JEYI PCIe 5.0 x4 NVMe Adapter Card 128Gbps

SKU CH-EEFB-XBP00

Adds a PCIe 5.0 x4 M.2 NVMe slot with 128 Gbps bandwidth, backwards compatible to PCIe 2.0, supporting 2230–22110 drives and including a 2U bracket

  • PCIe 5.0 x4 delivers up to 12,351 MB/s read and 10,119 MB/s write speeds
  • Works with PCIe 4.0, 3.0 and 2.0 slots for broad system compatibility
  • Supports M.2 NVMe lengths 22110, 2280, 2260, 2242 and 2230
  • 2R2 tantalum capacitors filter noise and prevent voltage spikes for stable power
  • 501 gold-plated connector pins resist corrosion and minimise signal loss

PCIe 5.0 x4 NVMe Adapter Card

This JEYI adapter adds a full-size M.2 NVMe slot through a PCIe 5.0 x4 connection. It targets builders who want to install a Gen5 SSD on a platform that already provides a native 5.0 link from CPU or chipset. The card accepts standard lengths from 2230 up to 22110 and works only with NVMe protocol drives.

Practical limits of PCIe 5.0 x4

Measured sequential throughput reaches 12,351 MB/s read and 10,119 MB/s write when the host delivers a full 5.0 x4 lane allocation. On 4.0, 3.0 or 2.0 links the card remains functional but bandwidth scales down to the host generation’s ceiling. Gold-plated 501-pin connectors and 2R2 tantalum capacitors protect signal integrity and power stability at speed.

Capacity and headroom

The slot accommodates any single M.2 NVMe module in 2230, 2242, 2260, 2280 or 22110 form factor. It cannot accept SATA or NGFF SATA M.2 drives. A system without native PCIe 5.0 lanes will not reach the advertised 128 Gbps ceiling, and the card provides only one M.2 position per bracket.

Highlights

  • PCIe 5.0 x4 delivers up to 12,351 MB/s read and 10,119 MB/s write speeds

Questions about this item

Which M.2 NVMe drive lengths does this adapter accept?

The card supports standard NVMe SSD lengths of 22110, 2280, 2260, 2242 and 2230. Note it is for NVMe protocol drives only and does not support SATA or NGFF M.2 drives.

What do the quoted 12,351 MB/s read and 10,119 MB/s write speeds require in my system?

Those figures need a full PCIe 5.0 x4 link from both the motherboard and CPU; on PCIe 4.0, 3.0 or 2.0 the adapter will run at the slower generation's bandwidth.

What bandwidth does the PCIe 5.0 x4 interface actually deliver?

The x4 slot provides 128 Gbps of raw bandwidth, which is the ceiling for any NVMe SSD installed in this adapter when the host system runs at PCIe 5.0.
