Managing hard-disk PCs in the introductory laboratory

A hard disk is a high-capacity, high-speed rotational storage device. Hard disks are sometimes called fixed disks because they usually cannot be removed from the computer. This nomenclature is somewhat outdated now that removable hard disk storage ...

This paper presents a novel disk storage architecture called DCD, Disk Caching Disk, for the purpose of optimizing I/O performance. The main idea of the DCD is to use a small log disk, referred to as cache-disk, as a secondary disk cache to optimize ...

Our objective is to improve disk I/O performance in multi-disk systems supporting multiple concurrent users, such as file servers, database servers, and email servers. In such systems, many disk reads are absorbed by large in-memory buffers, and so disk ...
