IMO the only way to perfectly protect yourself against Ransomware Attacks is with CD-Rs, because it's something not even hardware can alter. A skilled take over of the root level of a machine can be encrypting everything and you'd never know it, until the day it denies your access, by deleting an encryption key until you pay up to get it back...you hope.

Or BD-Rs. 50GB on a single dual layer disc. Haven't finished the last spindle I bought, but I assume they're the cheapest per GB by now.

Checking diskprices.com - https://diskprices.com/?locale=us&condition=new,used&disk_ty... - there's a cheaper outlier for DVD-R, then it's 25GB BD-Rs for a bit.

LTO tape can be cheaper, but the cost of the drives has long been an obstacle to dabbling.

Yeah, the prices don't seem to be correct. New 16TB HDD for $200. DVD+R 25x pack for $2, etc. Clicking the links shows different prices on amazon, etc.
