G752VS - Issue Detecting Second SSD to Create RAID 0

[DragosBT]

Hello,

Few months ago I have bought a Notebook ROG G752VS-BA178T and I decided to give a try to create a SSD RAID 0.
The problem is I cannot see the second SSD to allow me to create the RAID 0.

The SSD that was shipped with the laptop is TOSHIBA 256GB XG3 M.2 PCIe 2280 THNSN5256GPU7.
Notebook BIOS version is the latest G752VSAS306.

I bought another similar SSD, and it seems to be detected fine and works perfect in AHCI mode:


In RAID mode, as you can see in the attached picture, I can see only the original one, but not the new one.


I tried to update the SSD firmware for the new one, but Toshiba SSD Utility says it is up to date.

I see the firmware ID differ between the two:

The original SSD:
Serial Number: 66KS10AZT7BV
Firmware Rev: 57XA4104

The new SSD:
Serial Number: 177S10BNTUFV
Firmware Rev: 57GA4103

Is the Notebook BIOS the problem? Is the SSD firmware?

Any suggestion is appreciated.

What happens if you were to shut it down, pull the original then go into bios and look?

I removed the original SSD and the situation is the same. The new one is not detected in RAID mode.

The new one is a different revision, even if they looks the same and they are the same model.
Hmm.. looks like a BIOS detecting issue. Is there any chance ASUS to include soon new revisions? :cool:

I wanted to share this information, maybe it is useful for the people who wants a RAID 0.

It seems the second TOSHIBA 256GB XG3 M.2 PCIe 2280 THNSN5256GPU7 was incompatible and I had to return it.

In the meantime I found something else:

SSD ADATA SX8000 256GB PCI Express 3.0 x4 M.2 2280
Drive Model: ADATA SX8000NP
Drive Firmware Revision: C2.2.1
NVMe Version Supported: v1.2

It is not as fast as TOSHIBA, but it works perfect even in RAID 0
Now I have a RAID0 with TOSHIBA and ADATA.
