HHUBS Posted August 24, 2021 Share Posted August 24, 2021 Hello, this is my first time posting on this forum and I'm new to the world of NAS. After some research, I want to try unraid OS for 30 days. Base on the docs, it is recommended to start with 1 parity drive and 1 data drive. But in my case, I don't have the budget to do this upfront. Now the question, can I start with only 1 HDD as data drive with no parity or use that 1 HDD as parity with no data drive? Sorry I'm new to this. If I start with 1 data drive with no parity drive, then my data/files are not protected. If I buy larger hdd for parity, say 5 months from now, can I just install this and protect my data without losing data on my data drive? Because I heard that if I change the array, my data will be lost but I think it's referring to the other NAS OS. Thank you. Quote Link to comment

Yes. Parity doesn't have to be any larger than the largest data drive. 1 Quote Link to comment

I'm confuse now. It must be at least equal to the largest data drive - just cannot be smaller. Many people install a larger parity drive as part of future planning so at a later date they can install larger data drives. 1 Quote Link to comment
