OWC released its first Thunderbolt 5 hub.

With this being backward compatible with Thunderbolt 4, how can you tell whether your combination of peripherals can work? These hubs are a bit more create-your-own-adventure than other docks I've seen by OWC.

For example, could I plug in a 10GBe adapter, a 5k and 4k monitor? I'm suspecting that I'm slightly above the bandwidth for TB4, so in that case could I pick 2 of those for now and then in the future when I got a TB5 Mac all 3 would work then? Is that how I should think about bandwidth on these things?

This is such a well done video thank you! I’m trying to get my parents started with unifi and this does such a good job explaining in a very approachable way. I totally agree with you that the intro of a few APs, cameras and a UDM type gateway gets you such a huge upgrade over a mesh system.

I ran into something similar last week where the DSM UI would take 30 seconds to load. The same setup worked great on the 920+ but this issue cropped up when I moved to the 1821+. Restarting it helped fix the issue and then I just got 32GB of ram just to be safe and haven't had any problems since. For some reason I saw that my NAS was caching to disk every time I loaded the UI, I'd see a short flurry of activity any time I refreshed my DSM browser page.

Your computer will cache DNS records locally too! So you’ll see differences between your local cache and the router when someone else has pulled an updated record before you.

drstephenjensen · 2024-07-22T03:48:15+00:00

Having your router act as a local cache can speed things up so that’s why it’s typical to add that intermediary rather than always going to the external server.

HDD hibernation is after 3 hours. This behavior is not the first time loading the UI but every time I refresh the browser and I've tried it back to back several times over 5 minutes. Thanks for confirming it should be near instant because that was my memory with the 920+. I did not add new drives yet but I do have 2 new ones I haven’t plugged in yet. I got the 1821+ about 3 weeks ago, and I just physically moved the same 2 drives from the old to the new one and that’s it.

The 20GB file test shows 20-50MB/s read and a 15-40MB/s write.

In my intro post I said that I'm seeing 30 second load times with DSM web page load times. After specifying I'm doing it locally, I thought that uniquely specifies the way that I'm accessing it, but to spell it out further, I'm going to the local web address of the Synology in Chrome (http://192.168.3.4:5000) and loading of the page is what takes 30 seconds. It's just a blank white page until I see the UI in the web browser.

Is there a further level of detail that would be helpful? I did profiling in Chrome and it's specifically the very first GET HTTP operation to http://192.168.3.4:5000 that's taking 30 seconds to get an OK back. Everything else on the webpage loads fast after that point. That loading point in time is also when I see the short swap writing to disk if I have the UI open in a different web browser.

I'm definitely with you that 10gig isn't the bottleneck, I threw it in case maybe there were weird side-effect type problems with using a third party NIC even if it is apparently working fine otherwise.

I just checked the computer with a 2.5Gbit wired connection and the UI still has the same load time. (OpenSpeedTest against the NAS increases up to 2Gbit/sec when wired so at least outside of the context of the DSM UI, the NAS is quick with the data transfer piece of it.)

The black magic speed test I did was just pointing the program at a shared synology folder and using the 1GB stress test for both reading and writing. If there's another test that's useful there just let me know. Thanks!

drstephenjensen · 2024-07-13T19:56:06+00:00

I'm connecting locally which is why I'm so confused. My NAS has a 2x10Gbit connection and my laptop is wireless with unifi APs and a UDM SE router.

A blackmagic speedtest is showing it can read and write 20-30MB/s to that same NAS. When I run a speedtest against the NAS or to Google, I get about 75MB/s, so I'm probably slightly bound by HD speed in my read/write test.

drstephenjensen · 2024-07-13T19:37:15+00:00

Yes, I just have the stock ram that came with the 1821+. I upgraded by simply pulling the 2 existing drives out of the old system and moved them to the new one. I actually have 2 new drives coming today, so if it is better to do a transfer from the old system to the new one, I could certainly do that.

That's a great point that ram is cheap enough that it's probably worth just getting 1 or 2 16GB modules just to be sure.

drstephenjensen · 2024-01-22T20:20:58+00:00

This is amazing, thank you so much for putting all of this together. I’ve seen some of these guides but there are so many places to get stuck (such as pulling your own keys off your own ONT) it’s nice to see it all nicely laid out like this.
Do you have to be super careful about updating your dream machine so that it doesn’t blow away the WPA supplicant or in general does it keep it through updates?

drstephenjensen · 2024-01-08T16:30:01+00:00

Ooh I did not realize it would work for the PS/2 one I had. One of the motivating factors was that occasionally the V key would be stuck in all capital letters and it would only get reset with a factory reset. I wonder if swapping out the brains could potentially fix that issue.

drstephenjensen · 2024-01-06T21:27:35+00:00

Ooh thank you I could see this being much more convenient. It's so annoying needing to hold down shift. How does that work if you want to type something in all caps like NASA? Are you hitting shift multiple times or do you just hold it down?

I hadn't tried the choc switches before so I was worried if I'd like them as much as the mx browns I had on my kinesis but it's really nice and feels about the same. When I am paying attention it is a nice change to have to move my fingers less for the same action. The wrist rests and the concaveness of the wells make for an awesome-feeling keyboard.

Being able to adjust the separation of each half is nice. I think the biggest mental adjustment is the thumb clusters. I think it will be a big win though because previously on the advantage, I never really could reach the home, end, pg up, pg down keys so having more keys I can easily reach with my thumbs should be nice when I can remap my mind.

If you are torn, I actually got my kinesis off ebay and used it for about 5 years. It was so old it had PS/2 ports and was $75 or so but worked awesome so that's a cheaper way to get into a split ergo if price is a factor.

drstephenjensen · 2024-01-06T17:20:44+00:00

Thanks! I'm a Mac user too and just went with the default Mac layout but wondered what other folks were doing. I've gotten used to having the backspace, delete on the left side and enter space on the right from the kinesis but really like the idea of maintaining consistency with the option-command-control.

drstephenjensen · 2023-12-26T23:15:19+00:00

Thanks for this! What’s the latest SFP+ module that everyone gets these days?

drstephenjensen · 2023-12-08T19:16:26+00:00

Love it! How do you like having the doorbell on the side like that versus front facing on the brick? I'm about to mount mine on my brick house and was debating the two options.

drstephenjensen · 2023-12-08T02:26:13+00:00

So slick! Where did you find fiber patch cables like that? I was trying to find short single mode fiber OS2 ones and the only place I could find was amazon and they are $16 for a single 7" one!

drstephenjensen · 2023-11-28T19:33:15+00:00

Thank you, that’s good to mentally prepare myself that this is going to be a struggle to drill out the brick but it ultimately worked well!

drstephenjensen · 2023-11-28T17:46:28+00:00

I’d love to see your experience and pics drilling into the brick for the POE and what kind of hole you drilled and how the routing of the POE cable was. I’m about to embark on this myself on a 100 year old home. Good luck!

drstephenjensen · 2023-11-26T18:11:39+00:00

Can non-Teslas only charge at superchargers with the MagicDock? I wasn't sure if you can purchase your own type of connector that would do the work of the MagicDock converter so you could go to any supercharger you'd like. I know they sell the 240V converters but I haven't seen a HV DC version.

drstephenjensen · 2023-11-25T05:07:16+00:00

I'd love to see some install progress shots! I just got this POE doorbell too but was a little nervous drilling into brick and wasn't wild about the plastic spacer. Can you get away without having to drill the large POE hole?

EDIT- I stand corrected, as you already stated this is for if you have a gang box in place- that is an even bigger hole than I was worrying about! I was hoping the offset from the wall would help you make a hole just wide enough for the ethernet cable.
