Seagate recently announced the 14TB Mach.2 hard disk drive, with a maximum sustained transfer speed of 524 MB/s. This would put its throughput in line with many conventional SATA SSDs and several times faster than other commercial HDDs.

Good, now can we abolish SATA QLC SSD's?

Wow, what a stupid way to cut their own sales outlook.
These are obviously targeting servers. Using SATA is what would ruin their sales figures.

What makes you say that? It's an enterprise drive and SAS is common there. That's where the money is. The enterprise sector has growth potential. Which certainly can't be said for HDDs in general. Consumer demand for them is dying. These drives were created for the likes of Google or Facebook. How many consumer devices ship with 3.5" HDDs these days? And how many contain enterprise-grade drives?
Exos line has SATA drives in it as well as SAS drives. So, it is possible that they will release a SATA version in due time. A possible complication is that they present the drive as two independent units. SATA allows port multiplication. But it's more finicky than the exclusively enterprise SAS which has greater capabilities. Controllers aimed at consumer applications don't always play nice since consumers don't use this much at all. Technically, it's doable. Whether the market is there, is another question. Also, it seems like they expect to exceed throughput of SATA III, perhaps in second generation. And so they believe SAS is a better bet.
As I wrote, in the enterprise world, it doesn't matter that much. You can get SAS directly on motherboards without AOC, even for workstations and not just servers. And it's not like you pay substantial premium for SAS drives over SATA (from the top of my head, I can't recall any premium at all). Interface is not what makes a drive expensive.
