Running steam games from an external hard drive

Hey guys , recently my steam library has been coming up to 400GB+ and i simply have no space left on my internal drive

My solution was to move everything to my 500gb 5400rpm external hard drive.

I know this is possible and the games will run , but will i suffer any preformance related issues with the drive not being fast ?

I run all of my steam games from my external 1tb drive, runs perfectly fine, loads the same speed as if they were on my main drive.

loading from an external will be slower.

youll be fine running off an external unless you have a super fast internal HD there wont be that big of a difference.
