Synology DS423chat_bubble_outlineFrom real comments

The most repeated complaint is the lack of built-in 2.5GbE, with several users calling 1Gb Ethernet outdated and a dealbreaker in 2023 and beyond. This pushed multiple buyers toward QNAP or Terramaster instead.

@BryanMack

Just a side note, with link aggregation you can get the network up to 2gbps; still would rather have 2.5 integrated (in each port!) or a 10gbps, but doubling it up to 2 is better than leaving it at 1.\n\nUpgrading from 2gb to 6gb of RAM made a world of difference for me, but I'd still like it to be higher. I've read some people put in a 16gb chip and it works, but for my small plex \"server\" that streams no more than 2 things at once (which is my primary use) this thing has been flawless since implementing link aggregation & adding 4gb or ram.launch

No 2.5Gbe inside, no buy. Synology must get it already, single reason I went for QNAP, no additional level of SW will make more impact in a day to day operation for most setup-once-and-just-use people. It's simply nonsense when the interface bottlenecks even a single HDD speed.launch

2.5 gbe, 4 gb ram, GPU, minimum for every single product Synology makes in 2023+ or no buy for me.launch

Stock RAM is low (2-6GB) and often soldered, with commenters wanting a higher official ceiling and criticizing the lack of meaningful expandability compared to competitors.

@spaxspore

I agree, not to mention 423+ is 120+ or so more expensive and it doesn't have blow you out of the water improvments. Ie - still only 1Gig LAN, 1 solder ram, 1 open max 6GB.. Teramaster as way better specs F4-423 but mine failed and went dead after less than 6 hrs of using - does not post, even with everything pulled. So its going back to Amazon and i went with Synology.launch

It's the lack of networking options and processing power that has prevented me from upgrading from my ds918+launch

I like your video.... but I hate this joke of a NAS. Way to weak and very little upgrade path (well, really, NO upgrade path). It just sucks.launch

The ARM/Intel CPU without GPU is seen as too weak for Plex transcoding or video editing workloads, with one user calling it 'a potato' only good as backup.

@iam_nick

Integrated graphics in DS423+ I think not suitable for people editing content on the NAS, DS923+ should be better for that, mostly for large files and AMD processing of graphics isnt that bad. If you're only streaming plex, DS423+ probably best.launch

ARM processor and 2GB of ram. It's a potato, good enough as a backup for a real performing NASlaunch

@EgroegNosnhoj

At least it has an Intel CPU (I need transcoding), but not powerful enough to replace my DS916+ (now getting long in the tooth). Hopefully some of the Synology releases this year will include CPU with GPU capability - fingers crossed for a Plex- friendly DS924+ or DS1524 (unlikely though)! If not, then will be abandoning Synology Brand for NAS to replace/upgrade 916+ - have been following your uGreen videos with interest - lovely Plex-friendly hardware........ I will miss DSM 7.2 (which I love)! 😃launch

Buyers felt the diskless unit is overpriced for old hardware, citing $370-£500 base cost and over £1020 once drives are added.

@Cyberarmy-53

Thanks for the video. Yes the negative points you mentioned are true and Synology disappointed me a lot. They use old hardware for expensive money. Sorry I have already switched and am waiting for my new Nas which comes out in June. 👍launch

@davocc2405

Damn thing's £500 without drives. It's a plastic shell with a metal cover and an SBC - add a WD Red 8TB and this shoots up to over £1020.launch

$370 for a diskless NAS. Definitely outside my price range especially for an ARM, non-expandable system.launch

Some users experienced clunky performance, update loops, or freezing, and one called setup overwhelmingly complicated despite Synology's reputation for user-friendliness.

I unfortunately did not have much luck with synology , I had it for just under 2 years for basic home use , files/photos/plex , while the ability of being able get files of it via home network worked fine , I wanted Plex to work so bad and was a constant nightmare, the last straw was trying to get it to update and it sent me in this perpetual loop with this “offline” error , I built my own NAS with an old pc had lying around and used UNRAID , omg the difference in chalk and cheese. I just found synology most of the time just clunky and slow.launch

How responsive is this NAS? Did you experience any performance issues? I have a DS220j and it is so incredibly frustratingly slow with everything, it just freezes up for long periods sometimes :/launch

Certain hard drives (e.g. Seagate Exos) prevent sleep and create resonant noise, and the power connector is prone to slipping out during handling.

@mvp_kryptonite

When are Synology going to improve their power connector. Useless thing loves to slip out when I move the unit to cleanlaunch

@tonizombie

The only problem i have with mine is the noise from seagate exos drives, the system dosent let them sleep thus making noise every 5 seconds (I assume its the drive head moving) The drives also resonate very well with my desk making the noise even louderlaunch

Long-time users feel Synology increasingly restricts hardware compatibility similar to Apple, driving them to consider alternatives like UGreen.

@ZoneProduction448

I have a 918 & 412. Synology are getting more and more like apple, locking down on what hardware you can use. My next NAS upgrade will be an Ugreen if the software improves over the next few months.launch

At least one commenter criticized the unit's looks despite liking its specs for the price.

@strategystuff5080

its specs are good for its price, but man they made the exterior ugly as hell.launch
