that's when I've been put on hold for a long time. I was having to leave my pc on for days waiting for access, without responses. Even before the password thing this happened. But that's not what I complained about here, it was about the carelessness of the representatives that didn't even read the case. That's way more basic.
All in all, I'm glad the forum exists and that I have a channel (the amazon email thing was never answered) and someone (you) to which I can pass on constructive feedback. Unfortunately, I had to pass on some rant too, but I think we're on the right track. - Hi, after about 10 days the volume is finally rebuilt. All seems to be well. I'm now copying over the rest of the data. Thanks mdgm and StephenB for the help.
