If buying products manufactured by your own countrymen in order to help your own neighbors feed their family is xenophobic nationalism is for fools then maybe we should all be a little foolish.
Anyways, buy whichever drive is cheapest because the performance difference is negligible.
Is someone in south Florida my "neighbor"? Or is someone in Canada my neighbor, they're certainly closer? Heck, helping a Canadian probably does more for Chicago's regional economy than south Florida.
It's all very silly. The world are our neighbors.
Buy the best product- in this case no one is going to argue the Samsung isn't superior. Only a devout nationalist would feel nationalism is a valid point- and as I pointed out it's hardly one rooted in marketplace realities, or one in the best interest of the consumer. Nationalism, along with race are very outdated, 19th century ideas that are increasingly deprecated.
If you want to create an incentive to have an industry-leading product (Samsung 830), then you buy one.
If you want to make it acceptable to offer a second-place, or worse, product- buy something else. Continue along that path, and that's all you'll have left- you just won't realize it because every company realized innovating wasn't worth it any longer.
