You forgot that the no-name company has a million dollars invested in manufacturing equipment and space and some dozens of qualified workers and circuit RD professionals and contracts to purchase bulk parts at cost you can't believe etc. Sure, you can go out and spend $5-$10 bucks on a USB card reader.but wouldn't it be cool to make your own mini 'solid state drive'?
So how is it a no-name company in China can make a $5 USB stick no larger than the USB connector itself? How are they pulling it off? Why is it you can't make a DIY thumb drive? There has to be a way, not because it's better than a SanDisk or a Cruiser, etc.but because we can!!
