How to fix studdering on pcsx2?

[jDSX]

I got into PS2 emulation and was wondering during my games, I noticed that get studders randomly when playing pcsx2 with suikoden V and SMT nocturne, I do not know if it's because my games are playing off of my external hdd which uses a 3.0 usb connector and the port is only 2.0 usb port or if I cannot emulate using my GPU in hardware mode also my temps are in the 50-65c so I know it's not throttling .

my pc specs are core i5 3330@ 3.2ghz 16gb ram strix gtx 960 2gb 120gb ssd 2tb hdd

It's easy to test if the USB HDD is the bottleneck. Just copy a stuttering game onto your SSD and try it from there.

The ps2 is supposed to read of a DVD drive.. Unless he has his disc fragmented as hell this shouldn't be a factor...
However, @jDSX try to copy the iso into your SSD and check if same thing happens

I got around this by turning off VSync , also are you emulating in software mode or hardware mode?

Hardware mode I am pretty sure
