I sold my QNAP NAS a year ago as QNAP does not have a strong security track record. If anyone is looking for an open source NAS solution, I recommend OpenMediaVault - it runs on Debian Linux and provides a management GUI for managing ZFS pools. I'm currently using a 3 disk setup with WD Red (CMR) drives + SSD cache on ZFS with it and have had a good experience in the past year using it so far. I've had to replace one of the disks due to age and ZFS makes it super simple to replace and resliver disks.
