disk tests on primary HDD about stressapptest HOT 1 CLOSED

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
