A friend of mine has been telling me for a few days that he has been able to use a 128GB microSD card in his Session, but won't (can't?) show me any video from said card. Everything I've read about the Hero4 Session indicates that the maximum card size memory is 64GB. Has anyone tried a 128GB card with any success, or has he just been playing an early April Fools joke on me?

128GB would be nice for some upcoming projects I'll be recording this summer (with a large capacity external battery pack hooked to it), but since I don't have any 128GB cards on hand at the moment, I want to be sure they would work before buying one or two.

Thanks in advance for any info / comments provided.

See GoPro - yes, the Hero4 Session supports 128GB.

(And for the Doc Brown fans, also supports point one twenty-five Terrabytes! )

If it does 64, it will almost certainly do 128 and higher.
To do 64 it has to support the SDXC standard, which will take you to 2TB cards. If they say 64G that probably just means that's all they've tested.

One caveat - I don't know about current models, but when I had a Hero 2, it was the absolute pickiest camera I've ever owned on SD cards. I had a dozen cards from many manufacturers, they all worked 100% fine on every camera and other device, except for the GoPro, which only worked right with 2 cards and even then did something to them that made them then not work right in many other devices.

When I asked them about it they got real snotty and said I should stop buying crappy cards. 2 of the cards that didn't work right were the exact SanDisk model that they recommended.

Wouldn't that be "one point twenty ONE JIGGAbytes"?

Yup, some devices can be picky about memory cards. I've had SanDisk compact flash cards fail in a Nikon dSLR yet work fine in other cameras. And a Class 10 SanDisk 32GB micro SD card never did work reliably in my Ion Speed Pro video camera, yet does in my tablet and smart phone. Yet a cheap, no-name 16 GB micro SD card works fine in the Ion Speed Pro, while that same type of card is rejected as "too slow" by my phone.

For what it's worth, Doc Brown would have been blown away by today's Jiggabytes of non-volatile memory too.

You can view the original non-volatile memory at the Charles River Museum (good Greater Boston Area destination). Look for the Whirlwind Core Memory plane. If Doc Brown could get his hands on one that week, each plane stored a whole 256 BITS.

The Whirlwind had a total of 32Kbits of core memory.


(ICs came in a few years later, and a decade after Marty's trip back to Doc Brown's lab, Moore postulated what is now known as Moore's Law, first doubling every year, then revised to double every 18 months a decade after that.)

my sportcam gets cranky of I remove or alter anything on the card, like deleting or renaming images. I have to leave the card fully intact until I either retire it, or reformat it
