Stutter and disk usage [SOLVED]

Hello.

I've been trying to develop a mapping project which i have problems with.
When i run all layers at the same time it starts to stutter.
I checked on the resources dialog of my pc and noticed everytime stutter starts also the "Disk" is going from 30% average to 100%
Resolume seems to be using Disk at top so i dont know if its an issue related with my graphic card or my CPU. Wouldn't a saturation of processes affect CPU consumption rather than Disk?

Here is the specifications of the project im working out.

-Composition size set to 1280x720 and the mapping output set to 1366x760
-Every video clip is 360X480
-The composition has 8 active layers at all time.
-On the mapping output i have 14 active layers at all time
-I activated the option in advanced output to bring the signal directly from each layer to the mapping output, which means i have no effects working on the composition.

My laptop specs are
-Lenovo Ideapad 400y
-Windows 8.1
-Processor Intel Core i7-3630QM 2.40GHz
-Ram 6.00GB
-NVIDIA GeForce GT 750M 2gb

I checked the benchmark board Joris started 2 yrs ago and saw a slightly better computer than mine which had also similar limitations working around with up to 10 layers in 1280x720.
The point here is i dont know what is the problem: GPU, CPU, Disk (i dont know how that works, may i need a new one? too much processes?) or what.

Hope someone can help me with this.

Cheers !

do you play the content from an SSD?
is the content all DXV?

No, i run it from the internal HDD of the laptop.
And yes, all content is made on DXV3. I started rendering clips in 720 but i had to underscale them, always using DXV3

Edit:
I forgot to tell I also attached .wav sounds to 20 clips at least, which run at 3072kbps each.
The Disk still gets overworking even if no audio is used.

looks like you are reaching the read limits of the hdd.
reading 8 files simultaneously slows down read speeds a lot, because of the head seek times.

you'd need an SSD.

Really?

i have a SSD and never thought it would be a better option than my local hdd to run videos.
hope i can get it working all together.

Thank you very much.

Edit:
I tried the SSD and everything goes really smooth.
Thanks !
