Best 4tb to 8tb drive below 150 euros

I want to start data hoarding ebooks and other educational media, this drive will live off the grid most of the time as my area gets a lot of storms and I've lost a previous setup to a surge (surge protectors did not help). The drive will not see much reading, mainly writing so I was thinking maybe a surveillance drive might be best. I'm looking at around ~2tb of calculated storage I'll be needing so maybe a 4tb or 8tb (if possible with my budget) might be better in order to have some more space for future data needs. What are my best options below 150 euro?
