My understanding is that both the T460p and T470p support PCIe 3.0 x2 via their SATAe SSD connector. The T470p has an adapter on which an M2 2280 PCIe NVMe drive can be connected and get speeds higher than SATA.
The T460p on the other hand only has this one Toshiba SATAe drive to improve on SATA speeds, and that is limited to 256GB, it is rare and cancels the WAN port for further storage.
So, can the adapter from the T470p be used in the T460p? This would solve all problems for the T460p, higher speed and good capacity.

It is not eSATA I am talking about but SATAe, SATA Express. SATA Express uses the SATA interface + the bridge in between the two connectors (mechanically identical to the U2 connector) for the additional PCIe Lane.
My understanding is that the SATAe connector can use up to 2 PCIe 3.0 Lanes. When a SATA drive is connected only one lane is used and the other one is left for the WAN m.2 slot. When a SATAe drive (the infamous Toshiba) is connected, because it uses both PCI lanes, there are none left for the WAN m.2 slot and as such a SATA m.2 drive cannot/will not work. There is evidence for that on that guy's Youtube video, who tried the M.2 WAN slot with and without the Toshiba SATAe drive and only worked when the SATAe drive was not connected.
So comming back, does the adapter connect to the the T470p mainboard with anything else apart from the SATAe connector? Do we have close up pictures of this adapter?
Thank you for your time.

I have now checked pictures of the adapter from this thread and indeed the connector looks exactly like SATA Express. It can, however, be a U.2.
Has anyone tried this on a t460p
There is an adapter on sale to connecte 2 M.2. SATA drives on a single SATA Express connector. With this adapter you can have two M.2. drives (SATA) working independently, as one is using the one PCIe lane and the other the other PCIe lane of the SATAe bus. They work both at full speed at the same time (it is not a SATA multiplier). Again with this adapter you cannot use the WANN, however you can use long 2280 M.2 SATA drives (not PCIe), two of them, if you need more space in more than one drive, as the M.2 SATA 2248 drives are up to 512GB only.

it appears that the T470p adapter is an M.2 to U.2 adapter. While the U2 connector is mechanically the same as the SATAe connector on the T460p they are not the same.
As such I think I will leave it at that. That the T470p has a U.2 connector for the 2.5 drive and the T460p has a SATAe (SATA Express) connector for the 2.5 slot.
As such the T460p cannot use the adapter from the T470p.
At least this is my understanding.

I have a ThinkPad T460p and am considering to do an upgrade from the preinstalled 500 GB Sata SSD to M2 or NVME SSD?
1. Is it worth it - in temrs of performance and price?
2. If so, which type of SSD do I need to buy M2/NVME and which caddy to convert T460p to accept this new SSD?

Is it worth it?
We'll on paper the NVMe gives you 3x performance. 1700mb/s read and 1500mb/s write (pcie is limited to 2x). So benchmarks will reflect that.
Unless your work demands sequential reads and writes (video rendering etc) you will not be able to tell the difference in performance in real life.
However, given that NVMe drive prices are much lower than they used to be, the upgrade from SATA is not that expensive. The price difference is still 2x compared to SATA but it's bearable. So it's up to you.
What you need?
An m.2 pcie NVMe drive. The Samsung's are great but don't pay for the pro version of the 970 series as even the evo is going to saturate the (limited 2x) bus. Look for drives with speeds close to the limits of the bus stated above, 1700/1500.
You will also need the cardy from the t470p (not the t470 that has a separate cable). Look further up on this thread for the FRU (part number). They're about $40 new but availability and time to deliver might be another issue. There won't be easy to find outside lenovos network.
