This article covers Lexar RW515 CFexpress Typ A Kartenleser.
Overview
The Lexar RW515 is a dedicated external card reader for CFexpress Type A cards, offering read speeds up to 900 MB/s over a USB 3.2 Gen 2 interface. It comes with a USB-C cable and a USB-C to USB-A adapter, making it compatible with both modern and older computers out of the box. For photographers and videographers using Sony α-series cameras or other CFexpress Type A devices, this reader provides a fast and affordable way to transfer large files. Positioned as a mid-range option, the RW515 delivers solid performance at a fraction of the cost of first-party readers. Its compact design and lightweight build make it easy to carry in a camera bag or pocket, ideal for on-location editing workflows.
Connectivity & Compatibility
The RW515 supports CFexpress Type A cards only — it does not read SD, microSD, or CFexpress Type B cards. The interface is USB 3.2 Gen 2 (10 Gbps) via a USB-C port. The included USB-C cable is approximately 20 cm long, keeping your desk tidy. A USB-C to USB-A adapter is also included, so you can connect to older PCs with USB-A ports without needing a separate adapter. Compatibility spans Windows, macOS, and Linux. No driver installation is required; the reader is plug-and-play. It works with any host device that supports USB Mass Storage Class.
Product Info
The Lexar RW515 (model LRW515U-RNHNG) launched in late 2023. Its street price hovers around ¥7,800, making it significantly cheaper than Sony's official CFexpress Type A reader. The manufacturer offers a 2-year warranty. In the box you get the reader, a USB-C to USB-C cable, a USB-C to USB-A adapter, and a quick-start guide. The unit weighs about 90 grams, so it's easy to toss into a bag. Market positioning is entry-to-mid-range: it lacks the rugged build of premium readers but delivers reliable performance at a budget-friendly price.
Best Use Cases
Sony α7S III, α1, FX3, and other CFexpress Type A camera users: Transferring high-resolution photos and 4K/8K video clips is dramatically faster than using SD cards. This reader can cut transfer times by a factor of 3–5 compared to a standard USB 3.0 SD reader. Laptop users with only USB-C ports: The included USB-C cable connects directly without any dongle, keeping your setup clean. The adapter also covers legacy USB-A machines. Budget-conscious creators: At roughly half the price of Sony's MRW-G2, the RW515 offers 900 MB/s read speed — plenty for most real-world workflows. If you don't need the absolute fastest write speeds or rugged metal construction, this is a smart buy. Not ideal for: Users who need to read SD cards or CFexpress Type B media, or those who require sustained write performance for heavy-duty video ingest (the RW515's write speed is not specified but likely lower than premium readers).
