FAT32 is a 32-bit version of FAT file system using smaller clusters and results in efficient storage capacity. What is the maximum drive size supported?

The correct answer is B. 2 terabytes. FAT32 uses 32-bit cluster addressing. When paired with the standard 512-byte sector size, it supports a maximum volume size of 2 terabytes (2 TB). Although FAT32 uses 32-bit entries, 4 of those bits are reserved, leaving 28 usable bits for addressing clusters. This results in a…

Explanation

FAT32 uses 32-bit cluster addressing. When paired with the standard 512-byte sector size, it supports a maximum volume size of 2 terabytes (2 TB). Although FAT32 uses 32-bit entries, 4 of those bits are reserved, leaving 28 usable bits for addressing clusters. This results in a theoretical maximum of ~268 million clusters, and with a maximum cluster size of 32 KB, the practical ceiling is 2 TB per volume. Drives larger than 2 TB require file systems such as NTFS, exFAT, or ext4.
