Can Canon's 70D Handle a 128 GB Memory Card?

Hello -

The price of memory cards have come down making the higher end card relatively affordable (compared to just a couple of years ago). I've purchased two 128 GB cards, the SanDisk 128 GB Extreme Pro cards, for my new Zoom F8 audio recorder. Can my happy, yet aging, Canon 70D handle such a higher end 128 GB sized card? I mainly use the camera for video and I have one project coming up which might entail a total of about 4 hours worth of shooting. (I normally set the Canon 70D to the "1280 ALL-I" setting, which generates a larger file size.) I can not find any CURRENT information regarding the maxed-sized card that the 70D can take.

Thank you. . .

Well. . .

Based on some very preliminary testing, I seem to have an answer to my question, for anyone who is interested. The 128 GB card, as described in my initial post, works. It seems to work for both for photos and videos as intended. Don't know if the full 128 GB is fully realized by the camera, though. Formatted with no content, the camera says that there are 119 GB available. Don't know where the rest of the 9 GB of card space went. I'll take it! 119 GB of available space is better than 64 GB of available space. (Glad I didn't get the 256 GB sized card, though.)

I can confirm 128 works. Bigger is better until the card corrupts and you lose everything on it. I prefer 64gb for this reason. The size discrepancy is from 10 based vs binary numbering systems.

Every single mass storage device will do this. It's a known phenomenon.

Pete and Gary - Thank you for the information, especially regarding calculating memory. I forgot that there was a different way of calculating the amount of memory which would result in a discrepancy. By the way, I did the math as mentioned in the link that Gary provided and it works out to roughly 119 GBs. 128,000,000,000 bytes divided by 1024, divided by 1024, divided by 1024 = 119.20928955078125 GBs (or roughly 119 GBs).
