128gb micro sd
« on: August 25, 2014, 12:02:06 am »
Is a 128gb micro SD card comparable with this device?  What file system should the card be formatted in?  If so is there also a maximum number of files I can put in a folder?

64GB will definitively work. Not sure if 128GB will give you troubles. Just be sure to reformat the default exFAT partitioning as FAT32. Personally I'd use ext4 (Linux partition type) to overcome the severe limitations of FAT32.

I have not purchased anything yet.  I would still like to have a definitive answer before I purchase it.

There's no definitive answer until someone purchases one. None of the developers have one. You would have to buy one yourself to test it (which would then serve as the test, already done, for the others to look at before buying their own 128 GB cards).

Acting on purely theoretical information here:

A Microsoft Knowledge Base article suggests that Windows may be unable to operate on FAT32 volumes exeeding 127.5 GiB in size. So it may be that, while the GCW Zero can accept 128 GB cards, your computer, if running Windows, won't even be able to write to it.

However, a blog article on Dedoimedo suggests that using a Linux live CD to format a 931.5 GB hard drive to FAT32 creates a partition that can be read and written on Windows.

Regarding higher-capacity SD cards and microSD cards specifically, the host (computer or GCW Zero) must be able to accept the extended sector addresses in the SDXC (Secure Digital eXtended Capacity) protocol in order to correctly write to the card's entire capacity. A few users have tested 64 GB cards, which are officially SDXC, so 128 GB cards should work by extension.

Ultimately the decision is in your hands:
  • have a well-tested 64 GB or 32 GB card in your GCW Zero usable immediately; -or-
  • have a 128 GB which you would be the first one to test in this community. If it works, congratulations, you have a ridiculous amount of storage. If it doesn't work, you get to warn the community of this fact, and your card might get supported in a future version of upstream Linux.

The official specs says "micro SDHC up to 32 GB or micro SDXC of 64 GB" no mention of 128GB card. You should contact the gcw guy at this adress contact@gcw-zero.com before spend 100$ in a sd card who couldn't work.

The website states the following:

Quote
External storage:
micro SDHC up to 32 GB or micro SDXC of 64 GB (SDXC cards must be reformatted before use)

At the time of writing there were no 128GB SD cards available (to the developers). We were simply unable to test it.

128 GiB microSDXC cards were first released earlier this year. They were even more expensive than $100 at release:

The family of SanDisk Ultra microSD memory cards is available worldwide in capacities ranging from 8GB to 128GB with MSRPs of $29.99 to $199.99. In the U.S., the 128GB SanDisk Ultra microSDXC card is available exclusively at BestBuy.com and Amazon.com.
Emphasis mine. Source: SANDISK INTRODUCES WORLD’S HIGHEST CAPACITY microSDXC MEMORY CARD AT 128GB on sandisk.com

This explains why no developer or tester has gotten one yet.
