Samsung XP941 512GB M.2 PCIe SSD Review

Desktop Test System

Today, we're using our custom ASUS test system with the Bplus adapter for this review. In a few days, we'll test the drive in the new ASRock Extreme6 motherboard with a native Ultra M.2 connector.

ATTO - Baseline Performance

Version and / or Patch Used: 2.34

PCIe can be tricky. Today, we're using Intel's Z87 chipset, but you'll get better performance from Intel's high-end platform, which uses the X79 chipset or the upcoming X99 chipset. We've found a lot of performance variation between Z87 motherboards and even among the PCIe slots on the same motherboard.

We bring this up mainly because of the ATTO results below. In our Z87 test system, the read performance dropped off in the middle transfer sizes, but this didn't happen on our X79 system. We still managed to achieve 1069 MB/s sequential read and 1027 MB/s sequential write speeds.
