I have been unable to make any sense of the speed/performance ratings of uSD cards -- esp wrt their selling prices. What appear to be identical products from the same vendor often have different prices. Or, different markings.
Is there a general rule-of-thumb regarding what you should be willing to pay (i.e., what level of performance you should strive for)?
E.g., I recently purchased some 32G cards for my eBook readers with the thought of moving my entire library onto uSD cards and swapping them in/out as needed (I think 32G is the largest size they support). I am assuming performance in this application is insignificant -- read a few KB from the card, wait for user to flip the page (I don't watch movies on ereaders).
In fact, I can't imagine how performance would be of any concern short of trying to display video, regardless of the device (e.g., why would a phone need any particularly advanced level of performance?)
Or, is this just "marketeering" -- gold plated speaker cables, etc.?
