Running games

First time user here of HDD so i have a question. While playing a games,i experience big frame drops and lags during the gameplay,is this caused somehow by the HDD or there is some other problem ?
I’m using WD Passport device

Same story bro.

HDD cannot be the only problem, everything depends on what you do on your PC and how strong is it. If the problem is with HDD that the best way and the easiest in my opinion is to replace it with a good SSD, the most of cases are solved like this. Otherwise, there are external boosters, but they costs a little bit more. I am using one of those because we are playing on different accounts from the same computer, so it needs a lot of power.
