Works seamlessly to plug in old drives and keep moving forward.


Works as expected


-Very efficient -Sleek -Quiet -Powerful

I bought this one to replace another that has seen better days,, and it was as easy as to just insert the old disks and turn it on.... it recognize the disk as synology drives and reconfigure itself.. no problem at all

So easy to setup physically and soft. Enought apps for my needs (Streaming movies) With a WD red in it, was able to stream over Wi-Fi and copyng large files at the same time on it. Silent Robust construction No compatibility limitations compare to... tried to give Ugreen a try and I was really impressed.

much quicker nas than my ds223 have the option to have a warm spare quiet

Decent price for the hardware, sleek design, upgradable RAM, software updates are frequent, drive bays are solid, can control fan speed for the CPU


I was impressed with how the unit was packaged, the included accessories and the unit's design. UGREEN'S attention to details is top notch. I easily installed both of my drives on the unit's HDD rails, slid them in and booted up. I opted for a local configuration only (no UGREEN ID or web access) over LAN. UGOS is minimal but effective: configuration, diagnostics, basic apps, user management, etc. I also installed the UGREEN NAS app on my iPhone, which also works good.

Easy to setup and configure

Good Interface, stable product, great price, good online Video training, easy to setup for basic functions, easy to link to vie home network, TV connections. Quite and good power management.

A convenient, consumer grade drive cage. Definite advantage over in-the-case drive installation. Easy drive swapping. LED lights indicate which drive is in use. Space saving: install 4 3.5" drives in only 3 5.25" drive bays. Fan helps keep drives cool. Inexpensive compared to similar alternatives.



It just works. And in the computer world thats a big win. Runs as fast as a local hard drive.

I have three older hard drives just sitting around, I put them in and have been testing them to see how this unit would react, so far not one hiccup. I'm going to add four Seagate IronWolf Pro ST10000NE0004 10TB 7200 RPM 256MB Cache SATA 6.0Gb/s 3.5" Hard Drives later this week. If all goes well, later I'll add my second TR-004 to my TS-253Be. (according from Qnap Two TR-004 is the max you can add to compatible Qnap Nas systems)
