Slow NAS with Ubuntu and mapping a sabma share to fix it

Installed TerraMaster F4-210 with Refurb Hitachi 7k4000 drives in Raid 0, so it should have been pretty fast.
When connecting to the drive and moving files, I was sitting at about 50MB/sec, a few spikes to 60, and some drops to 40. While disappointed, I saw people getting more like 30MB/sec, so I figured that's all I'd get.
Moving on, I knew that I needed to have the NAS mount on boot for my Plex server, so I looked into that. I used a Samba share, using this website's directions:
https://www.ghacks.net/2009/04/19/auto-mounting-a-samba-share-in-linux/
sudo mkdir /[name]
 

My fstab entry:

(remember, sudo gedit to get to the graphical text editor to edit this file)
//[SAMBA IP/FOLDER] /{DIRECTORY] cifs credentials=/[PATH TO CREDENTIAL FILE],uid=1000,gid=1000 0

for the credential file, create a doc with:
username=[USERNAME]
password=[PASSWORD]

Note:
Install cifs with sudo apt install cifs-utils

Cool, this works.

BUT...

When I went to transfer files to my NAS, I jumped to 75MB/sec steady. Some spikes to 88MB/sec as well.
