Four M.2 slots for NVMe expansion

The Vszerda SI-PEX40162 adds four M.2 M-key sockets to a desktop, server or workstation through a single PCIe 4.0 x16 connection. It is built for users who need to run multiple high-performance NVMe drives simultaneously. The card targets enthusiasts and professionals building storage arrays or adding capacity to platforms that lack enough native M.2 slots.

PCIe 4.0 x16 host link and bifurcation requirement

The card connects via a PCIe 4.0 x16 interface and divides those sixteen lanes into four x4 links, delivering up to 256Gbps of aggregate bandwidth across the four slots. A motherboard and BIOS that support PCIe bifurcation are required to recognise all four drives; without bifurcation only one module will be detected.

Fits x16 slot and accepts common M.2 lengths

The board measures 9.5 in by 5.0 in by 0.75 in and occupies one full-size x16 expansion slot. It accepts 2230, 2242, 2260 and 2280 form-factor drives and includes a large heatsink with an active fan plus a two-phase power design rated for 19.8W per drive to maintain unthrottled speeds. Compatible with AMD Ryzen Threadripper sTRX40 and Intel VROC RAID configurations.

Questions about this item

What does the 256Gbps figure mean for real-world drive speeds?

The card delivers up to 256Gbps aggregate bandwidth across four PCIe 4.0 x4 M.2 slots, so each NVMe drive can run at its full rated speed simultaneously.

How does the PCIe 4.0 x16 interface limit performance if my motherboard lacks bifurcation?

Without CPU or chipset bifurcation support, the x16 link presents only a single x4 lane group, so the board will detect just one M.2 drive instead of four.

Will the 9.5 in by 5.0 in card with its heatsink fit in a standard full-height PCIe slot?

Yes, the 9.5 in length matches a full-size expansion bracket, the 5.0 in height clears typical motherboard spacing, and the .75 in thickness fits a single-slot opening.
