Hello fellow Lenovo lovers
I just got the brand new Lenovo ThinkPad T480 model
20L50000MD model with i5 and the 20L7001LMD with i7
Problem: I have the opportunity to upgrade them with the Samsung SSD 960 EVO m.2, but I can't find the speed on the SSD m.2 which comes with the laptops named: 512 GB SSD - (M.2) PCIe - TCG Opal Encryption 2, NVM Express (NVMe)
Even here in the datasheet I can't find a single clue on how fast the drive is or what brand it is. And when I tried to go to Lenovo's repair center to see what parts could be ordered to this laptop it just said that the laptop was not available for support or spare parts..
Can someone help me find the speed on these Lenovo SSD's ?

The T480 has its PCIe limited to 2 lanes, as such the read/write speeds are 1800/1500 MB/s. While the 960Evo is much faster than this, you will not be able to see the difference compared to the current 512GB drive.
Edit: You can find the model of your drive by going to Windows->Device Manager. I would bet this is a Samsung OEM drive that is similar to the 960Evo anyway.

Yes the m.2 connection is limited to 2 PCIe lanes (instead of 4). As such no matter how fast the drive is, the maximum you will see is 1800/1500 so save your money. The oem drive is as fast as it gets I guess, unless you upgrade to a 960Pro (not Evo) for the sustained sequential write (only for files larger than 13GB). Unless you write files larger than 13GB sequentially (4K video editing) then the drive you've got is the fastest you need. (If this is a Samsung drive, it chances are it is, it should be the 981 drive, that is the newer version of the 960Evo, so don't bother).

I checked mine awhile back for my T480 in the System information & Device mgr as you suggested above.
Mine is: System Model 20L5S01J00
w/ a PM961 SSD, MZVLW256HEHP-000L7 by Samsung
Interface PCI Express Gen3 x4
I am totally happy w/ the speed, size, weight, just about everything.
I did upgrade the W10 Home to Pro for the added features.
