Vszerda

Vszerda Dual M.2 NVMe PCIe 3.1 Adapter Gen3 X8 X16 Low-Profile Bracket

SKU CH-CDCH-ZT0MR

Adds two M-key NVMe SSDs in 2230, 2242, 2260, 2280 or 22110 sizes to a PCIe 3.1 x8 or x16 slot using an ASM2812 chipset that avoids bifurcation

  • Add two NVMe drives without motherboard bifurcation using ASM2812 chipset
  • Supports M.2 2230, 2242, 2260, 2280 and 22110 lengths
  • Single-drive read up to 3.5 GB/s and write up to 3.2 GB/s
  • Includes low-profile bracket for small-form-factor systems
  • Enables software RAID 0, 1 and JBOD via OS or third-party tools

Dual M.2 NVMe PCIe 3.1 Adapter

This adapter installs two M.2 NVMe SSDs into a single PCIe 3.1 x8 or x16 slot on a desktop workstation or server. It uses the ASMedia ASM2812 chipset so each drive operates on its own x4 lane without requiring motherboard bifurcation support. Builders adding fast storage to a system with a free full-size slot can use this card.

Practical limits of the PCIe 3.1 x8 interface

The card fits PCIe 3.1 x8 and x16 slots and is backward compatible with 3.0, 2.0 and 1.0 standards. Each SSD receives a dedicated x4 link, so total throughput is capped by the slot generation and the drives themselves. Single-drive speeds up to 3.5 GB/s read and 3.2 GB/s write are possible, but actual performance depends on the specific SSD and the host platform's PCIe bandwidth.

Check your motherboard and drives before ordering

Verify the board has an available PCIe x8 or x16 slot and that its firmware can boot from NVMe if you plan to use a drive as the OS volume. The adapter only accepts M-key NVMe SSDs in 2230, 2242, 2260, 2280 and 22110 form factors; it does not support SATA-based B+M or B-key drives or PCIe AHCI SSDs. A low-profile bracket is included for small-form-factor cases.

Questions about this item

Should I pick the 22110 or 2280 slot for my drive?

The board has two M-key sockets with adjustable standoffs; both accept 22110, 2280, 2260, 2242 and 2230 lengths so you can fit any supported NVMe SSD in either slot.

What do the 3.5 GB/s and 3.2 GB/s figures mean once the card is installed?

Those are the quoted single-drive sequential read and write ceilings over a PCIe 3.1 x4 link; actual throughput depends on the specific SSD and the motherboard's available PCIe bandwidth.

Does the x8 edge connector cap each SSD to x2 lanes?

No — the ASM2812 chipset gives each NVMe SSD its own PCIe 3.1 x4 path without requiring motherboard bifurcation, so neither drive is limited to x2.
