In my IT inventory are many older hard drives- some are IDEs and some are the SATA interface. Many came out of desktop PCs and others from laptops. The ones which can’t be sold or used in computers have been repurposed. I use them for backing up my data on my servers and regular computers. They are kept locked up and off-line in case my computers get infected from ransomware or other malware.
Do you have any unused hard drives laying in a desk or cabinet? They could be part of your archive and backup strategy.
