Question The best actual driver for Samsung 960 Pro 1 TB NVMe

Jul 12, 2019
Hi Everyone.

I´m new to the forum and looking for some help with the Samsung 960.

I have a Lenovo Yoga 900-13ISK2 80UE about a year ago I swapped the original PM951 512 GB SSD (NVMe) to a the Samsung 960 Pro 1 TB (also NVMe) successfully. Everything seems to be working fine, as both SSDs the old one and the new one are NVMe apparently the same driver was good for it to booth and work. Using the Microsoft NVMe driver.

The speed is nice and seems same as to the original SSD but I keep having the feeling that it may not be using its full speed as there is no specific Samsung driver I could install to maximize its operation. I have the same problem with the Magician software about getting the message that the drive is not supported.

I keep getting a message from Intel drive update to updated it to their RST driver latest version but I´m afraid to run into problems as to stop being the drive recognized or other problems.

Can anyone give me some recommendation?

Thanks, Roger

Numbers will tell the tale, rather than feelings.

Run CrystalDiskMark, and see what it says.

I this info of any help or please I appreciate if you advise what to look for.


use hwinfo to find out more about your motherboard

open it, and click on Motherboard on the left, and in the right pane, you will see PCIe version. tell us what that it please.

mine at work it pathetic, it's PCIe Express v2.0, ugh. I need a new box, it was suggested above yours might only be PCIe 2.0, if so, that explains your numbers.

Samsung does have it's own NVME driver in the downloads section.

From what I read on Lenovo's forum, the M2 port appears to be wired with only 2 PCIE lanes so you will get half speed but there are so many sub-models of this that you cant be sure and I couldn't find any benchmarks.
