Yes, nobody should. Still, they do, and I've seen people attempting to use
these in servers and hardware RAIDs (with big failures). Alas, consumer
market is driven by ignorant customers (which are vast majority), hooked
by advertisements, and the attempt of competing vendors to save on
production cost. This is two-fold thing: competition is good, forces to
develop and manufacture better things, and competition is bad, forces
manufacture poorer products as result of attempt to safe on production.
The ugly results of that are: fake RAID chips (LSI, 3ware, Areca _never_
made such), "shared" memory video cards,... you can continue the list.
