ASUS Hyper M.2 X16 PCIe 3.0 X4 Expansion Card V2
Brand: ASUS. This expansion card supports four NVMe M.2 drives with Intel VROC and NVMe RAID on AMD Ryzen Threadripper. It features a two-phase power design delivering up to 14W output and supports transfer speeds up to 128 Gbps when used with VROC. Suitable for enthusiasts building high-capacity, fast-storage RAID arrays, particularly on Intel and AMD platforms that support NVMe RAID configurations.
ASUS Hyper M.2 x16 Gen5 Card (PCIe 5.0/4.0)
Brand: ASUS. This PCIe 5.0/4.0 card supports four NVMe M.2 drives with bandwidth up to 512 Gbps. It includes a 6-pin PCIe power connector and a two-phase power solution delivering up to 14W. A large heatsink, thermal pads, and an active cooling fan help maintain performance, while an extra fan cable allows control from the motherboard chassis header. Ideal for systems pursuing max throughput and modern NVMe support.
GLOTRENDS PA54 Quad M.2 NVMe to PCIe 5.0 X16 Adapter
Brand: GLOTRENDS. This four-slot M.2 NVMe to PCIe 5.0 X16 adapter supports up to 512 Gbps bandwidth and works with 2230/2280 form factors. It enables software RAID configurations across Windows/Linux/macOS and requires a PCIe bifurcation-capable motherboard. It accommodates X4X4X4X4 or Hyper M.2 X16 modes, with caveats for certain configurations and licensing for VROC in enterprise setups.
GLOTRENDS PA41 Quad M.2 NVMe to PCIe 4.0 X16 Adapter
Brand: GLOTRENDS. This four-slot M.2 NVMe to PCIe 4.0 X16 adapter supports up to 4 NVMe drives and software RAID configurations. It requires a PCIe bifurcation-capable motherboard and is suitable for multi-drive RAID setups on older or budget-friendly systems upgrading to M.2 NVMe storage with RAID capabilities. Note licensing considerations for VROC may apply on some platforms.
10Gtek Dual M.2 NVMe SSD Adapter Card
Brand: 10Gtek. This dual M.2 NVMe adapter uses a PCIe 3.0 x8 slot and requires BIOS bifurcation support to recognize both drives. It expands storage bandwidth by enabling two M.2 NVMe SSDs to be accessed concurrently, making it a practical upgrade path for desktops seeking additional NVMe lanes without a full multi-slot card. Supports 2230/2242/2260/2280 form factors.
GLOTRENDS PA52L Dual M.2 NVMe to PCIe 5.0 X8 Adapter
Brand: GLOTRENDS. This two-slot M.2 NVMe to PCIe 5.0 X8 adapter delivers up to 256 Gbps bandwidth, supports 2230/2280, and offers software RAID configuration. It requires PCIe bifurcation on the motherboard, and is suitable for users who want RAID capabilities on a budget-friendly 5.0×8 lane setup. Licensing considerations for VROC apply similarly to other enterprise-grade configurations.
ASUS Hyper M.2 x16 Gen 4 Card
Brand: ASUS. This Gen 4/Gen 3 capable card supports up to four M.2 NVMe drives and offers a two-phase power solution with up to 14 watts output. Its heatsink and active fan cooling help maintain performance under sustained transfers, making it a solid choice for AMD TRX40/X570 or Intel platforms seeking reliable four-drive NVMe RAID with high bandwidth (up to 256 Gbps).
Buying Guide
- Drive count and bandwidth: Choose a card that matches your RAID goals—four slots provide large arrays, while PCIe 5.0 cards maximize available bandwidth.
- Motherboard support: Verify PCIe bifurcation support in BIOS. Some motherboards require enabling bifurcation to recognize multiple NVMe drives.
- Power delivery and cooling: Look for two-phase power, a robust heatsink, and optional fans to prevent throttling on sustained workloads.
- RAID method: Decide between hardware RAID (supported by some cards with VROC licensing) and software RAID (via OS). Hardware RAID can offer CPU offloading but may require licenses.
- Form factor and compatibility: Ensure drive form factors (2230, 2242, 2260, 2280, 22110) are supported and that the card fits your case and motherboard layout.
- Software and OS compatibility: Most solutions support Windows, Linux, and macOS via software RAID. Check driver availability and ease of setup for your environment.
- Noise and cooling considerations: Active cooling and large heatsinks help maintain performance during long RAID transfers, especially with Gen4/Gen5 cards.
