Compare Lexar CFexpress Type B and Micro SD memory cards for cameras. Find out which card fits your workflow, from 8K video to everyday shooting.
Quick answer
For cinema-quality 8K RAW video and high-speed burst shooting, choose a Lexar CFexpress Type B card like the Gold Series. For everyday 4K video, action cams, or drones, a Lexar Micro SD card like the Silver Plus delivers reliable performance at a lower cost.
Speed and workflow differences
CFexpress Type B cards are built for professional cameras that demand sustained write speeds above 1000 MB/s. The Lexar Professional Gold Series CFexpress 2.0 Type B card reaches up to 1750 MB/s read and 1500 MB/s write, which handles 8K RAW video without dropped frames. Micro SD cards top out around 205 MB/s read and 150 MB/s write, which is plenty for 4K at 60fps but not enough for the highest bitrate cinema formats.
The physical size also matters. CFexpress Type B cards are larger and fit only in cameras with a dedicated slot. Micro SD cards are tiny and, with the included SD adapter, work in most consumer cameras, laptops, and handheld devices. If you swap cards between a mirrorless camera and a tablet, Micro SD gives you that flexibility.
Capacity and value trade-off
At the 128GB level, the Lexar CFexpress Gold Series costs about $112, while the Lexar Silver Plus Micro SD at 256GB costs around $75. You get more storage per dollar with Micro SD, but you sacrifice speed. For a hybrid shooter who mixes photo bursts and 4K video, the Micro SD card offers a sensible balance. For a dedicated video pro who needs every frame of 8K RAW, the CFexpress card is the only reliable option.
Trade-offs at a glance
- Speed vs cost: CFexpress Type B cards cost more per GB but offer 10x the sustained write speed needed for 8K RAW. Micro SD cards are far cheaper per GB but cap out at 4K 60fps.
- Durability and size: CFexpress cards are physically larger and fit fewer devices. Micro SD cards are tiny, waterproof, temperature-proof, and x-ray-proof, making them better for travel and swapping between devices.
- Camera compatibility: CFexpress Type B cards require a dedicated slot found in high-end mirrorless and cinema cameras. Micro SD cards with an SD adapter work in almost any consumer camera, laptop, or tablet. Check your camera manual for supported card formats before buying.
