[I bought this via a friend, to make use of Prime shipping.]I was looking for a cheap but good sd card for my (second) Raspberry Pi 3. Although this card had less reviews, a few mention the Pi 3 specifically, and Kingston is a good brand, so i gave it a shot.First things first, i learned the hard way that some cards are impostors. Well, more likely when purchased from other sellers, as happened to me once when i purchased from Amazon Warehouse. (Which every other time gave me excellent deals on good items. They gave me a refund immediately on report of the bad card.) So, on my mac mini, i ran f3, and here are the results:<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< ./f3write /Volumes/NO NAME/Free space: 28.90 GBCreating file 1.h2w ... OK!Creating file 2.h2w ...
