QNAP TS-h973AX-8G 9 Bay Desktop Hybrid Storage NAS Enclosure - 8 GB RAM, AMD Ryzen Quad-Core, 2.2 GHz Processor - Supports U.2 NVMe SSD and 10GbE/2.5GbE Connectivity

I use this qnap for plex I have to upgrade the Memory to 32gb of ram for more than 5 Users at the same time on 4k movie for 1080p movie you just need 16gb of ram am happy With this qnap

I have been using Synology for the best part of a decade, with an occasional QNAP sprinkled in, so had a preference for Synology but believed the two were similar enough to give QNAP a try.The specs I was looking for were not available in a Synology for anywhere near the price point of this QNAP; 9 bays, U.2/M.2 capability, decent Zen CPU, ZFS with the QuTS Hero OS option, native 2.5/10Gbit networking, et-al..I don't want to give this item a 1-star review since the hardware itself in my opinion is excellent, but when the software is buggy, and support is abysmal, that is what locks this score to 1 star for me. It doesn't matter how good the hardware is if you're putting data at risk because of half-baked updates, and ineffective, extremely slow responding support.At this time of writing, the QTS 5.0 OS has been out for 2 months, and has had 8 releases, most of which have been pulled shortly after release. It appears the QA process has been offloaded to the users. Reading the individuals trying to help each other in the absence of effective support in the r/qnap forum, and reviews on TrustPilot, this looks to be the same for every major release.I have personally lost data, have been told the LUN import/export isn't supported between QTS and QuTS, despite the documentation reaffirming that exports are portable to 'any QNAP'. I Have replied to support pointing this out and suggested they change their wording, to have been met with silence.Have raised 3 support tickets, two of which I've had to solve myself, the third I've had a single reply over a day ago asking 'is this related to another ticket', it was not, and (I think) that is clear if someone actually read the ticket. Since replying back within 20 minutes, it has been another day without an update, and that's only the initial response to the ticket, no investigation or logs have been looked at yet..The TrustPilot review score of 1.7 echoes these statements.So to anyone reading this? Yes, the hardware is well worth the price, and if you're a more advanced user who is going to install their own OS, such as truenas or unraid, then absolutely go for it. But, if you're going to buy this and use the intended QNAP operating system (QTS/QuTS), I would recommend giving QNAP a miss, and look at something like Synology or other similar units, it's just not worth the risk. Their approach to major releases and lacklustre support appear to be a pattern, and not one you want to invest your time or data into.

I purchased this from elsewhere for less. The NAS is great, it gives you many options for storage with 9 bays. I have mine setup with two 1TB SATA SSD's as System drives, five 16TB drives for storage and two 1TB NVMe's for cache storage using a U.2 NVMe caddy. Fitted with 64GB ECC RAM more options for performance and redundancy open up, especially if using QTS Hero OS on the NAS but even with QTS v4 it helps to have more RAM than less.

The unit is great.However, be warned, quite a few of the apps are costly.Some, VERY EXPENSIVE.If I knew before I bought it. I would have had second thoughts.Update:QNAP support is useless.It's the last item I'll by them.Even with the updated memory to 32gb, it still complains its low on memory.
