From whet I understand thr bigger more expensive UPS have safe shutdown features for your device but are they really that important? Then is my smaller UPS that just provides power and durgr protection useless then? Ftom my understanding, even if without a safe shutdown, as long as data is not beinb transferred at the point of shutdown, it should br fine while idling right?

This UPS has a rated runtime of 1min 10s at 325W !!! Sure it’ll be a little longer if loaded less, but also it’ll get shorter in time as the battery degrades (really quickly with lead-acid batteries!). The whole point of the UPS is to give you time to shutdown safely the system, and this is why it’s usually automatic. If not it’ll be next to useless for unattended systems like a NAS.
