Buying expansion & controller cards at HodlChip

An expansion card adds the connections your motherboard lacks. Choose by what you need:

  • M.2 adapters: fit an NVMe SSD in a PCIe x4 or x16 slot, many with a heatsink or a small fan. Some also hold an M.2 SATA drive, which connects through a separate SATA cable.
  • SATA and RAID controllers: add two to six SATA ports for extra hard drives and SSDs, or connect SAS and SATA drives through a RAID controller and breakout cables.
  • USB cards: USB 3.2 Gen 2 and 20 Gbit/s Gen 2x2 ports at the rear, or internal headers for front-panel ports. Some need a SATA power connection.
  • Serial and parallel ports: for industrial, lab and older devices that still use them.

Before ordering, check three things: a free slot that is long enough, the PCIe generation and lane count (a PCIe 3.0 x4 card runs one NVMe SSD at up to about 3.5 GB/s), and the bracket height, as many cards include a low-profile bracket for slim cases. Find drives in NVMe SSDs, and bay adapters and more M.2 cards in drive mounts & accessories.

Questions about expansion & controller cards

Will a PCIe x4 card work in an x16 slot?
Yes. PCIe cards work in any slot that is physically at least as long, and they run at the lower of the card's and the slot's lane count and generation. Check your motherboard manual, as some x16-length slots are wired for fewer lanes or share them with M.2 slots.
Can I boot from an NVMe SSD on an adapter card?
On current UEFI motherboards, yes: they can boot from NVMe drives in PCIe slots. Very old boards without NVMe support in the BIOS may only use the drive for data.
Can one card hold two NVMe SSDs?
Cards with their own switch chip can. Simpler dual cards split the slot's lanes and need a motherboard that supports PCIe bifurcation on that slot, for example x4/x4 or x8/x8, so check the board manual before buying.
