What should i do??
 

I need to decide what storage i will use for my laptop but i am not completle sure.

1.Option:
2x 7200rpm 750GB HDD in Raid 0

2.Option:
750GB 7200rpm hdd and one 128GB SSd.


So what you think what is better for an gaming laptop?

Second choice with games of said choice on SSD.

^^ditto.
The ssd will provide a very noticeably boost in system responsiveness, and game load times. 2 x 2.5'' raid hdd's will run hot in a laptop.

Ok and do you know where i can find out what ssd is in the MSI GT780DXH i712912BLW7H?(I had no luck whit that)

Because i don't want that it will be an slow ssd whit no Trim support.

Apparently it's an Intel. No sweat.

MSI Global - Computer, Laptop, Notebook, Desktop, Mainboard, Graphics and more

If that was mine I'd pull the HDD and add another matching SSD in RAID-0.

Nice book by the way. When I saw the first few websites that listed it as 11.6" I was jealous until I realized it was 17" like any other dual-2.5" SATA laptop.

I'm waiting for multi-mSATA books. :)

Single SSD will be faster than two mechanical drives in RAID 0

Yep, and 2 SSDs in RAID-0 will be even faster.
