Is a hub from a less known brand as good as a Belkin or more high end ones?
Potentially. The more "known" brands are less likely to have an outright 'bad' product - and almost certainly will have better QC.
However, those "known" brands are known due to longevity, reputation & marketing. Two pronged approach that they feel they
can charge more due to longevity & reputation, and
have to charge more on products to offset marketing costs that smaller companies don't necessarily have.
I wouldn't have too many reservations buying a 'cheap' hub as, provided it works & performs to 3.0 speeds (or hits the max expected performance of a drive connected to it), then it just works. Longevity may be a concern, but that's...
