what is difference between fat & ntfs

Answer Posted / sumit

FAT (File Allocation Table) and NTFS (New Technology File
System) are both types of file systems on our operating
system. We can choose any of them, but from Windows NT
onwards, NTFS has become more popular. FAT has also got
different versions like FAT12, FAT16 and FAT32, but now
FAT32 is more prevalent of them.

What you will use in your computer will be decided on the
performance, disk size, security, reliability and so on.
You can even use both the file systems on a single
computer. Below I will discuss, some basic differences
between FAT32 file system and NTFS file system, so that you
can get some basic idea of differences between them:

1. As the performance is better in NTFS file system, it is
better to use NTFS file system if your partition is above
400 MB; whereas you should not use FAT32 file system above
400 MB because the performance of FAT32 file system
degrades as the volume increases.

2. You should use FAT32 file system if your partition is
below 400 MB, because if you use NTFS file system, the
overhead of using it will be more.

3. Maximum size of partition that you can make using FAT32
file system is 2 TB (terabytes); whereas there is not such
limitation as to now in NTFS file system.

4. Maximum file size in FAT32 file system is 2 GB
(gigabytes); whereas maximum file size in NTFS file system
is 16 TB (terabytes).

5. There is no file encryption built into NTFS file system,
so anyone can access your files using low level
programming. Whereas, in FAT32 file system file encryption
is there.

6. There is no way of formatting a floppy disk in NTFS file
system because of the overhead involved in running the file
system, but there is no such problem in FAT32 file system.

7. NTFS file system supports the all the POSIX requirement;
whereas FAT32 does not support them.

8. FAT32 file system is generally is used on Windows 95,
Windows 98, Linux and other such previous operating
systems; whereas in modern operating systems like Windows
NT, Windows XP, Windows Vista etc., NTFS file system is
more prevalent. Although you can still use FAT32 file
system on them, but performance will surely degrade.

9. Nowadays, NTFS file system is more widely used because
the storage devices (hard disks) are getting bigger and
bigger; FAT32 is less used nowadays.

So, from the above differences we can see that NTFS file
system is the file system of new world and will be more
widely used as our hard disks will become bigger and bigger!
