Convenience
Features Dual 2.5GbE ports accelerates file sharing across teams and devices or gaming storage applications.

PCIe expansion allows for a Multi-Gig 10GbE or 5GbE network card, or a QM2 card to add M.2 NVMe or SATA SSDs for caching.

4K media playback and real-time transcoding; directly watch videos on an HDTV via HDMI 2.0 (4K @60Hz) output.

HBS provides comprehensive backup and data recovery; QuDedup deduplicates the data at the source to reduce storage space usage, bandwidth usage, and backup time.

Cloud storage gateways realize hybrid cloud applications by working with the cache space reserved on NAS to ensure low-latency data access to the cloud.

Hosts multiple virtual machines and containers to execute different applications in one NAS device.

Can use TrueNAS instead of Qnap's OS.

Customer support has bad reputation. Reputation of taking too long to fix security issues or other problems.

The above is just me trying to decide between those units. Already have a DS920+ and looking for a 2nd unit. This time would like a unit with more than 4 bays that being the main reason I have not pulled the triggered yet on the DS920+.

This QNAP seems like a better more future proof investment, with 2.5GbE, and expation bay that could be possible be used for 10GbE, no embedded memory ie if a module fails is an easy fix, has HDMI. On the other hand it doesn't have something equivalent to SHR which means upgrading storage might be more complicated or involve a higher investment. Doesn't have M.2 NVME support which is not a deal breaker.

I like Synology but on paper this QNAP unit looks like a better choice. Will hold to see if an 8 bay deal comes up. Hopefully also a model that has EEC memory.

You can add NVME to QNAP with PCIE card. A big difference you overlooked if you want to use the NAS as security camera NVR is the QNAP has 8+4 license while the Synology only has 2 and the license fee for 10 is more than the cost of the QNAP.

This unit officially supports up to 8GB of ram, but I have 32gb installed in mine. Works great.

I don't remember, however, seeing more than 40% of memory utilization even with Virtualization Station, Container Station, Surveillance Station and many other apps running at the same time, so 16GB should be sufficient as well.
