Compare the Lexar RW510 CFexpress Type B reader and the WF730 CFexpress 4.0 Type A reader by card format, workflow and budget so you buy the right one.
Quick answer
Buy the Lexar RW510 if your camera records to CFexpress Type B cards; buy the Lexar WF730 if you shoot on CFexpress 4.0 Type A media and want a reader built for the Lexar Professional Workflow system. The card format in your camera decides this, not the price.
The card format is the only real decision
These two readers are not interchangeable. The RW510 accepts only CFexpress Type B cards, while the WF730 is dedicated to CFexpress 4.0 Type A. No adapter or firmware update changes that, so check the card slot label on your camera body or the card itself before comparing anything else.
If you already own a mix of Type A and Type B media, you will eventually need one reader per format. Start with the reader that matches the cards you shoot most, then add the second when the other format becomes part of your regular workflow.
Speed claims only matter if the rest of the chain keeps up
The RW510 uses a USB 3.2 Gen 2 interface rated up to 10 Gbps, which is the practical ceiling for most Type B offloads today. The WF730 is positioned for CFexpress 4.0 Type A, a newer generation of card, but a fast reader still depends on a fast card, a suitable cable and a host port that can sustain the throughput.
In practice, a Gen 2 reader on an older USB 3.0 port will run at the slower port speed. Before paying for speed, confirm your computer or hub actually offers a Gen 2-capable USB-C port.
Workflow integration is the WF730's real differentiator
The WF730 is designed to slot into the Lexar Professional Workflow ecosystem, which matters if you already organize offloads around that modular system. The RW510 is a standalone USB-C reader with a simpler, lower-cost role.
If you never plan to use the Workflow system, that integration adds little value for you, and the RW510's narrower focus is easier to justify.
Decision rules for choosing your reader
- Match the card in your camera: Check whether your camera uses CFexpress Type A or Type B. Type B points to the RW510; CFexpress 4.0 Type A points to the WF730. Write the format on your card wallet so you never buy the wrong reader by mistake.
- Confirm your host port: The RW510's USB 3.2 Gen 2 interface reaches its 10 Gbps rating only on a compatible port. Verify your computer or hub before expecting full speed.
- Decide on the Workflow ecosystem: Pick the WF730 if you already use or plan to use Lexar Professional Workflow. Otherwise the RW510 covers Type B offloads with a simpler setup.
- Budget for one reader per format: If you shoot both Type A and Type B, plan to own both readers rather than expecting one unit to cover both. Label each reader so you grab the right one on a shoot day.
