I should have mentioned that the 960 EVO is now identified correctly by Samsung Magician. It is no longer a jumbled up mess of characters. This got fixed when I changed the SATA mode in the BIOS from RAID to AHCI.

Yes buddy I know its the same thing for me, there is an alternative to magician to get data about the SSD it is called : Crystal Disk Info. With that you get the number of working hours, ssd health, temperature, total reading/writing etc...

Im in the same boat as you I have a 950 256GB PCIe ! But still the SSD is running strong and fast as it is.

Because our windows has been installed with the RAID configuration, I read it has to be in AHCI mode but well I can live with that, supplier is wrong with his answer, our laptop are fine lol.

If it really bugs you out try this : www.tenforums.com/.../45011-samsung-950-pro-nvm-express-driver.html

Dave - it's worse than I thought. It looks like it doesn't support trim, which is bad. Using Macrium Reflect to back up and restore partitions, a write is preceded by a trim command. This usually reports success, but the 960 reports nothing.

This is in a recovery environment - nothing to do with windows. However, the environment includes all necessary drivers, so it could I suppose be a driver issue (there is no Samsung NVME driver in my system).


Crystal Disk Info reports poor quality data, and also confirms no trim support.

this is terrible news. I have 17 R3 and was going to throw away the PM951 256gb for Evo 960 1tb.

Crystal Disk Info reports poor quality data, 

Can you support that statement in any meaningful way?

TIA

By poor quality, I mean only raw values (not Current /Worst/Threshold), and parameter IDs that are significantly different from those of an 850 EVO (for example no Error Counts, Reallocated Sector Count, Wear Leveling Count, etc, etc).

I am coming to the conclusion that the 960 series is so new that current software tools cannot cope with it - not even Samsung Magician. The pdf guide for the latest Samsung Magician 4.9 states that this version now supports the 950 PRO M.2!

I have no idea what function the Samsung NVME driver v2 performs. It doesn't seem to have any effect. It shows up in device manager as a storage controller, but the drive itself is using Microsoft drivers.

OK - I think I was correct in my assumption that current software tools are not working well with the 960 series.  Samsung have just updated Magician to version 5, and it is clearly a major update. It has a revamped UI and now works well with my 960 EVO.

Version 4.9 with SATA mode in the BIOS set to RAID:

Version 5 with SATA mode in the BIOS set to AHCI and Samsung NVME driver v2 installed :

I am guessing that the Samsung NVME driver is required to enable TRIM? It is perhaps best at this stage to be suspicious of drive information provided by other software tools.

I also have 2015 R2. I have Samsung 850 EVO 1 TB on Sata Port, Samsung 951 256 GB on PCIE x2 link  and Samsung 960 EVO 1TB on PCIE x4 link. Of course I am countinuing with Intel RAID (which has AHCI/NVME drivers built in). So only Samsung 850 EVO is shown in Samsung Magician with remaining 2 NVME disks as unknown device. Samsung needs to improve magician. I am not worried about Trim since trim is inbuilt from Windows 8.1. I have other notebooks where I am using built in trim (120 TBW so far on two different 850 EVO SSDs). Only problem is though I am getting 3200 MB read and 2000 MB sequencial writes, IOPS are only 120,000 and 110,000 respectively. What IOPS you are seeing in samsung magician after switching to AHCI.

Trim is built in Windows 8.1 onwards. Samsung magician recommends to use built in trim support on my other machine for 850 EVO.
