Why did the USB guy fail the multiple choice test?
Answer at the bottom of the blog
PCIExpress is Everywhere!
I asked Richard Solomon, our USB Technical Marketing Manager, “Why is PCIExpress everywhere?”:
“Everywhere there’s not a cable perhaps – USB to connect things across cables, PCIe for everything else.
It IS kinda amazing that we’ve got small M.2 form-factors for PCIe/NVMe SSDs, tons of WiFi chips with PCIe, so lots of random gear with WiFi has PCIe in it. Likewise the SSD connections – they’re great for industrial stuff so Internet Of Things tend to have a lot of small PCIe connections in them for “stuff”.
Not too many OCuLink cabled external disks, Blu-Ray drives, etc though.
Don’t forget automotive – your little “lane assistant” is pretty much a 1980s supercomputer and it’s using PCIe to connect processor cores.”
