A Stochastic Analysis of Hard Disk Drives
We provide a stochastic analysis of hard disk performance, including a closed form solution for the average access time of a memory request. The model we use covers a wide range of types and applications of disks, and in particular it captures modern innovations like zone bit recording. The derivation is based on an analytical technique we call “shuffling”, which greatly simplifies the analysis...
متن کاملExploiting Commodity Hard-Disk Geometry to Efficiently Preserve Data Consistency
In the last couple of years, hard-disk technology has experienced an unjustified progressive boost of the built-in cache size, affecting both the power consumption and the reliability of stored data. Large built-in caches offer limited benefits in terms of performance with respect to the smaller ones. Moreover, they need to be kept in write-through mode to preserve data in case of a power failu...
متن کاملTransport coe cients for dense hard - disk system s
A studyofthetransportcoe cientsofasystem ofelastichard disks,based on theuseofHelfandEinstein expressions is reported. The self-di usion,the viscosity,and the heat conductivity are exam ined with averaging techniques especially appropriate for the use in event-driven m olecular dynam icsalgorithm swith periodic boundary conditions. The density and size dependence ofthe resultsis analyzed,and co...
متن کاملBoundary Dissipation in a Driven Hard Disk System
A simulation is performed aiming at checking the existence of a well defined stationary state for a two dimensional system of driven hard disks when energy dissipation takes place at the system boundaries and no bulk impurities are present. PACS: 02.70.Ns, 05.60.-k, 47.27.ek Bulk dissipation is often assumed to explain stationary states in driven systems as in the well known example of Drude’s ...
متن کاملHard Disk Controller: The Disk Drive's Brain and Body
Integration of the Hard Disk Controller (HOC) today has taken on an extensive amount of functionality. From the host interface, error correction code, disk sequencer, microprocessor(s), servo control logic, buffer controller, to the embedded memory, the HDC has become a true system on a chip. Depending on the product, embedded DRAM is used as buffering for data between the host and media and po...
