UGREEN NAS DXP4800 Plus 4ベイNAS、Intel Pentium Gold 8505 5コアCPU。 | 8GB DDR5 RAM、128G SSD内蔵、10GbE×1、2.5GbE×1、M.2 NVMeスロット×2、4K HDMI、デスクトップネットワーク接続ストレージ(ディスクレス)。

初めてのファイルサーバーでしたが、導入は非常に簡単でした。 win / Mac / iPhoneからもアプリで軽快に動いていますし、win とはLANで直結して軽快にバックアップできています。（HDD→HDDで100-160MB/s程度 FastCopyを使用して2.5TBのバックアップに4時間程度） おかげで動画編集のストレージ環境の不安が払拭できました。 余っていた2.5HDDも積んでみましたが、少しネジ位置を変えたり、付属のネジで固定（短いプラスドライバーも同梱されています）すれば無事使えました。 こちらは家族用の共有フォルダとして使用していこうと思います。 独自のOSを積んでおり、PC環境からブラウザ経由で見ると仮想PCの様なウィンドウが開きます。 写真や動画のバックアップ、閲覧する機能も普通にアプリの様な形態で、違和感なく操作。 試しに、iPhoneの写真や動画をバックアップしてみましたが、自宅に要る時間だけ、バックグラウンドで動作させ続けたところ、35,000ファイル 1.3TBで3日かかりました。 iCloudからダウンロードしては転送し…みたいなことだったので、かなりしんどそうでしたが、バックアップが完了してみれば、純正アプリくらいの軽快さで動いています。（閲覧しにいくのがめんどくさいのでわざわざここをメインにはしませんが） 更にしまいこんでいた3.5HDDなども積んでみましたが、こちらはしっかりとステータスに『危険』と表示されたので、むしろ安心できました。 速く健全なHDDを沢山積んで、クラウドサービスからの脱却を進めていきたいと思います。 クイックリファレンス的なものだけで、詳しい説明書といったものはありませんでした。 日本サイトはまだクラウドファンディング色の強い、導入ページのみでしたので、LANの直結などはChatGPTに教えてもらってサクっと解決しました。 ChatGPT曰く「すごく良いマシン持ってますよ！」だそうです。 そのうちマイクラサーバーなど仲間内のゲームサーバーも立ててみたいです。

I have had this item for a few months now. Initially, I did some upgrades to the unit with no problems. I upgraded the RAM to 32GB (OWC 32GB (2x16GB) DDR5 4800 PC5-38400 CL40) and installed 4 Seagate Exos X18 16TB Enterprise HDD's in RAID-5 for a massive 48GB storage capacity. I also installed a samsung 990 EVO Plus 1TB NV SSD for caching. I decided to give the UGREEN OS a chance and kept it. So far everything seems very stable and for my use, movies, music and phone backup, this is doing the job really well. I also installed a 22TB external drive to backup my data just in case the NAS failed. All of the built-in software for the backup, moves and music are working very well. The noise level of the unit is very low, especially when the drives go to sleep. There is no noise at all that you can hear from about 5 feet away unless it is reading/writing, then you hear the drives but it is a low rumble that you would expect. The system itself is very easy to setup and once you create the online account, you can access your drive from anywhere. The only tricky part is getting the software installed on the Amazon Firesticks but there are instructions for that. I would definitely say that this is worth the spend. UPDATE: Almost a year in. The unit physically still works flawlessly. I have, however, found a few issues with the two main apps that I use. Theater and Music. First, the apps in general are great but there is a small flaw in teh Theater app where it has trouble detecting movies that have numbers in the beginning or end. The quick fix is the ability to go in and manually detect the movie. The Music app is good as well but has one major flaw that the developers have acknowledged but have not fixed. I have loaded a lot of music in folders (each folder is a CD) and the tracks are numbered. The app will ignore the numbers and only show the songs without it and sort based on that. Any mixed tracks that flow from one track to the next will NOT work since it will sort alphabetically without the numbers in the beginning. Also any tracks that have names that begin with numbers also have them hidden and ignored. I am not sure why this would be a feature, especially when you go to the Folder View tab to view the full name. It makes the app pointless for me. If you are planning on using the NAS for Music or Movies and want to use the UGOS Pro operating system, you should reach out to them to see if this has been resolved. Other than these two issues, the OS itself and the rest of the unit and apps work great.

Built like a tank. Incredible quality inside and out. This is as premium as it gets for the prosumer. It's unbelievable what ugreen offers at the same price point as the competition. Fast, reliable, and built to last. Beautiful unit. The OS is intuitive, polished, and has everything you need to get up and running in a home environment. These units from ugreen are the new standard now. There plastic box competition is going to have to up their game, or fall by the wayside. If you're looking for an Nas, look no further. Ugreen holds the crown.

