NVMe in Predator G9-793-78RV + RAID/AHCI

Hey all.

 

Hope you are well? I recently purchased a G9-793-78RV Acer Predator after being out of PC gaming since the early 2000s. Much has changed and I am trying to get my head around it all. I upgraded the stock 5400rpm Toshiba HDD with the Samsung 850 EVO 500GB 2.5 with no problems. Working great.

 

However I know the spare M.2 slot is free and was looking to install a PCIe M.2 drive.

 

I have a few questions. Do both of these slots support x4 PCIe or only one slot? I heard one was 2 channels and the other 4? If so can I get a NVMe and install it in the top free slot and it will work to its full potential? I also need to purchase the steal bracket to secure it. Mind you have been quoted $50 Australian for the bracket with shipping which seems expensive for a little bit of steel, yet that is another issue.

 

Secondly if I can put an NVMe drive into my Predator my current drive controller is configured as RAID in the BIOS. Samsung Magician states I should change it to AHCI for my SATA SSD yet there is no where in the BIOS I can see to change that? I believe NVMe is seperate from IDE, RAID and AHCI? Am I correct? Sorry I am confused a little. So do I need to change it from RAID (if possible and how?) for my installed SATA SSD and if I can install a NVMe drive in the second slot?

 

Again I am confused and sorry if this post is all over the shop. lol. In the end do I need a NVMe drive for gaming? Will I notice it over the standard SATA M.2 Drives?

 

Thanks for reading and your replies.

    You won't even notice the difference between a hard drive and ssd when it comes to gaming, except more loading times but otherwise the fps is the same on both drives.

    Acer have set the the HDD and the SSD in RAID in order to enhance the speed of the HDD and sacrificing some storage and SSD speed.

    I think to change from RAID you need to go in BIOS and see if there is such an option.
    Always post the following characterisitcs of the device:
    -Model number
    -Part number(not required, but helpful)
    -CPU
    -GPU
    -Operating system

    Helios 300 and Nitro 5 users DO NOT update the BIOS to version 1.22 if you don't want the keyboard's backlight to turn off after 30 seconds even when the device is plugged in.

    Thanks for the reply ven98. I found the 5400rpm was causing a bit of stutter and texture pop in comapred to the SSD.

     

    Appreciate the information. However the BIOS has no option to change from RAID.

    not 100% true, slow HDD can create micro stuttering or short freeze on heavy games, since it tooks more time to load files (expecially textures), so having an HDD+SSD RAID is not totally good.

     

    your model is lacking any AHCI options, so you need to use RAID; nvme will use it's own driver and you can use the samsung nvme if you bought a samsung nvme SSD.

     

    by the way, you can destroy the actual array using a proper tool from Acer:

     

    Symptoms
    User can't delete RAID array, RAID option greyed on BIOS.
     
    Diagnosis
    User can create the RAID array via "Intel Rapid Storage Technology UI" (iRST) on Windows but can't delete RAID by "iRST" and RAID is the only option on BIOS (AHCI option is missing).
     
    Before deleting the RAID array
    Always remember to do the windows recovery media before running the RAID tool to delete the array.
    With the help of the Acer Care Center (pre-installed on your system), you can create the windows recovery media on an USB stick, so you can reinstall it later.
    In the AcerCare Center, click Recovery Management -> Getting Started, and then follow the instructions.

    You can also perform a backup of your actual windows installation, so using the windows recovery media, you can reload your OS at the time of the backup.
    Press Windows logo key and type "backup"
    click on "Backup and restore" and then follow on screen instructions.

    Solution
    First of all, check the Volume name of your array on "iRST".
    Press windows logo key and type "intel"
    click on "Intel Rapid Storage Technology"
    click on "Yes" if prompted
    check on the right side, under "Storage System View", that "Volume_0000" or "OEMRAID0" is the name of the array.
     
    if Type description is:
    RAID 1 or Recovery - no data will be lost
    RAID 0  - all your data will be lost - you will need to re-install Windows
     
    Download the RAID tool
    ftp://ftp.acer-euro.com/Notebook/Predator/G9-793/RAID_Tool.zip
     
    Right click the downloaded RAID_Tool.zip file  
    click on "Extract all"
    Click on "Browse..." 
    Click on "Computer"
    Click on "C:" (normally it's labeled "Acer (C: )
    Click on "Ok"
    Click on "Extract"
     
    Now click on the Windows logo at the bottom left of your screen
    Click on the Power icon
    Press Shift key and click on "Restart"
    On the next screen click on "Troubleshooting"
    On the next screen click on "Advanced settings"
    On the next screen click on "Command Prompt"
    Select your account and type your password (if any)
     
    At Command prompt 
    type C:
    type CD Raid_tool
    type delete
     
    Once successfully deleted, press Enter and then reboot your PC.
    The RAID array will be deleted.
