[Hampshire] Keeping My Hard Drives Safe

Hello everyone. Long time stalker first time poster.

Over the years I have acquired a collection of hard drives which I use for
making backups of important and valuable data (i.e family photos, videos).
My question is what do you guys recommend I do / use to keep my hard drives
safe and secure from things like theft, fire, etc? They are just normal IDE
/ SATA hard drives.

Thanks,
Jack