Definitely a solid NAS. I bought it 6 months ago and used a lot to write a detailed review. Pros: +Good quality hardware. +NVME & HDD storage pool options. +Ultra High speed access/transfers with 10Gbit Ethernet on NVME Storage pools. I think this is the key reason I have chosen this NAS. I can easily reach over 1GBytes/sec. speeds over the 10 GBit network (even can go faster with 2 ethernet link aggregation). I almost stopped using my external NVME drives after having this NAS. (This is really Great!!) Before this NAS I was planning to have Synology DS923+ and 10 Gbps network upgrade. But NVME storage pool is not available unless you don't purchase Synology nvme drives which is even more expensive than MacBook SSD upgrades!!! Besides you cannot find any Synology NVME over 2TB!!! Go to hell Synology!!!! +Silent cooling. +Very fast in general and Very fast startup/shutdown. (Thanks to having a separate NVME drive for operating system) Previously with my old QNAP NAS, it takes ages to boot up so I was never shutting it down and the times I don't it was consuming power for nothing. Now I don't hesitate to Shut down, it boots up less then a minute!! +Compatible with all HDDs I have. +Freedom for using and OS you want. Actually I am using with stock Operation System (UGOS Pro). But I have plans to try TruNAS someday. Cons: -Original Operation System is good, fast and stable, But still needs improvements. For example; manually adjusting the fan speeds, Or conditional adjustments like QNAP has "if X drives goes over 40C increase the fan speed". There few more things that I don't see in the their software, so still there is room for improvement. But still at least faster than QNAP's slow QTS system. -NVME cooling is not efficient. Actually fan doesn't have any effect on SSD cooling. Initially I was using 4TB WD SN850X. Several times I heard the FAN speed up when I was writing on SSD. I checked the system if there is another reason, CPU was cool everything was cool but NVME was over 50 C. And due to fan has no effect on SSD compartment it doesn't cool the SSD down and it blows high for nothing during this write process. So you have to find a cool working SSD with this NAS. But it is kind of hard since it is a NAS and the SSD you choose should have DRAM and TLC Nands. Mostly you can find this combination in higher and drives which are generally get hot. Seagate firecuda 530 and Samsung 990 Pro or any other cooler working SSDs are better options for this NAS. - Similer issue with above SSD compartment is very slim and you cannot use SSDs with original heatsinks. I already had a 8TB WD SN850X (with original heatsink) and I couldn't use it as well. I didn't want to remove the heating cuz I know it will be hell hot. In general finding the perfect SSD for this NAS is really tricky. But there are some 3D print options on the web to make this compartment larger to use heatsink or even to attach another fan for SSD compartment, but in my opinion FAN is unnecessary, if you can install a proper heatsink, I believe all SSD will be fine.

I purchased the UGREEN DXP4800 Plus 4-Bay Desktop NAS because my previous NAS (Drobo 5n2) failed and the manufacturer is no longer in business. What attracted me to the 4800 Plus was the upgradability, especially the RAM. The second factor I considered was price. I have been using the DXP4800 Plus for several months and I have to say I am very, very pleased with it I have a 2.5GPs network and this comes with not only 2.5GPs but also a 10 GPs connection, so belive me when I say file transfers are rapid. In addition, the 4800 Plus has not 1, but 2 slots for M2 drives for file caching purposes (sorry, you can't use the M2 drives as additional storage). The combination of the 4 bays plus the 2 M2 drives (and the 32 GB of RAM I upgraded to over the 8GB it comes with) is really unbeatable for a NAS in this price range. I found setup to be fairly easy, albeit the creation of the share took the better part of a day to configure. The instructions were very clear and the menus were very intuitive. Once I got the share created, I had to migrate multipl TB of data and the machine performed flawlessly. I mainly use this for storing of all of my media for Plex, family photos, movies, etc. and it handles everything I throw with it. The software included to manage the NAS is pretty easy to use, and it has a good variety of apps to enhance your experience. If you've used a NAS before, then you'd see that UGREEN's software functions just like other NAS software, so the learning curve is short. I would remove a 1/2 star for the unintuitive way to have the NAS mapped as a network drive. It took me a few days to figure how to get this accomplished. This is one area Synolgy has UGREEN beat. But once I figured it out (and how to lock the IP address to the 4800 Plus through my internet provider's router), it is now pretty much set and forget. The other big con of this NAS is that for drive sizes of 20TB and above, the number of supported drives is very limited. The final thing I would say is that I like the DXP 4800 Plus so much, I was seriously considering purchasing a second one. I came up with a cheaper, non network option, but I still would buy this again.

I upgraded to this unit coming off a two-bay Synology. I wanted more room for expansion, a bit more headroom on compute capacity, and I was also interested in experimenting with different operating systems. This delivers. Even though it's advertised as four-bay, I would functionally call it a six-bay, because it has two nVME slots, on top of the four hard drive slots. It has relatively good specs (balancing power and energy efficiency, and keeping in mind that most things a NAS does are not compute intensive), has a premium metal case, and noise mostly isn’t an issue (the exception is the dust filter over the fan at the back, it sometimes rattles. I solved that with some double-sided tape to cushion the metal-on-metal contact). Right off the hop, I installed the TrueNAS operating system on this unit, and it was painless. This unit has an HDMI out (an underrated feature) that displays the boot menu when you plug in a bootable USB, and it comes with a writeable SSD drive to which you can install the OS, and keep it hived off from storage. When running TrueNAS, the HDMI out will display the current IP address of the NAS to access its web UI from another device (handy!), and it also has a terminal interface to run various operations with keyboard input. I can't comment on how TrueNAS compares to the UGreen OS (because I never used it), but comparing it with Synology, and having read up on other alternatives like Unraid, my impression is that they're all functionally very similar. Synology has some first-party apps that you won't get anywhere else, but they're not special, there's popular open source alternatives to all of them. Every OS has its library of stock-configured apps (Synology's is relatively small), but to get full utility out of a NAS, you're going to need to figure out how to use Docker (easy if you know what you're doing, immensely confusing *until* you know what you're doing), and every operating system integrates with Docker images in a similar kind of way.
