Am I insane for wanting to upgrade my two parity disks to 22TB from 14TB? What's the size of your parity, if you have one? (lemmy.today)

It used to be that 14TB was the sweet spot for recertified price per TB. After looking around, it seems like it's moved up a bit, at least on ServerPartDeals and goHardDrive, even 22 TBs are floating around $14/TB.

I feel like eventually I could migrate all of my 14TB disks to 22TB and save a lot of heat. Of course, I'd need to upgrade my two parity disks first, which would currently cost around $677 after tax. I'm curious as to what parity sizes everyone else is rocking.

I'm also kind of realizing that this probably doesn't need to be a post, but I'm gunna post it anyway in case someone wants to enable my data hoarding.

Edit: I forgot to mention that I'm strictly considering WD HC drives only.

If I was gonna upgrade from 14 I would go as big as possible so I didn’t have to do it again. Price per terabyte doesn’t matter if you upgrade more than once. Also, array size doesn’t matter if you don’t have a backup server as well

Yeah. I just don't know if I can bite the bullet to spend $300ish more for 4 TB (or technically 2TB when used for parity). Recertified 24TB WD drives are slightly more than $500 on SPD right now, and that's the biggest size (for WD drives)
