SSDs are still faster than hard disks even with sequential reads. 15,000 rpm enterprise spinning disks read at about 260 MB/s [1] while NVMe SSDs (like those in a 2015 MacBook Pro) reads at >1300 MB/s [2].

Was running some silly benchmarks that I ran before and clocked my disk throughput at about 100MB/s. On MBP got 800MB/s. I thought something broke (was hitting page cache or some trickery like that) or didn't compile things right. But no, tried other tools, looked online and it seemed correct. It really surprised me.
