Synology’s 2025 refresh brought the DS225+ and DS425+ with the familiar Intel Celeron J4125, but it also quietly removed the kernel graphics driver support that Plex, Jellyfin, and Emby use for hardware transcoding of H.264 and HEVC. This guide explains what changed, why it matters for real-world streaming, and how you can restore GPU-accelerated transcoding on these models using an unofficial SSH method shared by the community. If you rely on your NAS to reshape 4K or high bitrate files for phones, tablets, hotel TVs, or limited connections, this walkthrough will help you get that efficiency back.
The hardware has nothing to do with the ZFS version, like I said, if you are unhappy with it, change the OS (you can’t on most of the Synology hardware btw). Mine runs silent and got 0 issues with ZFS, it is a TS-464.
Yeah but the QuTS OS of QNAP is in this case. It is not as straight forward to install a other OS on the thing. Specially a NAS OS like TrueNAS scale. having to enable dev mode on truenas and compile a custom driver for the fans to work is not as straight forward for most people. it is not just the ZFS implementation that’s bad also their whole OS it self is.
I literally don’t understand your issue with QNAP hardware, it sounds like your issue is TrueNAS, the only thing I did to change the OS from QuTS to OMV was install an NVME drive and select an USB drive with new OS at the boot menu. No drivers, no dev mode, no nothing.
The cheapest option at TrueNAS is +1100$, I’m not paying that when my minimum requirements were a low TDP CPU with HW encoding and a chasis with 4 disks.
I didn’t say the hardware was bad. The software is. But the issue with the hardware at least for some of those systems is the fan controller.
