You can't upgrade firmware on OEM drives.

I just bought a desktop with the latest windows 10 and a AMD Ryzen 7 1700X on a
MSI X370 GAMING PRO CARBON AM4 AMD X370 SATA 6Gb/s HDMI ATX Motherboard. It had a 128GB Intel® SSD 600p Series PCIe NVMe M.2 SSD.

This drive was way too slow from what I expected.

I just bought a Samsung SM961 Polaris 128GB M.2-2280 PCI-e 3.0 x 4 NVMe Solid State Drive SSD-MZVPW128HEGM.

I used Samsung Data Migration to clone the Intel SSD to a Samsung 850 Pro and booted with that and took the Intel SSD off and put the SM961 on.

I booted the 850 Pro and was able to go to Windows disk management and formatted the SM961.

But after rebooting a couple of times the Windows file manager does not recognize the SM961.

Do you have any ideas to help me?

I have an I7-6700k with a Z170a MSI PC Mate MB and installed a Samsung 960 EVO M2 drive and it worked great.

Thanks,

Ken

I took the 960 EVO M2 from the I7-6700k and moved to the new AMD 1700x and used data migration to clone the 850 pro and was able to boot the new desktop with the 960 EVO M2.

I moved the SM961 to the I7-6700k and was not able to clone with Samsung data migration. I used Relect to clone it and it worked. Was able to clone new SM961 to a samsung 850 PRO with Samsung data migration for my backup.

New SM961 on I7-6700k is fast.

Use freeware Minitool partition wizard and use the menuoption Copy Disk wizard. Best software to control your harddisk.

* UPDATE 6/7/17 *

So I figured that I would post an update since it has been months since my last post regards to my experience with my Samsung SM961 1TB SSD.

What I have seem to have found is that the latest Samsung Pure NVMe drivers as of now (2.2.0.1703) appears to play much nicer with my SM961 SSD on Windows 8.1 Pro than with Windows 10 Pro when it comes to the Sequential reads on Crystal Disk Mark. So I do experience some issues with the Sequential reads when using 2.2.0.1703 drivers for Windows 10 Pro as others have mentioned (particularly lio256, post #356).

Is anyone using the newer 2.x drivers achieving +2600 MB/s Q1 SEQ read?
Why are the 2.x drivers being recommended over the 1.4.x driver for the SM961? The results below seem to indicate that you're better off with the older drivers.

New Samsung 2.1.0.1611


Old Samsung 1.4.7.6


What's more interesting is that on a clean Windows 10 install (Windows update never run) I get a different result from the new driver

New Samsung 2.1.0.1611 on fresh Windows 10 install


But no change using the old 1.4.7.6 driver



@Pano and I have been looking into these discrepancies, and trying to narrow them down. What I've noticed with the 1TB SM961 is that on the old driver you are getting much higher SEQ Read Q1 performance +600MB/s faster regardless of whether the Windows install is new or not.

We need more input from other members to see what exactly the differences are on the same hardware when running 1.4.x vs 2.x

I have attached a screenshot, detailing my current setup and software with the SM961.

Just received my first NVME. A 256GB SM961 purchased from Smithbuy. Firmware version CXZ7500Q with a production date of 03/2017. Will post results later. smile.gif

Are you sure of this? Is the reason commercial (no OEM firmware on Samsung website) or also technical (is there a lock on OEM drives?)

I am asking this, because the nvme command line utility on Linux have functionalities to download and activate firmwares on NVMe devices. It looks that the interface is standardised in NVMe drives. Any chance we could use them for updating OEM drives?
