Mallow Carrier Board: Request for Currently Available Industrial NVMe SSDs (M.2 Key-B)

Technical Support
,
1

Hi,
We are currently working with the Verdin iMX8M Plus module along with the Mallow carrier board and are looking to integrate an industrial-grade M.2 NVMe SSD.
While going through the community threads, we found that the following SSDs were previously tested and confirmed to be working:

  • Western Digital CL SN520 NVMe SSD

  • Toshiba Memory Corporation BG3 NVMe (KBG30ZMV128G)

References:

However, both of these SSDs seem to be discontinued or not readily available in the market anymore.

Could you please suggest:

  • Any currently available industrial NVMe SSDs compatible with the Mallow board (M.2 Key-B, PCIe)?

  • Whether there are any validated adapter solutions (Key-M to Key-B) that work reliably with modern NVMe SSDs?

We are specifically looking for a solution suitable for long-term availability in an industrial/embedded setup.

Any guidance or recommendations would be very helpful.

Thanks in advance!

Mallow Carrier Board M.2 NVMe Configuration

Based on the Mallow Carrier Board V1.1 datasheet, the board provides M.2 Key B connectivity for NVMe SSDs through the PCIe interface (1). The M.2 connector (X17) includes:

  • PCI Express 1 lane (1)
  • USB 2.0/3.0 (1)
  • SIM card for cellular applications (UIM signals, Card Detect) (1)

M.2 Key B Pinout Details

The M.2 connector provides the following PCIe signals (1):

  • PCIE_1_LO_RX_N (Pin 41, SODIMM 232) - Negative differential PCIe receive signal (1)
  • PCIE_1_LO_RX_P (Pin 43, SODIMM 234) - Positive differential PCIe receive signal (1)
  • PCIE_1_LO_TX_N (Pin 47, SODIMM 238) - Negative differential PCIe transmit signal (1)
  • PCIE_1_LO_TX_P (Pin 49, SODIMM 240) - Positive differential PCIe transmit signal (1)
  • PCIE_1_CLK_N (Pin 53, SODIMM 226) - Negative differential PCIe reference clock signal (1)
  • PCIE_1_CLK_P (Pin 55, SODIMM 228) - Positive differential PCIe reference clock signal (1)

NVMe Wiring Considerations

From the community discussion, for NVMe drives, the I2C connection (MFG_CLOCK, MFG_DATA) is generally not required for standard operation, and the SUSCLK signal can typically be ignored if not present on the module (2).

Industrial NVMe SSD Recommendations

Unfortunately, I don’t have specific validated industrial NVMe SSD models currently available in our documentation that are confirmed compatible with the Mallow carrier board beyond the ones you mentioned.

Key-M to Key-B Adapter Solutions

The documentation doesn’t provide specific validated adapter solutions for converting M.2 Key-M SSDs to work with the Mallow’s Key-B connector.

Next Steps

To get current recommendations for:

  • Currently available industrial NVMe SSDs compatible with Mallow’s M.2 Key-B interface
  • Validated Key-M to Key-B adapter solutions

I’d recommend checking the Toradex Community for the most recent compatibility discussions and testing results from other users with similar setups.

You might also want to consider testing candidate SSDs in your specific configuration, ensuring they meet your industrial temperature and reliability requirements while being compatible with the single PCIe lane provided by the Mallow carrier board (1).
