Absolutely correct.
If you have a motherboard that supports PCIe NVMe gen 3.0 x4 I would pick up a Samsung 960 evo or 970 evo 1tb drive. They are literally ATLEAST x4 faster than a M.2 Sata 3 drive or regular 2.5" SSD
Sata speed maxes out at 600/600 MB/s but typical speeds of 540/560 MB/s are seen with high end SSD drives. PCIE Gen 3 drive maxes out with 4,000 MB/s sequential read which is the current hardware limit until Gen 4 and Gen 5 come out and literally blow that speed out of the water with claims of being 6x faster than Gen 3.
This is a rock solid choice for a good drive. Price per performance? It's a No Brainer. Just do it.
