s3rialthrill3r: Relatively speaking, I'm sure. The 20TB ones aren't exactly where I want them to be price-wise.
Yeah, the 20 TBs are still too new to be the best option, TB / [currency]. The 16 TBs are getting there, though.
I currently got one Exos X20, one X18 and a X16, plus a duo of the older Enterprise Capacity 10 TB and one 8 TB. Everything just running in JBOD. Plus a 250 GB SATA SSD for the OS, and a 1 TB Corsair MP600 NVMe as my 10 Gbit network upload "cache". And an APC CS-500 UPS for power loss protection (which is what killed the 10 TB I had to replace). Case is a Fractal Design R6. Using regular Windows 10 Pro (don't need server OS features for my in-house use case).
In hindsight, when I replaced one of the 10 TBs recently, I should have bought 2x 16 TB instead of the one 20 TB. Platter density is getting dangerously close to its limit now, regarding seek and read errors, and ultimately data degradation.
So I likely won't be getting any more 20 TBs. I find the risk of a LOT of data loss to be too great.
