There are no big changes to the UGOS Pro since our review of the NASync DH2300, so we're going to skip past that part and take a look at some new features as well as the headline perk of this new range of devices from Ugreen, namely the AI features. We'd just like to add a quick note here about UGOS and updates, something Ugreen has been offering on a monthly basis to date, with a mix of bigger updates that have added features and smaller updates that have mostly fixed bugs and security issues. Sadly it seems like the company no longer has an up-to-date roadmap for what's coming next, but hopefully they'll update that again after the launch of the iDX-series. At least Ugreen has put our concerns about long-term support in the DXP4800 Pro review somewhat to rest, as the company has been very proactive so far.

The new things

One new thing that neither of the previous two NAS models we've reviewed from Ugreen had, is Thunderbolt. The Intel Core Ultra 7 Processor 255H has support for a pair of Thunderbolt 4 ports and that means speeds of up to 32 Gbps or possibly 40 Gbps, depending on how Intel has wired things up internally. Unfortunately we had no good way of testing the performance of the Thunderbolt interface, as for one there's no built-in test for external drives, as there is for internal drives, nor can you currently add a network share to an external drive. What we did manage to do though, is connect a laptop to the NASync iDX6011 Pro and get Thunderbolt networking going, but as you'll see in the benchmark section, performance seems to need some work, as it was slower than using 10 Gbps Ethernet, when it was working. For some reason, several of our synthetic benchmarks wouldn't play nicely with Thunderbolt networking and refused to work.


As there's support for external GPUs via the OCuLink interface and possibly via Thunderbolt as well, Ugreen provides an NVIDIA toolkit, as well as drivers. The current driver version is 570.181, which appears to be about five or six months old. However, in this case we don't blame Ugreen too much, as providing the latest drivers has most likely not been a priority ahead of the launch. There's no way to get any information about the OCuLink interface, as it's simply an external PCIe interface, so until you plug something in, it's largely invisible.


The final new addition is a feature simply called voice memos, but we have to say that we're somewhat perplexed as to how to use it. It's supposed to offer AI-powered speech-to-text, translation and intelligent speaker recognition, but after a bit of digging, we found out that it requires the use of an unspecified Ugreen recording device, that then backs up the voice recordings to the NAS and then can be put through the software. Reading some previews online, also suggests that there will be a mobile app version that will allow you to use your phone as a recording device, but this wasn't an option at the time of this review. Regardless, this appears to be a pretty niche feature that might appeal to some and the way it ties in with the AI features, as you'll see in the next section of this review.
