Hello there!

Suicide bombers may not wear backpack very often, but when they do, they wear it to the end of their lives

Ten years is a long time. In ten years 4Tb storage will be less than a crappy thumb drive.

For reliant storage I personally would get two hdd for a price of one ssd, slap a software raid1 with ext4 on them and forget about them until the mdadm alerts
