Samsung 970 Evo NVMe M.2 SSD 2TB Running Half Speed on T470 20HD r/w 1748/ 1685 MBps

Hello,

 

Samsung 970 is the best SSD in the market and it cost me 460 Euro to buy the Samsung 970 Evo NVMe M.2 SSD 2TB  in order to make my T470 20HD achive Read/Write 3.500 and 2.500 MBps. 

But this expensive SSD is running half of its speed on T470 20HD read and write 1748 and 1685 MBps. While most Laptops with Intel dual core ( https://www.userbenchmark.com/  )  with Samsung 970 Evo they got ( read and write speeds: 3.500 and 2.500 MBps respectively). 

 

 

T470 20HD read and write 1748 and 1685 MBps.

 From Lenovo website I bought this (Tray 1 for ThinkPad M.2 SSD drive Cost: Euro 30):

I am not fine with T470 20HD half speeds of read and write 1748 and 1685 MBps.

Looking forward to hearing from you
thank you in advanced.

The m.2 SSD in the T470, and its cousin the ThinkPad 25, is only supplied with 2 PCIe lanes.  Your measured speed is the best you're going to get.

Thank you I knew it. Anyway I send back the 970Evo 2TB. 

 

What Do you think for T470is it better to buy:

 

Crucial MX500 2TB with 560 MB/s Read, 510 MB/s Write

 

or I waite untill the release of Crucial P1 2TB with 2,000 MB/s Read 1,750 MB/s Read?

I would wait for the Crucial P1 2TB

 

is closer to the maximum bus speed of the T470 / T570

 

this would be a maximum theoretical speed

 

(Under normal circumstances, when Lenovo or Intel solve, I do not know what driver ....)

Regrettably ... I do not know what model can take advantage of speeds of

 

 3400 MB / s read

 2500 MB / s  writing

Check the particular model's PSREF page to determine the number of PCIe lanes provided to the m.2 slot.  It's good idea to check on the interwebs also - there have been occasional misprints.

 

The base spec link is sort of hidden at the bottom of each model's page.
