With 128 GB you can store a good amount of data. I set mine up specifically for a MacBook Pro and it works as expected. (no exfat for me) No fuss, no fuss - I also have a 128GB Sandisk memory card that's about 1/4 the size of this one. Even though I was cool, I was constantly panicking about losing it. It's a bit bigger, but not overly intrusive. Due to its size, it is difficult to lose. I transferred about 100GB to the Topsel memory card - it got pretty hot, but that's to be expected. Nice facility.
