The SM951 boasts outstanding performance, supporting both PCIe 3.0 and PCIe 2.0 interfaces. For use in the latest ultra-slim notebooks, it can read and write sequentially at 1,600MB/s (megabytes per second) and 1,350MB/s respectively based on PCIe 2.0. This performance level is approximately three times faster than that of the latest SSD with a SATA interface and about 30 percent faster than that of the Samsung XP941, its predecessor.
