10GB > 25GB network worth it?

[Mattcee2]

I've been running my office network at 10GB speed but am finding pulling some large video files from the NAS into my video editing program (Davinci Resolve) takes up to 20-30 seconds sometimes.
I don't know that much about networking but my NAS is purely used for mass storage and working from those videos with x2 different PC's.

Here is what I have now:

x2 PC's which have 10GB ethernet built in to my Asus motherboards.
Synology 1821+ NAS with x2 SSD's for caching + 10GB network card
RAID 10 with x8 16tb drives
QNAP 10GB switch
Cat 7 cables.

I've been looking into M.2 NAS systems but for now, they don't offer enough storage or work out too expensive but the M.2 speed would be nice.
Copying the video files to my local M.2 drives is to much hassle as I use many per day.

So... I've seen some info about 25GB speed ethernet and has got me wondering, would this make things much faster than my current 10GB set up?
I know I'll need a new 25Gb switch, NAS 25Gb network card and x2 PC network cards but I don't mind paying for that if I get a notable transfer increase.

Has anyone gone down this route or knows if its worthwhile me doing this?
For reference, copying a near 9GB file now from my NAS to desktop takes about 18 seconds at 490MB/s.

10GB > 25GB network worth it?​

Short answer NO

490 * 8 = 3.9.gbs

Your problem is not the network capacity but the speed at which your NAS or PC is transferring data
Confirm that your network between the NAS and PC can utilise 10gbps - use iperf or something to verify that it can transfer more than 3.9gbps then work out where your bottleneck is. Personally I think it's the NAS and not enough SSD caching

Thanks. I am very tempted to get the QNAP TBS-h574TX NAS which has a x5 bay for SSD only but most importantly, has x2 Thunderbolt 4 connections that could feed into each PC (or Mac If go down that route again).
That should be really fast but limits me to just 16TB really and isn't particularly cheap.
