Frequently Asked Questions
How does the write-protect switch work?
It is a physical hardware switch, not software. Flip it to 'Write Check' and the card becomes read-only at the device level. No accidental formatting possible, even if someone clicks delete.
Does the write-protect switch work on all card types?
Yes. Works on SD, SDHC, SDXC, CFexpress, and microSD. Physical write-protection is universal across card standards.
What transfer speeds does the PRO-READER achieve?
Up to 10Gbps (USB-C 3.2 Gen 2). Real-world speeds are 280-312 MB/s with UHS-II cards. This is the same speed as compact USB-C readers, so the PRO-READER is chosen for safety, not speed.
