odd redundancy solution

ok so my current set up is
500GB SSD as my C drive

and 2TB HDD as secondary storage. 

I was thinking about getting 2 more 2TB HDD so I can have some redundancy. 

my idea is I put the 2 new HDD in raid 0 and put a 2TB partition and a 500GB partition and put those partitions in raid 1 with the corresponding SSD and HDD. 
is this even possible?

For redundancy I would get another 500GB SSD and Raid 1 with your current SSD. Then just pick up 1 more 2TB drive and Raid 1 that as well. When you talk about redundancy... Raid 0 should never be used.

 

It might be a better project to build a NAS that's not on your computer and just backup critical data to that.

yes, but that is expensive. I would love to have a NAS but I can't afford one.

If redundancy is your goal, RAID 0 is not your friend. If one drive goes down, the entire array goes down.

While I don't see this being impossible, I also don't see much point. You would significantly reduce write performance to the HDD (the system isn't going to say it's done writing until both drives are done writing) and you'll lose read performance. Probably not as much as going down to an HDD, but it won't be at SSD speeds anymore.

I have a blog! And a list of guides I've posted

ok, then I would be better to have the SSD back up to it every so often rather than put them in a raid.
