Why need to format or convert USB drive to FAT32?
Formatting a USB drive is same as formatting any other drive, so does converting a USB drive between NTFS and FAT32. But have you ever wondered that what the various options mean? Usually, we go with the default setting, but the optimal settings depend on the type of drive and what you are planning to do with it.
1. Is FAT32 or NTFS suitable?
- NTFS reads/writes files larger than 4GB, creates partition larger than 32GB, compresses files and saves disk space, has better space management (less fragmentation), allows more clusters on large drive (less wasted space), adds user permissions to individual files and folders, encrypts file system.
- FAT32 is compatible with virtually all operating system, takes up less space on USB drive, has less disk writing operations (faster and less memory usage).
Due to its nature, FAT32 is suitable for USB drives smaller than 32GB and in an environment where you never need to store files larger than 2 or 4GB. In addition, NTFS is not recommended for USB flash drives, even when they are bigger than 32GB.
2. What’s the best allocation unit size?
Like other hard drive, USB drive is also organized in cluster and the allocation unit size describes the size of a single cluster. Larger cluster leads to more waste or slack space, while smaller cluster means smaller pieces of a file which need longer time to access the file and the USB drive becomes slower. Therefore, if you want to store large files on your USB drive, a large cluster size will make it run faster. But if you want to store small files or run programs off your USB drive, a smaller cluster size will preserve space.
