Hero 7 Black - 128gb vs 64gb

[ Edited ]

Hey guys,

 

Just got my first GoPro cam and I have a hard time deciding on SD card.

Should I buy SanDisk Extreme 128gb (UHS-I U3 V30 A2) or SanDisk Extreme 64gb (UHS-I U3 V30 A2)?

 

I'm asking because someone on this forums wrote "they can & do go into error from time to time" about the 128gb one.

( https://community.gopro.com/t5/Cameras/Which-Capacity-of-SD-card-is-recommended-for-GoPro-Hero-7-Bla...

Is this the same issue with the 64gb? As I wan't 2x 64gb or 1x 128gb.

 

And also, the cards are A2, not A1 as the GoPro suggestions show, will this be a problem?

The A1's are for some reason more expensive over here.

 

Thansk in advance.

Hi @daniela7860,

 

I personally prefer using 64GB SD card rather that getting 128.

Hey @graytree76514

Any specific reason you like the 64gb more?

 

Weird thing is, the 128gb is 20% cheaper here.

Also, any idea about the A1 vs A2 thing?

 

Thanks!

Re: Hero 7 Black - 128gb vs 64gb

On another forum, a user explained that a different storage technique (TLC) is often used by storage manufacturers for devices 128+GB. For storage below this, they use MLC.

"MLC - Multi Level Cell name stores multi bits of data on one cell. The big advantage of this is the lower cost of manufacturing versus manufacturing SLC flash. The lower cost in flash production is generally passed onto you as the consumer, and for that reason is very popular among many brands. MLC flash is preferred for consumer SSDs for it's lower costs but the data read/write life is less in comparison to SLC at around 10,000 per cell

TLC - Triple Level Cell is the cheapest form of flash to manufacture." Read/write life cycles are considerably shorter at 3,000 to 5,000 cycles per cell." TLC is more prone to error.

Oh, and I always use 64GB cards as well.

Hey @danielr15,

 

Thank you for this informative post! I had no idea about this stuff.

I will go buy me some 64GB cards now and start enjoying my camera :)

 

 

Thanks alot!
