What to know before buying
Listing details to confirm
The listing is inconsistent about the 85 MB/s figure, describing it as media speed and shot/write speed, and its two dimension entries differ substantially. Treat dimensions and speed labels as unconfirmed. The 20 MB/s VPG figure is a minimum sustained write claim, while the 85 MB/s write and 120 MB/s read figures are stated as up to values. Performance and Full HD support may vary with the host device and other factors. Check that your camera accepts CompactFlash and supports the relevant UDMA mode before buying.
