before i start opening my case i want to know if i can swap one samsung for another? both are ms=25

not sure how that works... im guessing if you had the FW keys for both you could... thats an assumption though

I agree. There was however a thread someone created on how to swap to a different brand drive. Maybe that will shed some light if you can find it(Search around).

it worked i just had to flash the xtreme 3.0 from my old drive.
