So let me preface this with I have a fairly robust network infrastructure.I started with spinning disks in mine and eventually switched over to 4tb WD Red SSD's.I have this connected to my network using both 10GbE SFP ports and both 2.5GbE ports, each for availability to different VLAN's. The transfer speeds are amazing, I'm averaging over 900Mbps with this unit.While yes the Menu system can be a little frustrating, once you get used to it, it works! With SSD drives it runs much cooler. I did upgrade the memory to 16Gb and added two NVME drives, one for caching and the other runs an NFS share to my Proxmox Servers and provides high availability for some VM's I run.All in all this is a strong unit, build quality is excellent.The noise albeit can be higher as you crank up the fans. Typical for a 1u piece of gear, those little fans have to work harder. So if you are not putting this in a server cabinet, yer gonna hear it with standard hdd's.I have mine syncing with my Google Cloud storage for redundancy of my Google shared files. So anything I add to the share for Google added locally get synced up to the cloud and vice versa to the NAS.There are a lot of apps available for this device. You can run a media server directly from it such as Plex as an app.I get no stuttering when I'm streaming content from this NAS.All around, I'm loving this device and would strongly recommend it. Bit of a learning curve with config/menus, but like I said, gets easier over time.Price point is pretty good too for a rack mount NAS.Hope this helps some of you with your decision making.Some people have stated issues with slow/poor performance, I'd assume some misconfiguration is more likely the cause. If you are going for 10GbE and high performance you gotta make sure your network is configured to handle it and your workstation as well.Good luck to all those in the hunt!

I picked up two of these to split the NAS workload in my test lab and they're great. Easy to setup as always, no issues configuring...anything. They just work!They are my second and third NASes, respectively. I have an old TS-451+ that will be decommissioned to a backup device, but it's been a workhorse. No issues with QNAP and happy to have a couple more of their devices in my environment.

I bought this because it was inexpensive, supports 10G networking, and for the qumagie photo app.I have two Qnap NAS but they are old and the OS is a version that doesn't support the qumagie app.I bought this used (like new). Only issue is that CPU temps is hoovering at 140F. I had this NAS at 90-99% for about 24 hrs doing indexing and face recognition on 25k of photos and I had no issues with it. Perhaps that's the reason why it was returned?I've upgraded the ram to 32G with two 2T nmve drives (one for caching). The ram upgrade seems to be overkill since it hasn't used over 15% of capacity yet.This is a good buy esp for the value.

This model has an ARM processor. Several of the features that QNAP advertises they do not support on ARM devices. This would not be such a problem except that it is very difficult to find out what is not supported. The main feature that they do not support but never mention in the documentation is the lack of Kubernetes support in Container Station. Container Station also does not support IPv6.In addition I was extremely disappointed with how their app store does such a bad job of distinguishing apps that are part of the advertised feature set and free versus add-on third party purchases.I will say their support was pretty good. They did get back to me within 24 hours to tell me that buried in the release notes for the original version of Container Station that introduced Kerberos support, it says it is not compatible with ARM.The actual hardware also seems pretty good. Because I wanted 10gbit fiber connectivity, multiple NVME disks for cache and 4 drives for RAID it was pretty much my only decent affordable rack-mountable option.

Ok So your Thinking NAS for your home hobby network. This unit has been running in my setup (Ubiquity) for about 2 months now. I have 4 X 10tb WD Red's as the primary storage and one 1tb M.2 for the Cash. I did upgrade the ram to 32gb (KF426S16IB/32). I have two 10Gb SFP aggregated to my aggreggation switch giving me 20Gb for primary and two 1Gb aggregated to IOT for hardware access to PLEX.The setup process is mostly simple but will require some research for the proper virtual switch setup you need. Streaming movies over WiFi is hard for this unit because of the PLEX app not having the ability to adjust buffer size. Over hard lines internally its not an issue.I run the minecraft server for the kids also, that was simple to set up and appears to work nice. Kids are happy.Transfer speeds for my set up unfortunately dont ever come close to the bandwith I've set up. My limitations is the drives, they appear to simply be slow. But I felt its was better for data safety to have the mechanical drives intead of the digital drives, thats just me.Here's the reason I left 4 starts, its because of the packaging. For the price you pay this unit came in a verry weak box, with tape marked "not to tamper". Mine was.... repackaged, so you can imagine the worst when you open the box to find this unit supported with two peaces of foam and nothing else. No paperwork, no instructions, nothing but a sticker on the wraper. QNAP YOU CAN DO BETTER!

So, I've been using this NAS for a year or so now. Initially, the array would drop every month or so. I worked with the QNAP customer support and they eventually replaced it. Problem is, the same thing happened. After further support, they sent me new drive trays and the NAS has been rock solid since.I would caution anyone prospective buyers to keep QNAP products behind a firewall though. There are a lot of ransomware variants that target QNAP so if you make your NAS accessible from the internet you'll likely get hit.

Let me say there was a small hiccup with my first purchase of this NAS - It was a dud - the Bios either wasn't programmed or was so corrupted that the NAS would not appear on network when directly attached to either 2.5Gbe port. It would not respond thus unable to initialize using QNAP's Qfinder Pro. ItServiceman.com came out and spent two hours trying to get this online! Qfinder located the replacement immediately and following some installation video advice and reading everything carefully I got this up and running on my own. No need for ItServiceman this time! I did easily install two 1TB M.2 NVMEs in RAID-1 and four 10TB HDDs in RAID-5. The NVME slots have a neat little lever locking system so no tiny screws to mess with. The RAM upgrade to 32GB was also simple and the system recognized both as if they were OEM. 32gig is overkill by the way 16Gig will easily do everything you need according to ItServiceman. But I had already bought the 32G. I am very happy with the working unit it did take about a half a day to fully synchronize the RAID-5 configuration with four 10TB HDDs leaving 27.26TB of usable storage space after default setup and installing HBS-3 Hybrid Backup. I personally had some difficulty setting up the Snapshots as I didn't leave them enough room - so the recommended amount of dedicated space is 15- 20%. I was able to create two thin volumes dedicated for Apple Time Machine with the help of QNAPs help links. They are working so it shows that if you read the documentation and I got some Video advice from QNAP-UK videos even an end user can set this up. Sorry ItServiceman I'm saving some money here. Overall Recommended, obviously there could be a quirky unit floating about out there but with Amazon Returns (Yes-Prime Membership) and some patience I now have a great NAS!
