I'm a music lover and like to carry my entire music collection around with me everywhere I go. That being said it takes up A LOT of space, enough to fill a 64gb memory card on its own (a lot of the files are FLAC format.) I was a little hesitant to buy the 128gb card when it came out recently because with the 64gb cards the first batch were pretty much defective with resulted in a recall. Me, learning of the recall after looking up the issues I was having had to return the card I bought. SanDisk took the 64gb card back without hesitation and was actually prepared to do it without the serial number (since I couldn't open my phone at the time because the case is screwed on.)Note to everyone:Quite a few applications don't fully support NTFS or newer file system formats such as exFAT. To use your SD card without issues you have to format it to FAT32 which IS possible even though its over 32GB. Use the &#34;Fat32Format&#34; tool made by Ridgecrop Consultants, there's a GUI (Graphical User Interface) version available for those unfamiliar with using the command line.------After receiving my new card I formatted it to fat32 since I use a lot of applications that aren't the norm and it's easier to use an older file system that is compatible with everything made after 1996. The transfer of files and swapping of cards was seamless, my computer's micro-sd card reader recognized it without trouble as well as my phone. So far everything is good and there's been no hiccups. Even Google Play has been crashing less when trying to browse my music collection.
