FreeCAD accesses external utilities (opencascade) to do the mathematical
calculations needed to specify a CAD design. If you change a parameter,
for example the diameter of a hole, FreeCAD recalculates the design and
checks that the hole does not extend outside of the design. Being able
to access opencascade at 7000Mbps vs an SATA3 drive at 6Mbps is
noticable.
I was able to install OpenBSD to the M2 nvme drive, the issue is my
BIOS, on a relatively new MoBO will not boot it. It's mainly a problem
with the MSI bios on a relatively new motherboard and that MSI supports
begs off by saying they only support Windows.
As a test, I installed Devuan to the M2 drive and the default GRUB menu
entry boots from the NVME drive.
I was trying to work around the unfriendly bios with a GRUB menuentry
that boots the M2 drive. I ran into the problem with accessing
/etc/random.seed on hd0a. I did try to dd if=/dev/random to
/etc/random.seed on the HD without success.
Thanks

On an MSI b840m-b board with a WD 7100 m2_2280 drive, OpenBSD installs
to the drive (sd0 option) without issue. On the other hand, MSI's bios
does not recognize the M2_1 drive as a boot option.
If the thing that is slow is writing the actual CAD files,
have /home (or /cad or wherever you do it) on the fast nvme,
having the system installed and booting from another disk
that your BIOS recognizes as bootable.
