Plotting how many plots with my system

CPU: AMD 5950X
Mainboard: Gigabyte Aorus B550
RAM: 128GB
SSD: 2x Intel 2TB U.2 SSD
2x Seagate M.2 SSD
HDD: 1x Seagate 12 TB

How many plots can i do at once and how would you guys do it? Interval of 15 Minutes wich SSD to wich?

Where is the bottleneck atm?

Can you send me a plotting strategy you would use?
