Data mgmt for Passive Acoustic Monitoring best practices?

Hello!

I'm running a small passive acoustic monitoring project for terrestrial species, using audiomoths and swifts. How do people and organizations manage the ballooning datasets of .wav/flac files? Should I be retaining lossless versions of all my recordings for posterity?

I currently have two 10TB external hard drives (ext hdd). My workstation internal storage is small (250gb). Right now I copy .wav files from the memory cards to ext hdd #1, back it up as a .flac  to ext hdd #2, and run analyses directly from ext hdd #1. I am concerned that I will eventually wreck ext hdd #1 with lots of reads and writes. I am already approaching the point where I need a third ext hdd to hold more data, but my organization is discouraging ext hdd use for several understandable reasons. I would like to be able to keep all the data I collect so other researchers can use it in the future, and host any derived detection data I make on a public repository. Is this what other people are doing?

Thanks!
