SSDbasierte

SSDbasierte (SSD-based) refers to computer storage architectures and systems that rely primarily on solid-state drives instead of traditional hard disk drives. The term is used to describe configurations where SSDs provide the main storage tier, often in conjunction with or instead of HDDs, to achieve lower latency and higher throughput.

Compared with HDD-based storage, SSD-based systems offer much lower latency, higher IOPS, and faster sustained throughput. They also typically consume less energy per operation and are more resistant to physical shocks. The main drawbacks are higher cost per GB and, historically, limited endurance, though modern SSDs feature high TBW or DWPD ratings and robust wear leveling.

Common deployments include boot drives, database servers (OLTP), virtualization hosts, and caching layers. Many deployments use all-SSD storage or tiered configurations that place SSDs for hot data and HDDs for archival data. NVMe-based SSDs on PCIe provide the highest performance, while SATA-based SSDs are simpler and cheaper for less demanding workloads.

Considerations include choosing the interface (NVMe vs SATA), managing endurance and overprovisioning, enabling TRIM and garbage collection, and planning for data protection and backups. Performance gains depend on workload characteristics; workflows with random I/O and small, frequent reads/writes benefit most, while sequential workloads may not justify SSD-only costs.

SSDbasierte storage is a core feature of modern data centers, consumer devices, and cloud services seeking rapid access to data.
