ChatGPT is especially prone to fudging numbers. 75MB per page is suspect. I think a 300 or 400 dpi 8.5x11 sheet of paper saved as high quality tiff is about 10M

ChatGPT is especially prone to fudging numbers. 75MB per page is suspect. I think a 300 or 400 dpi 8.5x11 sheet of paper saved as high quality tiff is about 10MB IIRC. Not at my computer to verify though. I think you can do a lot better with JXL or a modern format. Price per TB can be as little as 50 cents but you'll want lots of redundancy so it'll be at least 3 times that. I think you could do sufficient amounts of redundancy for $5 or $10 not $20 or $30
