kettapõhist

Kettapõhist is an Estonian term that translates to "disk-based" or "disc-based" in English. It refers to a method of data storage or processing that relies on physical storage media such as hard disk drives (HDDs) or solid-state drives (SSDs). The term is often used in contrast to other storage or processing paradigms, such as memory-based (in-memory) or cloud-based storage.

In computing, kettapõhist operations involve reading data from and writing data to a physical disk. This can be significantly slower than accessing data directly from RAM (random-access memory) because mechanical components or the physical interface of SSDs introduce latency. However, disk-based storage offers greater persistence and capacity compared to volatile memory.

Examples of kettapõhist systems include traditional databases that store their data files on disk, operating system file systems, and applications that save their state or data to files. While modern computing increasingly leverages in-memory databases and cloud storage solutions for speed and scalability, disk-based storage remains a fundamental component of many IT infrastructures due to its cost-effectiveness and reliability for long-term data retention. The performance of kettapõhist systems is heavily influenced by factors like disk speed, file system efficiency, and I/O operations.
