Aside from them, discrete graphics cards are history, just as disk controllers were a few decades earlier. DIMM slots are going too. The primary storage will be built in. (The industry missed a great deal there.)

Discrete disk controllers are still around.

My last deskop had a PCI SATA card that I added after I exhausted all of the on-motherboard SATA slots.

My current one has a JBOD USB Mass Storage enclosure.
