Please provide any additional information below.
I am trying to get the speed of the primary hard drive, in other words the 
speed of the drive the os is running on. I do not care if this is by using -d 
or by using -f but I would prefer to use stressapptest as I am already using it 
for some other tests. I am able to get -f info for USB drives I have in the 
system, but not the primary SSD drive. Attached you will find the output of the 
terminal window where I have attempted to get the SSD information.

You are trying to write to /file.1, but you probably don't have permission to 
write to that directory. "-f ~/file.1" should fix this. Two file threads will 
put more load on your ssd so that may be preferable. Storage benchmarking can 
be somewhat complex so the number you get from stressapptest will not give you 
a complete picture. 

I would suggest: 
stressapptest -s 20 --stop_on_errors -W -M 4096 -f ~/file.1 -f ~/file.2
