What is your experience?

Out of interest, where are there new drives that cost not much more. When I look at retail in the UK, a 10TB drive is 3 times the cost of these 4-5 year used refurbs. If I could find something 0 -100% more I would likely go new.

Sorry, I should have mentioned that I have 4x 4TB drives that will be brought in (prior array), so this would eventually be 5-6 drives once the drives are in, with room to add more from there. Thank you for the advice, I’ll see if I can get close with 1p new and a backup drives.

Thank you - I have 4 other 4TB drives that would make up the pool and several 2TB drives. I would estimate this to be a pool size starting at 5+ drives and rising, so I wanted to get the parity in place now. But this makes sense, I am considering how to approach a 1 parity situaiton.
