diskstored

Diskstored is not a widely defined term in computing; it is often encountered as a concatenation of "disk" and "stored" or as a label within a specific project. In general usage, disk-stored data refers to information that has been written to non-volatile storage devices such as hard drives or solid-state drives, making it durable across power cycles, unlike data kept solely in RAM. Disk storage is a fundamental layer in most storage architectures, serving as the persistence medium for operating systems, databases, file systems, and applications.

Media and structures: Disk storage is provided by HDDs, SSDs, and NVMe drives. Data is organized into blocks and managed by file systems, with considerations for performance, reliability, and wear. Caching layers may keep copies in memory to reduce latency, but the canonical copy resides on disk. Reliability features include journaling, redundancy (RAID), checksums, and backups.

Context: In databases and caches, disk storage often stores persistent data or overflow pages; in file systems, all files are disk-stored. The term may also appear in configuration or documentation to indicate that a data subset is persisted rather than kept in volatile memory.
