solidstatemedier

Solidstatemedier, a term used in several European languages, refers to storage media that store data in solid-state electronic components with no moving parts. They contrast with magnetic hard disks and optical media. Solid-state storage retains data in nonvolatile memory, allowing operation without mechanical components.

The core technologies include NAND and NOR flash memory, phase-change memory, magnetoresistive RAM (MRAM), and ferroelectric RAM (FRAM). The most common form is NAND flash used in solid-state drives (SSDs), USB drives, and memory cards; newer 3D NAND stacks cells to increase capacity and reduce cost per bit. Controllers and interfaces (such as SATA, PCIe NVMe, eMMC, and UFS) manage data transfer, wear leveling, and error correction.

Advantages of solidstatemedier include high read/write speeds, low latency, no moving parts, robustness to physical shocks, and lower energy consumption in idle states. Limitations include higher cost per gigabyte compared with some magnetic media, wear-related write endurance for certain flash types, data retention concerns under long-term storage at extreme temperatures, and a reliance on firmware features such as wear leveling and error correction. They are widely used in consumer electronics, laptops, smartphones, data centers, and embedded systems.

Market and technology trends focus on increasing memory density, improving endurance and reliability, reducing power consumption, and expanding nonvolatile memory types, such as MRAM and PCM, to broaden application areas. The term solidstatemedier encompasses a range of nonvolatile storage solutions that depend on solid-state electronics rather than moving parts.
