The following is the documentation draft for a proposed new PINE64 storage product, PineFlash. As such, PineFlash is proposed by the community and, as of April 2021, is '''neither endorsed nor acknowledged''' by PINE64 as a possible new official PINE64 product. This content is the result of initial discussions about this storage device, documented in [https://forum.pine64.org/showthread.php?tid=13301 this forum thread]. | |||

The aim of this project is to create | The aim of this project is to create an open-hardware USB flash drive, hence the name ''PineFlash'', which can act as the basis of future projects in the area of open storage. An open-hardware flash device with open-source firmware would allow the community to address storage safety and information security. Additionally, issues such as speed, functionality and compatibility could also be addressed. | ||
