So I recently found out that I have sh*t my leg... I was about to set up unraid but just before dipping my toes I was told that the parity drive needs to be the same or larger in size, really wish I had done more thorough reseach before recently buying that 10TB HDD hehe...

My planned setup was; 250 GB - SSD (Cache) 1 TB - HDD (Parity) 2 TB - HDD (Pool) 10 TB - HDD (Pool)

So what are my option now that I have messed that up, what would you recommend? To go without parity or is there another way?

Any help is appriciated, I am still quite new to selfhosting/linux :)

UPDATE; I can trade the 10TB for two 4TB disks + the extra. Should I?

250GB - cache
1TB - Pool
2TB - Pool
10TB - Parity

With only 3TB in the pool you're going to be increasing the size of the pool potentially quite quickly depending on if you're ripping DVDs or Blu-Rays to it.

You'll soon need another drive to boost that pool size and I promise, that parity will keep those tears at bay if something happens.
