What the AI looks for in Computer Memory Card Readers
- UHS-II support
- Needed for UHS-II cards to exceed 104 MB/s (UHS-II bus up to 312 MB/s) Most cheap readers are UHS-I only.
- USB interface
- USB 3.x 5 Gbps minimum; 10 Gbps or faster for CFexpress Type B The USB link sets a hard speed ceiling.
- Connector
- Match USB-C or USB-A to your computer; avoid a chain of dongles Extra adapters add failure points and can drop the link to USB 2.0.
- Slot set
- Buy only the formats you use; single-format readers are often faster and more reliable Multi-slot combo readers often trade speed for breadth.
Brands that matter
- SanDisk: Mainstream multi-format and UHS-II readers.
- ProGrade Digital: CFexpress and UHS-II readers for professionals.

What to avoid

- Dongle hubs with a built-in reader when you need reliable large offloads
