NAS Download vs Online Download: Why are external servers faster?

At home I have a QNAP with you.a. Pictures and videos. If I want to watch them on my mobile phone in the same Wi-Fi network, it takes a long time to show them. In addition, it takes Google images, YouTube and Netflix not even seconds to load the content.

Why are external servers so much faster than my home server?

How can I speed up the speed?

Because you load the external images with a browser and do a prefetch, so download the images in the background before you pounce on them

Time 2 things in advance:

Consider your NAS has probably installed HDDs which work at best with 100MB, probably more towards 50MB.

Then your data is probably uncompressed on the NAS.

…

On the Internet, the data for the Internet are optimized, which also means that the files are smaller. Etc.

Because the data is compressed from the internet…

So you do not get to see the full quality… Unless you download them…

I have full gigabit speed on my nos by Thecus… But I also looked at gigabit enabled hardware…

Can you specify the gigabit hardware?

How accurate is the download speed? Measure how long it takes to copy a large file from the NAS to your hard drive. And compare that to downloading from a webpage. I suspect that the NAS is much faster.

If you get only 100 MBit / s in the NAS, then you should try to upgrade to 1000 MBit / s. For this we would have to know which router and which QNAP model you have.

Basically, only the router and the NAS gigabit need to be capable of doing this. And the LAN cables should be at least CAT 5e type. With WLAN it is however already more difficult to reach the full 1000 MBit / s. Since you have to have a good wireless adapter in the PC and a router that supports the speed synonymous.

I only have small business switches from Cisco and Kat 7 wiring in house…

Fritz! Box 7390 and QNAP TS 451+.

The QNAP is connected by cable to the router and the 1 Gigabit in FritzOS enabled "Power Mode".

My hard drive is the Seagate IronWolf 3TB with RAID 6 with 4 hard drives.

QNAP after I have 2x Gigabit Ethernet Port (RJ45). I can imagine that the slow connection comes through the network cable. I use the enclosed cable from QNAP.

I do not think QNAP would fix a bad LAN cable there. Is your PC connected via LAN cable? On the cables is usually on it which type it is.

And how fast is the transfer of files? At 1GBit / s you should ideally achieve almost 125 MB per second.
