Limited use policy is all around, and I've never seen it challenged. Although I'm not a lawyer, so naturally I don't actually follow such news. The most common example is perhaps when you buy any electric device/appliance. They very often say it's only meant to be used for domestic (at home) or equivalent purposes, not professional (industrial, commercial, etc). It's also not uncommon at all to find clauses stating that if abnormal use or poor maintenance is noticed upon item return, the warranty will be void and a service fee will be charged. I recently bought a new coffee maker. It had all of these clauses in the instructions leaflet. I don't think I'd win any court cases if I tried to challenge those specific points if I had clearly broken them. Of couse I'm not saying an SSD manufacturer could forbid something after a person had already bought the thing.
