Finally got my SM961 in. Here are some comparisons to the 950 Pro in the same PC.
Looks pretty good.
Is that 5% CPU usage spike just a random blip or is it consistent?
The 5% is a spike. It is generally between 1% and 2%, which is slightly higher than the 950 Pro.
The reason for this may be because the SM961 uses the standard Windows 10 NVMe driver while the 950 Pro uses the optimized Samsung NVMe driver.
RamCity Youtube channel says it can use the same driver.
