This clearly shows how much faster an SSD is than a rotating HDD. In fact the SSD on this ma-
chine is limited by the SATA II interface which only supports up to 300MBps. That SanDisk
should be capable of about 550MBps on a SATA III interface. NVMe disks on a PCIe interface
are even faster, the 1TB NVMe SSD on my new machine has benchmarked in excess of
1500MBps.
