I am trying to put together a file server and trying to get as many
SATA ports as I can. I found a motherboard I like but it only has 6
SATA ports. It also has PCI-Ex8 and PCI-Ex16 slots. I want to add a
SATA card. Supermicro makes an 8 port SATA card that is PCI-Ex4.
Can I use a PCI-Ex4 cards in a PCI-Ex8 or PCI-Ex16 slot? If so then I
can have 22 SATA drives in this box.
Yes, you can use a card that uses a smaller number of PCIe channels in a
larger slot - the reverse is not true of course. The card won't be any
faster than if it were plugged into its native slot but it works correctly.
This means you can use a x1 card in a x1, x4, x8 or x16 slot, a x4 card
in a x4, x8, or x16 slot and so forth.
