The SanDisk 64GB Dual Drive USB-C Flash Drive was specially built for the Apple MacBook (Early 2015) and is only sold at Apple Stores. The drive's style and design looks great with the MacBook and you don't have to worry about which way to flip your drive to insert into the MacBook, especially in the dark!
The SanDisk 64GB Dual Drive USB-C Flash Drive comes pre-formatted with ExFAT and transferring files between the drive and the Apple MacBook (Early 2015) is fast and smooth given the drive supports USB 3.1 Gen1 (5 Gb/s) link speeds.
