A modern SSD will give you a speed boost for drive read/writes. If you look at your performance manager, you can see of that is your bottleneck.
The problem with current drives is that they are TLC/QLC based, so the long term data reliability is sketchy at best and as you read/write cycle it or fill it beyond about 50% the speeds will drop off dramatically and it will end up slower than a decent spinning plate drive.
If you can find an old SLC drive, those are great.
Hit me up on email or pm if you want to discuss in more detail.
