This is the easiest, best 4 bay NAS money can buy. You will be up and running in _no_ time. Snapping in four drives of whatever size you choose takes moments. I unwrapped four Toshiba N300 Pro 18TB drives and snapped them into the chassis in about 4 minutes. Connected the NAS to my 2.5GB ports on my lan and had everything up and running and updated with the latest software in under 30 mins. Time to get going is important, but what's more important is how does it run over time?I am 9 weeks into owning the thing and I can tell you this: The software is easy. The system is complete... it's robust... it has features I'll never use--and that's cool if you're looking for a gimungous media server or whatever... I needed it for digital camera RAW storage in a RAID5 scenario. I couldn't say more good things about the product.Managing permissions for users on your LAN is easy, managing storage and basic drive management, etc. is easy. Updating the software routinely as patches and security updates are released is easy. Once upon a time Apple owned "easy" and now iOS has 1138 settings in the general tab and nobody can make it do anything--but this NAS is _easy_. And good. High performance reads and writes near theoretical limits... I literally can not say enough good things about it.Buy it and don't look back. Great value, great performance.

This is my first multi-disk NAS beyond a Raspberri Pi + HDD or a spare laptop running SMB.I'm impressed. The software, though a little cheesy in the package descriptions, is stable and useful. It has the ability to run almost anything in Docker. There are plenty of built-in file sharing protocols. So far, the 8GB of RAM is enough for now and I'm comfortable knowing that can be upgraded. No issues with physically adding and recognizing new disks and managing the array.I'm running a 2.5Gbps home network and this NAS maxes that out bandwidth consistently.I can't quantify is how well it uses the NVME cache. I have a pair of 512GB NVME sticks and it doesn't seem to maximize their capabilities. The disks are a little bit noisy, constantly churning since I'm storing video from one CCTV camera, a little bit of sound insulation in the housing could improve that.

I'm an IT nerd by trade. Normally, i build my own NAS units out of old machines. This time i decided to bite it and just buy a NAS because i'm lazy in my older age.This NAS is easy to set up and get running. has a ton of options for anyone, completely user friendly, easy to upgrade. Flexible thatit supports most x86/x64 based operating systems. you'd just need to upgrade the primary boot drive internally which is a 128gb SSD i believe. Yes you can run windows server on this thing but the default UOS has everything you'd need with less overhead. You can run TrueNAS or UnRaid if you want. tons of videos online showing you what to expect. Note that if you do change / swap the OS, you should either image the default boot drive or pull the drive and replace it then store the original drive in a safe place because ugreen has said you cannot download the stock base OS and restore it.The image i included or attached is the desktop. this is the web interface. the unit has a physical HDMI port and does supply video but i have not used it.Do yourself a favor though. upgrade the ram. the 4 bay unit has 1 ram slot. uses DDR5 i have DDR5 5900 in it, a single 32GB module. The Ram module runs at 1.1v i believe too. it will speed up the transfers and help the unit do what it needs to. Also drop in a pair of 512gb NVME drives and assign them as cache drives. this will boost the overall throughput too. i dropped in a pair of 2tb nvme drives just because i have a couple of them laying around.My unit i stuffed in 4 24TB sata NAS drives. you can use desktop drives but just know this thing will hammer on those drives so desktop drives might suffer in longevity and might prematurely fail. NAS / Enterprise grade drives will last longer and they are built to suffer.I have NAS grade drives in my unit. All are 7200 RPM. i get anywhere from 240MB/s to about 290MB/s transfer speeds this is before i added the cache drives. now i usually get around 730MB/s the unit manages the cache automatically. it will fill the cache drives then shove the data from cache to long term storage as it goes.I have mine configured for RAID 0, BFS file system. it asks you how you want it configured when you plug drives in and do the initial setup.

Has quirks but works well enough. It gets regular updates with some community requested features.I havnt performed a speed test on the 10gbe but it gets to 5gbe easily.

Easy to set up and use. There have been regular updates and improvements since receiving it. Seems reliable. Built on Linux with useful apps. Also offers 2 step authentication
