Samsung Magician (the only Samsung software I know of) works 0 % with the SM961
Magician and SM961:
Magician and 850 EVO:
However, the Samsung software doesn't actually do anything useful except for updating the firmware. I used it to update my 850 EVOs firmware but obviously it cant do that with the SM961 since it doesn't even recognize it. However, Samsung pretty much never releases firmware updates for their drives like the XP941, SM951, and SM961 anyway.
