What RAID settings for NAS build

[PenguinMaster]

Hi all,
 

I am looking into finalizing my TrueNAS Scale build, and I am unsure as to what RAID settings I should use.  This is my first ever NAS build, so I do not have much experience with RAIDs.  The drives that I have for the machine are 6x 4TB WD red NAS "plus" drives.  I also have a 250 GB boot ssd and threw in an nvme cache drive.  At the moment I have one extra cold spare drive.  That would make the total WD red drive count 7.  My plan was to have 5 drives holding data with 1 hot spare.  This NAS will stay at my parents house, and I go away to school for months at a time, so I am unable to get to the NAS to swap in drives all the time in case of a failure.

I would appreciate any suggestions.

I'd just do one 6-drive RAIDz2. That will let any two drives fail before your data is in jeopardy.
