S330 cam and S380 Homebase Question

Hey all, I have 2 eufy security cams outdoors with plans to add 1 more indoor cam in the future.

Few questions, I have the S380 Homebase 3 without any hardrive and I just records events.

How do I record continuously? I am planning to buy an ssd 1tb for the Homebase, will this be enough? I plan to only keep maybe a weeks worth of recording at a time.
