Thanks so much - that's very useful information and a very detailed screenshot.

I see the tray for m.2 SSD can be ordered from Amazon (I searched with the part number).

Do you know if the screws (to fasten the tray) are included?

The are shown in some of the illustrations but not all.

I just now finished installing the second m.2 NVMe SSD using this tray [smile]
The screw for the tray actually comes with the P50 ("preinstalled"). The screw for attaching the m.2 SSD to the tray is included.
The storage kit is not here yet. It seems to be quite a PITA to get one of those apparently, my assistant managed to get one through the only shop that had them on stock and could ship immediately, I do not know how she did that. Today I tried ordering another one for a costumer and I did not find a single shop that had it on stock...
BTW: Amazing machine, with three addidtional cheap Kingston DDR4 RAM (no ECC) modules  that also arrived a few hours ago I now have 64GB of RAM and currently run 6 VMs very smoothly. I am in awe of this machine [love]

Here's my first benchmark of the Samsung 950 Pro NVMe vs. the non-NVMe Samsung SSD that came preinstalled with the P50, it's a MZNLN512HMJP or so:

FWIW

1) There is an overpriced kit from Lenovo that includes a 2.5" cradle and the proprietary cable.  Ordered it on 5 May and it's supposed to appear today.  I hope it does because there's a Samsung 2TB Pro SSD waiting for it.
2) Mister B, I'm hoping to see an SSD benchmark next to your nvme and your non-NVME (which I think is properly called "m.2 SATA").  Thanks for the post!
3) Does anyone have an ideas about what should go where?  I'll have the 2TB 2.5" SATA SSD and probably a terabyte of m.2 Nvme.  So...
- where should the OS go?
-I want my VMs to run super-quick, so I want to put them there also?

This thing is truly awesome and I can't recommend it highly enough to anyone who'd like a data center that they can stuff in their laptop bag.  I'm just going to have to get a whole heck of a lot smarter about Hyper-V to get the most out of it.

The storage-kit arrived today, so here it is:

re 2.) the 2.5'' SATA is pretty close to the m.2 SATA ("non-NVMe") SSD, that was quite what I expected.

re 3.) I can't wait to hear what more experienced guys than me think about where to put the OS. I can't decide if I'll go for HYPER-V or VMware workstation although the latter seems to be a dead end in the long run. But at the moment VMware WS seems to offer much more convenience.

The storage kit is quite interesting.

If you take the big panel off the back, it looks like you've got a standard-sized bay for a 2.5" drive, and to the left there are two smaller bays for the m.2 drives.  Then there's a square hole at the far end of the 2.5" bay.  So I'm saying, "how the heck do I get a cable in THERE?"

But then my whole brain kicked in and realized that

1) There aren't really two m.2 bays... it's really just ANOTHER 2.5" bay with a low line of foam rubber to delineate two m.2 bays.  Nothing stops you from skipping the m.2 drives and just installing two regular 2.5" drives (if you had them already).
2) You get two SATA cables, but odd-looking ones.  On the "motherboard side," there is a small -- quite small -- snap-on surface connector.  Closer inspection reveals the mating ends for the two SATA cables right on the motherboard.

So right now I've got the 2.5, the m.2 SATA and the m.2 nvme.  Neat!

I would strongly suggest, BTW, going to Hyper-V.  I've loved VMWare Workstation for years but the Hyper-V that comes with Windows 10 answers many of my objections about the old H-V and adds some features that VMWare never had.  (As well as PowerShell support.)

And a disk benchmark screen shot, two m.2 NVMe versus a regular old 2.5" SATA 3 SSD.  

disks.png 


C: and D: are both Samsung 950 Pro 1/2 Terabyte NVMe PCIE m.2 drives
E: is the Samsung 2 TB SATA 3 Pro SSD.

I EXPECTED the m.2s to really kick the SSD's butt, but note how the factor changes.  The first read is 5x difference, the writes are much closer.  Don't know enough yet about NVMe to understand it, but eventually I hope to.

Are the NVM PCIe drives creating much heat - from what you guys can see?

That is supposed to be the downside:

(And some other sources - various demonstrations on YouTube with some software that measures heat level)

Good question, David... I will try to find out.

Meanwhile... there's a 1TB m.2 NVMe stick. [smile]
