Overview
The ASUS Hyper M.2 X16 Gen 4 Card is a PCIe 4.0 x16 expansion card that lets you install up to four M.2 NVMe SSDs in a single slot. It's an ideal solution for high-end PCs and workstations that need massive, fast storage. The card splits the PCIe 4.0 x16 bandwidth into four x4 lanes, giving each SSD full PCIe 4.0 speed.
Key Features
- Four M.2 NVMe SSD slots (M Key, supports up to 2280 length)
- PCIe 4.0 x16 interface (backward compatible with PCIe 5.0 slots)
- Supports RAID 0/1/5/10 (using motherboard RAID functionality)
- Includes both full-height and low-profile brackets
- Active cooling fan to keep SSDs within safe temperatures
Compatibility Guide
Your motherboard must support PCIe bifurcation (splitting the x16 slot into x4x4x4x4) to use all four SSDs. Compatible chipsets include Intel Z690/Z790/X299, AMD X570/B550/X670, and newer. Without bifurcation, the card may only detect one or two drives. It works in PCIe 5.0 slots but operates at PCIe 4.0 speeds.
Ideal Builds
- Content creators needing high-speed storage for video editing and 3D rendering
- Gamers who want multiple NVMe drives in RAID
- Workstation users expanding storage capacity
- Anyone whose motherboard lacks enough M.2 slots
Considerations
- Verify your motherboard's bifurcation support before purchase.
- The card occupies a PCIe x16 slot, so check clearance with your GPU.
- The active fan is quiet but not silent.
