75,000 MB/s corresponds to 75 GB/s. No hard disk in the world can do that. You always have to distinguish between internal and external transfer rates. The external one is limiting here: 6 Gb/s (SATA III), which corresponds to 0.75 GB/s. This is the absolute maximum you can expect from the hard disk. From experience I can tell you that with a 'normal mix' of files over 10 min you will reach a maximum of about 23 GB/min. However, I am very satisfied with the hard drives in my NAS. However, they are not intended for a workstation or a gaming computer. There are other, more suitable products, mostly in 2.5" format or - better - SSD (NVMe).
