Hi everyone!

First post here. I have one main question about setting up the RAID 1 array on my G751JT and another question about the laptop.

1. Does the controller support RAID 1 array?
Like after you have installed intel Rapid Storage, change sata settings to RAID, do you have an option to create a raid 1 array, or just raid 0?
If my laptop already has windows 10 installed, would setting up a RAID 1 array srew up my data?

2. How can I tell the specific model of my JT, such as the letters and numbers behind JT...

Many thanks!!!

hi obi123,
RAID on G751 serie isn't something ordinary - so there isn't much info out there on the web about RAID + G751 serie.
What mater for RAID isn't your sepcific JT-xxxx model, but your major model type ( JT ) and the current EFI ROM module within the BIOS ( I.E your BIOS version installed )
let me explain it:
The G751 serie features the Intel® HM87 Express Chipset, which suppors AHCI and RAID from a chip made by Intel - this chip is the same in all the JT's submodel,AFAIK.
According to Intel official HM87 Spec (http://www.intel.com/content/dam/www/public/us/en/documents/product-briefs/mobile-chipset-hm87-brief.pdf), this chipset supports RAID 0,1,5,10.
So in HW terms, the laptop supports RAID - again, AFAIK, cuz Asus didn't really publish something about RAID, not even in the Manual. (http://dlcdnet.asus.com/pub/ASUS/nb/G751JY/0409_E9959_A.pdf)

NOW....
which IRSTe ( = Intel RSTe = Intel's drivers & software for RAID maintenance, the "e" in the end says it is version above 11.5+) is better ?
After running BIOS 211 in UBU tool (http://www.win-raid.com/t154f16-Tool-Guide-News-quot-UEFI-BIOS-Updater-quot-UBU.html), you can see that the internal EFI ROM Module ( a package, part of the UEFI BIOS ) for RAID is at version 14.6.0.2285 -> thus, as Win-RAID forum suggest (http://www.win-raid.com/t2f23-Intel-RST-RSTe-Drivers-newest-v-WHQL-v-WHQL.html)(just beneath "Additional informations regarding the newest Intel RST/RST(e) "), you should install same main version IRSTe that matches you EFI ROM.
I.E for EFI ROM v14.6.0.2285 you should install any IRSTe version starting with v14.6.x.xxxx
This should give you best performance & STABILITY.

How to know for sure if the JT supports RAID1 ?
A. Please note that if your current SATA configuration is AHCI... then you need to change it to RAID, reboot then enter again to the BIOS to get the IRST menu.
B. see that GUIDE (http://rog.asus.com/447422015/labels/guides/guide-install-m-2-pcie-ssds-in-raid-0-for-speed/) - follow only what's there under "Now head to the Advanced page and look for the IRST (Intel Rapid Storage Technology) option"... and continue till you get see the popup-menu of "RAID Level"
If you decide to go for RAID - make sure you CSM is DISABLED... ( as you really want to use UEFI... .and CSM disabled = UEFI enabled )


Hope that info helps.
Please share with us your findings... it's interesting...

Last but not least - using the same UBU tool (http://www.win-raid.com/t154f16-Tool-Guide-News-quot-UEFI-BIOS-Updater-quot-UBU.html) - you can update ( MOD ) the BIOS to support RAID EFI ROM v14.8.0.2377.
Note that this Might only effect RAID working mode BUT IT DOES NOT EFFECT AHCI AT ALL !
Also, I do not know to say if will help or worsen the RAID stablity and performance - so trial & err is the right "weapon" here....
Once again, Please share with us your findings, if you could. Thanks and good luck :-)
