Re: NVME Drive for X260

Well, just to verify that the SSD was indeed not a dud, I tested it in my desktop which has two NVMe slots. It was detected right away, so I figured I'd run a quick benchmark.

 

For an x2 drive it performs quite well. I would really like it to work in the x260, it's rougly 3x as fast as the SATA SSD in read, and 2x write. I really hope this isn't the case of Lenovo "white list" problem of only allowing its own certified devices in the WWAN slot.

 

If so, not a huge loss, I can use this SSD in my PC.

Re: NVME Drive for X260

Hmmmm... I noticed something... When I was taking out the Lexar SSD from my Asus Desktop motherboard, I noticed a different notch in the slot. The Asus Desktop board has an M-Key, while the X260 has a B-Key slot. The Lexar SSD has notches to fit both types of slots, so I don't know now, but perhaps this slot will never work for a NVMe SSD, since all the M.2 NVMe drives I've seen pictures of, including my own Samsung 970 Pro in the primary NVMe slot on my desktop motherboard, have only M-Key slot, and SATA M.2 SSD's have B-Key.

 

I might just be confusing my brain here, so what do you guys think? Here's a pic of the difference.

Re: NVME Drive for X260

The primary differences between b and m keying in relation to NVMe SSDs is that b keyed connections only provide 2 PCIe Lanes, vs m key provides 4 lanes. That is only an issue if the PCIe device is keyed for one or the other. This drive is keyed for both, so that isn't an issue.

Re: NVME Drive for X260

Oh, good to know. To be honest I don't remember reading much about the M.2 keys recently, only after NVMe drives starting becoming popular a few years ago, and the M.2 slot also being capable of SATA SSD's, and those being B-Key.

 

Thanks for the explanation.

Re: NVME Drive for X260

It looks like both can handle SATA (if the motherboard has that built-in), but I assume most mSATA SSDs are b-keyed because they can't use the extra bandwidth provided by the extra 2 PCIe lanes.

Re: NVME Drive for X260

Just curious what your bios revision is. I hadn't touched mine in a while, but just recently ran the Lenovo Vantage app and updated all the drivers and also BIOS.

 

Mine is 1.43.

Re: NVME Drive for X260

I'm also running version 1.43.

 

Unfortunately after lots of playing around with BIOS settings and lots of research, I'm unable to get the drive to be recognized. I read that some NVMe drives aren't immediately discovered by even BIOS until you disable Secure Boot and run a Windows 10 install. Somehow the Windows Install prepares the NVMe drive.

 

I find it very odd that there is an entry in the Boot Order in the BIOS for "NVMe0", so it seems that it should be supported in some way or another.

 

My suspicion is that it might be a whitelist issue as I've read that there is a whitelist of supported WWAN cards which would also not allow any other card to work in that slot.

Re: NVME Drive for X260

Yeah, looks like we might be out of luck. I guess thats what we get for being guinea pigs, hehe.. As for the NVMe0 in bios, thats probably for the 2.5" NVMe drive.

 

Nevertheless, I'll pull my SATA SSD out, and see what happens with a freshly created Win10 1903 usb installer. To see if it sees anything at all.

Re: NVME Drive for X260

Nope, didn't work. Disabled secure boot, Win10 setup started, cannot find a drive.

It's just not visible to the OS or the BIOS.

Now if we only knew how to hack the BIOS and remove the whitelist... I was lucky enough to download a modified BIOS for my x220 that removed the WLAN restriction, and upgraded that to an Intel 7260 AC card.

But at least in the X220, the WWAN slot was not restricted from using MSATA in it.
