Description
Every frame you shot exists nowhere until it is moved.
A CFexpress card filled with 8K raw footage is a fragile thing — a half-terabyte of irreplaceable work balanced on a PCIe lane. The 2-in-1 CFexpress Type B + SD Card Reader replaces that anxiety with certainty. USB 3.2 Gen 2 at 10Gbps translates to real-world offload speeds of 1,000MB/s — a 512GB card clears in under nine minutes. The aluminum unibody shell does more than look professional; it is a passive heatsink, drawing thermal energy away from the NVMe bridge chipset through a silicone thermal pad during sustained transfers.
What makes this reader different from the $15 adapters flooding the market is the bridge architecture. Budget readers route CFexpress through a SATA-to-USB controller — the PCIe lanes of your card get throttled to SATA-III speeds before they ever reach your computer. This reader uses a native NVMe-over-USB bridge: the PCIe lanes map directly, preserving the parallel throughput CFexpress was designed for. Dual slots mean you can ingest from a CFexpress card while backing up to an SD card simultaneously — no device swapping, no lost time.
Your footage is not safe until it exists in two places. This reader gets it there faster than anything in its class.

Application Scenarios
This reader serves the professional video and photography pipeline: wedding cinematographers offloading 8K raw from Canon R5 bodies between ceremony and reception; wildlife photographers in the field transferring thousands of 45MP bursts to a laptop SSD before the light changes; DIT technicians on commercial sets ingesting multiple camera cards simultaneously; and content creators who shoot to CFexpress for speed but archive to SD for cost. The dual-slot design eliminates the card-swapping bottleneck — both cards populate and transfer concurrently through independent bus lanes to the host device.
Frequently Asked Questions
Q: Will this reader bottleneck my CFexpress card?
A: At 10Gbps USB 3.2 Gen 2, the theoretical ceiling is 1,250MB/s. Real-world throughput with ProGrade Cobalt or Sony TOUGH cards measures 950-1,050MB/s — within 5% of the card's rated read speed. Budget SATA-bridge readers cap at 400-500MB/s, which is less than half of what CFexpress can deliver.
Q: Does it get hot during sustained transfers?
A: The aluminum shell becomes warm to the touch (40-45°C) during a 512GB continuous offload, which is normal and indicates the thermal pad is working as designed. The NVMe bridge chipset throttles at 85°C — this threshold is not reached under any realistic offload scenario.
Q: Can I use both slots simultaneously?
A: Yes. The CFexpress and SD slots operate on independent bus channels. You can transfer from both cards to separate folders on your computer at the same time — a critical feature for DIT workflows where camera A and camera B cards need to be ingested in parallel.
Q: Does it work with iPad Pro USB-C?
A: Yes. iPadOS recognizes both card slots as external volumes via the Files app. Transfer speeds are approximately 700-800MB/s on M-series iPad Pro models, limited by iPadOS file system overhead rather than the reader hardware.
Q: Is the cable replaceable?
A: Yes — the reader uses a standard USB-C female port. The included 20cm braided USB-C cable is optimized for 10Gbps; any USB 3.2 Gen 2 certified cable will perform identically.
Q: What file systems does it support?
A: The reader itself is file-system agnostic — it presents the card as a block device to the operating system. ExFAT, HFS+, APFS, and NTFS are all supported, determined by how you formatted the card in-camera or on a computer.
