In general, the larger cluster size you use, the fewer clusters the files will use, and then the faster the files are accessed by OS.

#Ntfs vs fat32 vs exfat Pc#

When the PC writes and reads data, the unit is cluster (not sector), which is composed of 2 n sectors (1, 2, 4, 8, 16, 32, 64, 128, etc.). Volume SizeДЄ disk consists of many sectors whose size is fixed to 512 bytes or 4096 bytes (4 KB) in most cases. When the drive is no more than 4GB, should you use FAT16 or FAT32? Actually, this depends on the cluster size that the two file systems use. volume size is too small and many devices has abandoned the support for it. In this part, I will not talk about FAT12, because its max. Read More FAT16 vs FAT32: Which Should I Use?

16 TB (with 4 KB sectors and 64 KB clusters).

8 TB (with 2 KB sectors and 32 KB clusters).

16 GB (with 256 KB clusters and 2 or 4 KB sectors).

8 GB (with 128 KB clusters and 512-byte, 1 or 2 KB sectors).

256 MB-36 KB (with 65525 clusters and 4 KB sectors).

32 MB-4.5 KB (with 65525 clusters and 512 byte sectors).

To understand FAT12 vs FAT16 vs FAT32 standards, please refer to the following chart: Therefore, when it comes to FAT32 vs FAT, I must explain FAT12 vs FAT16 vs FAT32 actually.

Please note that in Windows 10, the minimum volume size is 8MB and you can't create a FAT8 partition. If you have created a FAT partition, the partition is FAT16 when the volume size is no smaller than 16MB and the partition becomes FAT12 when it is smaller than 16MB. When you create a partition, the FAT32 option only occurs when the partition is no more than 32GB and the FAT option only occurs when the partition is smaller than 4GB. But in Windows 10, FAT only stands for FAT12 and FAT16. In a broad sense, FAT stands for all of them. There are 8-bit FAT, FAT12, FAT16, and FAT32. 8-bit FAT means that it uses 8-bit entries FAT12 means it uses 12-bit entries FAT16 means it uses 16-bit entries and FAT32 means it uses 32-bit entries. When the disk drive capacity increases, the maximum number of clusters must increase as well, and so the number of bits used to identify each cluster has grown. Therefore, you can see, the maximum size of partition/volume that the FAT file system can manage is the product of the maximum number of entries and cluster size (the number of entries determines the number of clusters that the file system can deal with).

And then the system can traverse the FAT, 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. When you need to look for a file, the system will check root directory of the disk that contains the number of the first cluster of each file in that directory. Each entry contains either the number of the next cluster in the file, or else a marker indicating the end of the file, unused disk space, or special reserved areas of the disk. The table is a linked list of entries for each cluster. When you format a partition to FAT file system, an index table (the file allocation table) will be created to identify chains of data storage areas ( clusters) associated with a file in the partition.

Why can't the old FAT file systems manage large disk? To figure out this problem, you should learn how FAT file systems manage disk. The reason why Microsoft releases new FAT file systems is that the old FAT file system can't manage so large a disk as disk drive capacity increases.

Please note that 8-bit FAT, FAT12, FAT16, and FAT32 are variants of the FAT file system. In 1996, FAT32 was released for Windows 95 OSR2 / MS-DOS 7.1.

In 1984, FAT16 was released and in the next few years Microsoft released FAT16 improved versions (FAT16B and FAT16X). It is the first widely used version of the FAT file system. In 1980, FAT12 was released, along with the first version of DOS. The first FAT version is 8-bit FAT released in 1977 and it was only used in some terminal computer systems at that time. And it was later adapted for use on hard disks and other devices. About FAT File SystemДЇAT, short for File Allocation Table, is a file system originally developed in 1977 for use on floppy disks. Therefore, in this article, I only focus on FAT vs FAT32.
