How does the FAT file system work?

Concepts. The file system uses an index table stored on the device to identify chains of data storage areas associated with a file, the File Allocation Table (FAT). The FAT is statically allocated at the time of formatting. The table is a linked list of entries for each cluster, a contiguous area of disk storage.

Which is faster FAT or NTFS?

While file transfer speed and maximum throughput is limited by the slowest link (usually the hard drive interface to the PC like SATA or a network interface like 3G WWAN), NTFS formatted hard drives have tested faster on benchmark tests than FAT32 formatted drives.

What format should a USB be?

In summary, for USB drives, you should use exFAT if you’re in a Windows and Mac environment, and NTFS if you’re only using Windows.

Are there hidden sectors in the FAT file system?

The total number of sectors (as noted in the boot record) can be larger than the number of sectors used by data (clusters × sectors per cluster), FATs (number of FATs × sectors per FAT), the root directory (n/a for FAT32), and hidden sectors including the boot sector: this would result in unused sectors at the end of the volume.

Where does the fat table find the cluster numbers?

The root directory of the disk contains the number of the first cluster of each file in that directory; the operating system can then traverse the FAT table, looking up the cluster number of each successive part of the disk file as a cluster chain until the end of the file is reached.

How is fat allocated in a digital camera?
