Why does only ArmA 3 stutter because it is installed on a HDD?

[Maq___]

Hi to all!

My laptop has an SSD and an 1 TB 5400'' Toshiba HDD.

I have installed GTA V with a tons of mods,and NBA 2K18 on the HDD and they work perfectly!

Only ArmA 3 gives me stuttering and huge FPS drops when installed on the HDD.
I installed it on the SSD and the stuttering and the FPS drops had gone.

But,I would like to keep it installed on the HDD,so I would please you to tell how do I keep ArmA 3 on the HDD but fix the stuttering issues and FPS drops?

Please tell me.
Thanks to all in advance.

You cant.

The HDD cant operate at the speed your SSD does, that's why you are getting the stuttering on when the game is on the HDD.

There is no getting around it sorry, other than replacing the HDD for another SSD.

You've already proved to yourself what's causing the stuttering -- the necessary fix should therefore be obvious.
