Same, everything we have purchased from them has been high quality.

To add simple storage you could go with something like this: https://www.amazon.com.au/dp/B0BQ6SHNP1?

I was blown away at the cool design (the case and cover are the heatsink, you install it with a thermal paste pad inside - how cool is that?!) and how inexpensive 1TB m2 cards are now.

If you want expandable storage, then maybe a NAS?

Husband set up one a year or so ago and it has been really cool. Easy to back up and access anything on it.
