I have tested PrimoCache for 30 days. And now, the trial period is over.
I did not see a great speed improvement. But this is not the most important thing for me. If someone could ensure me that this software makes HDD / SSD life longer... I will buy it.

Since some info and stuff is taken from the RAM memory, my guess is that HDD and SSD should be less stressed.
So?! Should I buy PrimoCache?
