Download Firmware QNAP QTS 4.3.3.0396 build 20171205

QNAP has released an update to version 4.3.3 of the firmware included on various models of its NAS devices. In version 4.3 Among other things, it shows in clear graphs how many resources are used, the performance is automatically optimized based on how the NAS is used and Time Machine backups can now be made via SMB. There is also support for exFAT, for which a separate license must be purchased, and all multimedia apps have been given a makeover. The changelog for this release looks like this:
