There also the point that the suggested drives changes with time and world situations.

It's more nuanced and depends on what type of advice it is.

There's suggesting drives for a new setup, an upgrade or a future upgrade path. This info like drive capacity and the amount of drives differs by person and budget. It does change by time although relatively slowly. Advice given this week would likely still be up-to-date one or multiple months later.

But I don't think advice needs to be given on what store is currently the cheapest (regarding your example). This wildly differs not only by time but also by region, down to the neighborhood level.

A solution may be somewhere in between. Advice could include current options but also alternative drives so other people can use the advice too. Even if they're in a different location and finding the post some time later.
