There are many cases where Yaffs is used in telecommunications infrastructure such as trunking radio, telephone exchanges and network infrastructure. Yaffs is specifically designed to cope well with power loss situations. One of the key features is that Yaffs is log structured. That means Yaffs does not have allocation tables etc stored in the media. If they are not stored, they can't be corrupted. Yaffs routinely undergoes power fail test simulations to check the power fail robustness. -- Charles
