THE PRACTICAL PERSPECTIVE
Overall review.
Check your recording mode
Look up the card requirements for the camera and resolution you actually use. V30 specifies a minimum sustained write rate of 30MB/s under the relevant conditions. A camera may require a higher class for some modes.
Match the reader to the workflow
The advertised peak is a read speed. Offload times depend on the card reader, USB connection and destination drive. If your laptop has a full-size SD slot, allow for a compatible adapter or separate microSD reader.
Keep a second copy
Copy footage to another drive before reusing the card. A bigger card gives you more room between transfers, but it still holds only one copy of each clip.
