About the Product
For maximum speed in a small package, look no further than the Samsung XP941 M.2 PCIe SSD. The 256GB model provides up to 1080MB/s read and 800MB/s write sequential data transfer rates, far exceeding the performance bottleneck of SATA-based SSDs.
The SM951 boasts outstanding performance, supporting both PCIe 3.0 and PCIe 2.0 interfaces. Samsung's SM951 comes in the M.2 form factor. The drive's compactness is well suited for most notebook PC designs, freeing up space for other components including the battery.
