hi

I'd like to install live USB system.
Which file system is faster FAT16 or FAT32, after installing and booting from USB stick?
What are advantages and disadvantages?

Hi Chris,

FAT32 uses space effectively resulting in efficient use of the disk space.
It also overcomes the 2GB limit with FAT16. There may not be much of a
significant performance benefit of FAT32 when compared to FAT16.

Hope this helps.

It was installed on linux debian using live-helper:

LH_BINARY_FILESYSTEM="fat16"

or

LH_BINARY_FILESYSTEM="fat32"

Hi Chris,

It does not matter that as much basically. The size of the File Allocation table entry .

Eg Fat 16 used in small disks basically ( < 512 MB), the size = 16 , so it the total number of files or entries possible = 2^16 = 65,536 entries . So max file size possible := cluster_size * 65,536 .

But in Fat32 it theoretically becomes
max file size possible := cluster_size * 2 ^32.

But implementation wise fat16 and fat32 are more or else the same. There should not be much difference in performance other than the max file size it can address.

You can read the FAT specification to gain more knowledge.
