According to their website it enables you to boot from an SD card into Android Jelly Bean.
Has anyone tried it? Is it stable? What is the speed like? I have some concerns that running an OS from a Class 4 microSD card might be slow. Does it lose any functionality?
I originally bought the software download from N2ACards to make my own microSD - failed miserably. Probably a concern with my PC. But they refunded me. So I purchased the pre-made SD card from them with the software already loaded. It is in the mail. They offer a 30 day return. In the interim I had returned the Nook to B&N, so I will need to purchase it again. I am hoping that the store will let me install the microSD card into the shop model. But I value your input.
Running an OS requires fast reads/writes of relatively short data blocks that are typically "scatterly" placed. Media (e.g., video) content storage/retrieval on the other hand requires fast reads/writes of relatively long data blocks that are most likely contiguous. Most SDHC classes 10 and 6 are geared and hence optimized for the latter use, at the expense of the former. As such class 4 SDcards (in particular some Sandisk class 4 models) have been found to be best performer for hosting a tablet ROM. See the XDA thread http://forum.xda-developers.com/show....php?t=1005633
for more detailed performance comparison of different SDcard brands/models/classes.
Also, FWIW, outfits such as N2A do not develop the ROMs they are selling but rather just re-package the very same ROMs which their real developers make available freely on XDA forums -- and often with the clear stipulation "do not sell pre-made sdcard" -- with the convenience of a ready-to-use card and purported "technical support". As such, whatever outstanding issues with beta versions of these free ROMs are likely to be found in the versions on the pre-made cards that these outfits sell.
