NTFS has over fat32 the following :
- supports files bigger then 4GB and capacity over 2TB
- is a journaling file system where changes to files are logged to a jurnal before there are mode ( good in case of a power loss while writing, it wont need to scan all disk)
- support file permissions with user ID, read only etc
Advantages of FAT32 is that no journaling means less writes to the disk so longer life, no file permissions that cause problems when moving the media from one device to another
Allocation unit while formatting :
- smaller size better for space efficiency - if you have many small size files. Ex a 10kb file will need 5 2kb blocks if you chose 2kb allocation unit and when reading will require 5 blocks to be read.
- bigger size for better performance - it will read the data faster, but it will waste space on smaller files - but unnoticeable on larger size disks.
