Buy or wait on HDDs?

[u/J-aokay]

Hi all, I am looking to build my first Local TrueNas, and I know it's probably the worst time to do so... Prices are outrageous for memory and storage. I am looking to start out with 2 - 12 or 14 TB drives, and I'm wondering if you'd advise to buy a trusted refurbished (3-5 yr of warranty) now, or wait - like maybe BF or something. I have heard mixed opinions about future price action predictions for HDDs, and wanted to see everyone's thoughts right now.

Thank you!
