In theory I see it as a nice feature to give users the option for a Raid5. But only three disks? That's the bare minimum to get a Raid5. But seeing two LAN ports is nice. If you could team them together you would have a nice redundancy. But please, if you own one of those, keep them updated! Why? Because: https://www.cvedetails.com/vulnerability-list/vendor_id-10080/Qnap.html or: https://safeandsavvy.f-secure.com/2017/04/12/new-nas-vulnerabilities-are-pretty-much-as-bad-as-they-get/ :D

Hilbert I think there's a digit missing from the line: "0% of QNAP NAS users prefer using RAID 5 arrays to benefit from optimized storage capacity, higher performance, and data protection." Either that or QNAP has lost the plot making this product 😀

Yeah that's 30% 😉
