Graviton 7HYY4 PCI-E 2*M.2 Boss Controller Adapter Card

SKU CH-YWMQ-7A0CX

PCI-E adapter card holds two M.2 drives and was pulled then tested in 2011

  • PCI-E interface enables fast M.2 storage expansion
  • Dual M.2 slots support two drives simultaneously
  • Boss controller manages RAID without extra hardware
  • New condition ensures reliable out-of-box operation
  • Supplier founded in 2011 with server-parts focus

PCI-E Adapter for Two M.2 Drives

This Graviton adapter card fits a standard PCI Express slot and provides two M.2 connectors for adding solid-state storage. It is aimed at system builders who want to expand internal capacity on a desktop or workstation board that lacks enough native M.2 sockets. The card uses a 7HYY4 controller to manage the attached drives.

Suited for Dual-Drive Expansion.

Builders who need two additional M.2 devices on a single expansion slot will find this card fits the requirement. It does not suit users who require hardware RAID across the two drives for a bootable array, nor those who need more than two M.2 positions from one card. The pulled-and-tested condition also means it is not a sealed retail unit.

7HYY4 Controller Drives Two M.2 Connectors

The onboard 7HYY4 controller is the component that enables both M.2 sockets to operate simultaneously from one PCI Express link. If the host platform cannot initialise this controller, neither drive will be detected. Verifying that the motherboard firmware supports the 7HYY4 is the single step that decides whether the card will work in a given system.

Questions about this item

How much power does the 7HYY4 card draw when it runs continuously?

The 7HYY4 is a passive PCI-E adapter with no active components, so its power draw is negligible during all-day operation.

What motherboard slot and M.2 drives must I already have to use the 7HYY4?

You need a free PCI-E slot and up to two M.2 drives that match the card's keying; the adapter itself requires no extra power cables.

Will the 7HYY4 work with older PCI-E 2.0 motherboards and legacy M.2 SSDs?

Yes, the 7HYY4 is backward compatible with earlier PCI-E generations and accepts M.2 drives of the supported physical size and key.
