> Of course don’t go by marketing buzzwords on trash markets like Amazon. Professional means used by people who rely on the product for their profession. Often these are products or brands that laypeople have never heard about before.

That's good advice, but hard to follow. There's a big information deficit there: it's hard to shop for something you've never heard of, perhaps sold in an unusual corner where one of the typical consumer signals apply.

> For example I have the same heavy duty washing machine for 30+ years. Many of my friends went through at least 5 “consumer” washing machines in the same time.

Speed Queen? I think that's an area where the professional grade stuff is a little more accessible. They've got consumer-appropriate models (with the commercial internals) sold in regular appliance shops (though they're not everywhere).

> I wouldn’t know what the equivalent is for USB sticks, don’t really use them. I’m sure you would find a sturdy one with some research. Or you can buy the same trash product many times.

Swissbit is one. They sell industrial-grade memory cards and drives that trade off capacity for reliability. Though a cheap high-capacity one is probably the better trade off for most people.
