Has anyone had a full on SD card corruption and lost video?

Hey all! So I’ve been curious, has anyone had any SD card failures to where they lost some or all footage? Currently I shoot on the Sony A7III and the A7IV. I utilize both a 256GB SD card, and a 128GB. I have a 64GB as my absolute backup. Someone else I worked with at one point mentioned to me that they shoot on 3-4 64GB cards, due to them not wanting the SD card containing all of the footage being ruined or corrupted, and using 3-4 cards rather than just 1.

It’s a good idea, but curious how “common” SD card failures are. I shoot around 5-10 weddings per year (side business lol) and never have had the issue, and always utilized the 256GB for every shoot.

Is this bad? Not recommended? Curious on others thoughts, thanks!

Not super common tbh, especially if you’re using solid brands, but yeah it can happen. Using one big card isn’t terrible, just kinda risky if it fails = everything gone 😬. A lot of pros split across smaller cards + dual slots for safety. Your setup’s fine, just depends how safe you wanna play it.

i had an SD card corrupt on me during a wedding. lost everything on my A camera from the pre-ceremony stuff and the entire ceremony. luckily my second shooter was good enough and I somehow still pulled a decent video together… that was a hard lesson learned, now i ALWAYS record with 2 SD’s….

Honestly one of my biggest fears. My trusty GH5 and GH5S are running 2 128gb SD cards each set to duplicate and I wouldn’t have it any other way. When shooting weddings for example, I’ll change the cards after a big event like the ceremony just in case. Backups upon backups.
