I just upgraded my G71GX with a new order of my G750JX, which should be here early next week (and I'm quite excited). The machine looks like a beast, but I have a few questions I'd love answered to prepare for when it gets here.
I have a 42mm m.2 NGFF SSD, which I was told was compatible with the G750JX (also shown from here -- http://www.mydigitaldiscount.com/m.2-ngff-ssd-compatibility-list.html -- ). Is there some motherboard slot I can stick this into, or should I start trying to put it to other use? If there is, where can I find it (and would it void warranty getting to it)?
Secondly, in the G750 version with "256GB SSD RAID0", is that in the 2.5" drive bay?
Lastly, could someone tell me which motherboard the G750JX uses?
As far as I'm aware the G750JX doesn't come with mSata, it comes with a 2.5mm solid state drive and a 1TB Mechanical drive, sometimes even without the SSD. The one you linked seems to only have the mechanical drive.
If you want to use your mSata, you may need to grab a daughterboard or which ever they're called and plug it into the drive bay, not sure if you need a caddy for it or something.
The 256GB SSD RAID 0 is rubbish I believe, it's actually a normal sized 256 SSD partitioned into two 128 gigabyte drives. (At least mine was) It's not RAID 1. So your mSata chip might be useless. There's no slot on the motherboard dedicated for inserting the single chip as far as I'm aware.
