Yeah, I noticed that too.

Hi Crimson,

I removed the SSD's and reseated them and also I had one copper and one plastic heat shield swapped around and seems all good now. The copper shield was on the C drive, seems to have done the trick.

As for Transfer Mode, it came upon one of the drives but then disappeared again.

Anyhow, I have restarted the laptop a few times, and it all good for now.

Mine also disappearing like before when I had an outdated bios, now I have the latest bios and its still disappearing. An Alienware 17 R4 here. 

@Gelbuilding I am running a clean install Windows 10 like I always do and the bios is upto date. And it works fine on AHCI, also It uses pciex4 lanes on AHCI. Been using like that for years.. and you can do raid windows install as well. And do please tell you technicians to post.  

Hi Fahim,

I read somewhere about disabling raid and Convert from RAID Bios Setting to AHCI Bios because the driver is in Sata and not using the PCIe x4 lanes, that's why it's not showing up on Crystaldiskinfo.

I hope I'm making sense, lol.

I won't dare touch the BIOS I will end up screwing up my OS.

I'm waiting for my technician to come over and get him to fix it.

I`ll get him to post on this thread so he can explain it better.

@Gelbuilding Bro it uses standard NVME controller. It never was on SATA. Unless its a SATA port, not pcie x4 port. Its usually ssd bios update problem. 

Definitely using Sata the NVMe`s read-write values are too low.

When I installed my two NVMe SSD's I remember seeing SSd1 Is PCIe and the second one PCIe/SATA.

Like you mention it's all to do with the BIOS.

Check out this post below I found, this guy didn't even get one reply!
