QNAP Systems, Inc. - Network Attached Storage (NAS)



How can I use exFAT storage devices with a QNAP NAS?


The exFAT file system is becoming increasingly popular for SD cards and other storage devices because the standard FAT32 file system limitations (such as a 4 GB file size limit) make them insufficient for storing high-resolution media files. By contrast, exFAT supports files and volumes up to 128 PB, making it a great choice for future storage trends in USB drives and SD cards.

Since the QNAP NAS does not natively support exFAT devices, QNAP has collaborated with Microsoft and Paragon Software Group to provide a customized exFAT driver for the QNAP NAS. This driver allows exFAT devices to be used by the NAS, making it possible to back up the device content and to use them with QNAP NAS applications.

With exFAT Driver, the QNAP NAS allows you to quickly share high quality multimedia files.
