> SATA SSD in 2011 was as fast as SATA SSD in 2018 That's a meaningless distinction, M.2 SSDs are incredibly popular and are nearly 10x faster than anything you could get in 2011 (for example, an OCZ Vertex 3 would max out at 550/500 MB/s sequential read/write speeds while a Samsung 960 EVO can do 3.2/1.8 GB/s).
