Transcend 300S SD Reviews

Not sure, long time to write

By Thomas
Rated 3 out of 5
Date: 2026-06-09

Bought these as they were recommended for Canon 90D, usually use Lexar or SanDisk . Shooting an airshow in RAW with HI range on shutter. Noticed long lag time to write (10 sec0nd), couldn’t review until every thing was written. Second day same configuration but 2nd card from the order. 1st attempt to shoot viewfinder went dim but shutter didn’t fire, this problem persisted throughout the day (1500 image both days) . Camera began shutting down and going into sensor cleaning mode and shutting down. Did on-site trouble shooting including shut down, removing lens, changing from battery grip to solo battery. Contacted Canon service described problem, they mentioned several issues including card but also could be a board in the camera

spare memory card important!
