Still, managing data on flash is still quite tricky. That's why Dirbaio and I both wrote a higher level crate to deal with it.... Yes, I'm familiar with this matter and have researched sequential-storage solutions. The core issue I faced involved handling large volumes of data that share a uniform structure (similar to database tables), but with relatively few records. The existing libraries created headers and metadata that consumed too much memory space - a critical limitation given my constrained memory resources. To address this, I developed an alternative algorithm specifically designed for structured, uniform data. My solution eliminates headers and metadata entirely, and instead of traditional indexing, it uses lightweight runtime calculations to directly access target data. This approach delivers exceptional speed while consuming absolutely no additional storage space. This storage method proves ideal when you need database-like organization with fixed-size records - precisely what my project requires. I believe other developers might benefit from similar solutions in certain projects. That said, sequential-storage remains an excellent choice for dynamic data storage scenarios where flexibility is more important than space optimization.
