Create a cheap DIY CFexpress Type B storage using an M.2 NVMe 2230 SSD drive

I recently found a way to save significantly on CFexpress Type B storage and wanted to share the details with you. While looking for storage for my new camera, I realized that CFexpress is essentially a repackaged NVMe SSD, despite the high retail price.

I successfully built a 2TB CFexpress Type B card for $314, compared to the $1,200+ retail cost (e.g. OWC Atlas Ultra 2.0TB), using the following components:

- Adapter: RIITOP CFexpress B to NVMe 2230 SSD Adapter

- SSD: Corsair MP600 Mini 2TB M.2 2230 NVMe PCIe x4 Gen4 SSD

For my Canon EOS R6 Mark III to recognize the drive, I initialized it using MBR partitioning (rather than GPT) and formatted it to exFAT. In benchmarks, the drive sustained over 1GB/sec read and write speeds, which easily exceeds the VPG-400 requirement of 400MB/sec.

I hope this DIY solution helps you get the storage you need at a much better price. Let me know if you have any questions!
