As we will see, exFAT is the best for formatting a small storage device like a USB drive. It combines the efficient, no-nonsense structure of FAT with modern drive capacities, allowing all manner of portable devices to manage their data with minimal overheads. Unfortunately, file formats like NTFS tie up too much of their limited resources without offering performance advantages. While this naturally makes them superior to FAT32, it also makes them too inefficient for portable storage devices.ĭevices like SD cards or USB drives need a simple file system to write to and do not have a large overhead. A New Generation of File Formatsįile systems like the NTFS (New Technology File System) and HFS+ (Hierarchical File System), developed by Microsoft and Apple respectively for their own operating systems, are specialized to ensure the security and reliability of the data stored in the hard drive.

These were critical issues for a hard drive meant to hold system files for an operating system. The format was too vulnerable to malicious code and did little to implement redundancies against data corruption. With time, however, the FAT standard started showing its age.
