The exFAT is a Microsoft file system that is adjusted for flash drives. It can be supported on Windows XP and in Windows Server 2003, and due to its data structure, it can be used in many cases where there aren’t other feasible solutions.
The Extended File Allocation Table system represents a method that usually people turn to when they have problems with the systems that they normally use. Although the New Technology File System features technical improvements over FAT it may not always represent a solution for the user’s needs, so it can be replaced with the exFAT Linux. The exFat can be also used in case that the standard file system features a file size limit which is unacceptable.
One of the differences that exist between the exFAT Linux and the NTFS is that the exFAT is unable of pre-allocating the disk space for a file only by marking random space as allocated. Furthermore, the exFAT has to run a physical write that must be equal to the size of the file. However, it is supported in a large number of devices such as modern flat panel TVs, portable media players and media centers.
Although they might be different from many points of view, these Microsoft file systems have one thing in common. They feature a storing space which is larger than the Microsoft’s old FAT32 file system capacity. Moreover, while the FAT32 includes a size limit of 4 GB, the exFAT Linux and the NTFS have been created to support 16 EB. Still, the NTFS has more improvements than the exFAT:
• it has an better support for metadata;
• it uses advanced information to deliver a higher performance;
• while the NTFS is supported on Windows versions which are newer than Windows 2000, the exFAT system is supported on Windows versions which are newer than Windows XP SP1;
• it is a more reliable system;
• if it is used on Hard Drives, the NFTS operates faster than the exFAT which incorporates a simple file storage algorithm that runs well only on Soild State Drives;
• it features some practical extensions such as file system journaling and security access control lists.
As we all know, the performance that is delivered by a system depends on the type of data that is stored. The way that the blocks are allocated in the file-system can also decide what type of performance is going to be delivered. Therefore, exFAT features a higher performance for smaller files.
