The competitiveness decreases as the space needed increases. Let's say
you need 16TB of space. The following are the cheapest non-Seagate
drives, NVMe and 7200RPM.

$286.99 7200RPM 16TB:

$249.99 NVMe 4TB

So 16TB for spinning rust is $287, but the same 16TB in NVMe is $1000.

The other thing is that most motherboards I've seen can house a maximum
of 2 NVMes, and if you use both something or other gets degraded. So
16TB on one computer is very difficult.
