Does the number of PCI-E lanes affect the number of hard drives I can connect?

Question

Hard disks

I was recently asked this question, and I realized that I have a serious gap in this knowledge.
Is there a limit on the number of SATA devices that I can connect to one pci-e line?

Answer 1

Limited by common sense and the lack of controllers for more than 5 devices per line (more precisely 4, I have somewhere with 1 eSATA outside and 4 sata inside, it remains to be seen if this external one is rummaging around with one of the internal ones).
Common sense should say that the speed of one pci-e channel may not be enough for more, although it should work according to the mind.
ps usb devices in a computer can be cram hundreds (127 per controller, usually 2-3 on the motherboard, or even in each port), i.e. a bunch of hubs, a bunch of usb-sata controllers and a bunch of smut, because all this will slow down

Answer 2

It doesn’t matter, taking into account mining, there is almost no load on disks, but if plotting, then yes, it is important for a large number of disks
