Nowadays 2.5G device is more cheaper than 10G device.(Especially after April 2023,and furthur cheaper after June 2023)
(I means brand new device,not compare to second-hand 10G device)

Onedrive can hit max 200mbps speed but will drop to zero once every 10-20second and recover to max speed again. (With browser upload)
Dropbox,in my memory also fast,reasonable upload speed,accurate speed forgot already.

(IPv4)

I think it is still better than current D-Link crap...
Since it has a 2.5G Lan/Wan port for us who already have a 2.5G router to use.
And i think next year those newer mid grade router should come with at least 1x2.5G WAN and 1x2.5G LAN router.Just dont keep hope on 4x2.5G LAN router in current stage,it is still cost hundred on 2.5G switch chips.(which will cost up and only affordable on high end router)

Buy a 2.5G unmanaged switch now cost about
RM180(4/5 LAN Port + 2/1 SFP+) and RM240(8 LAN Port + 1SFP+)

U mean download with browser or google drive app?
Google drive file download with IDM or else apps should be able to hit max speed with multithread download.

you need to let the extension or software capture permission to capture the download link from browser and cookie in order to use download software to download.

Dont speedtest with that server,i had tried with multiple vpn to speedtest with it,all cant run more than 200mbps for download.
