exFAT Ready NAS
Speeds Up Large Media File Transfer
exFAT is a file system developed by Microsoft® that is optimized for providing fast and high-capacity flash memory (such as SD cards or USB devices). With high-resolution media (such as 4K) now in our everyday lives, QNAP now provides an official exFAT driver that provides compatibility for exFAT-based devices with QNAP NAS.
exFAT – the Next-generation File System
Photographers, videographers, and other creators often run into the limits of conventional FAT32-based storage. With the potential of 4K video files to exceed hundreds of gigabytes, FAT32’s 4GB single file limit makes it ill-suited for high-resolution media files. With exFAT supporting files up to 16EB, you don’t need to break files into multiple smaller ones, eliminating the risk of file loss and minimizing waiting times when transferring larger files from the USB drives/SD cards to NAS.
