File Systems - NTFS FAT FAT32 exFAT | Formatting USB Drives
FILE
SYSTEMS
In windows 7, there are four different file
systems. They are :
- · NTFS
- · FAT
- · FAT32
- · exFAT
If your drive is larger than 32GB, FAT and
FAT32 will not be available. Lets look at the benefits of each file systems.
NTFS
as compared to FAT AND FAT32
·
create partitions larger than
32GB
·
compress files and save disk space.
·
better space management = less
fragmentation.
·
allows more clusters on larger drives
= less wasted space.
·
add user permissions to individual
files and folders (Windows Professional).
·
on-the-fly file encryption using EFS
(Encrypting File System; Windows Professional).
FAT
AND FAT32 COMPARED TO NTFS
·
Compatible with all
operating systems.
·
Takes up less space on USB
drive.
·
Faster and less memory
usage.
exFAT
COMPARED TO FAT AND FAT32
·
Read/write files larger than
4 GB.
·
Creates drive partitions
larger than 32 GB.
·
Better space management.
·
Less fragmentation.
WHICH
IS THE BEST?
Hard drives are
organized in clusters and the allocation unit size describes the size of a
single cluster. The file system records the state of each cluster, i.e. free or
occupied. Hence, larger clusters can lead to more wasted or slack space. With
smaller clusters, however, the drive becomes slower as each file is broken up
into smaller pieces and it takes much longer to draw them all together when the
file is accessed. Hence, larger clusters can lead to more wasted or slack
space. With smaller clusters, however, the drive becomes slower as each file is
broken up into smaller pieces and it takes much longer to draw them all
together when the file is accessed. The
thing you had to keep in mind is that :
Large drive / large files = large
allocation size
If you are having a
low size flashdrive, suppose 500MB, use FAT32 [ 512 bytes ] or FAT [ 32 KB ].
If you are having a large sized flashdrive, suppose 1 TB, use NTFS [ 64 KB ].
WHAT IS VOLUME LABEL?
Volume Label is
just the name that we gives to our drive. You can give any name to your drive.
But your volume label depends upon the filesystem that you are formatting with.
That is given below:
NTFS
·
Supports upto 32 characters.
·
No tabs
·
Uppercase and lowercase support,
display as we enter.
FAT
·
Supports upto 11 characters.
·
No tabs
·
Only uppercase.
·
* ? . , ; : / \ | + = < > [ ], these
characters are not supported.
