The implementation of nanoimprint lithography for the fabrication of patterned magnetic media
… a major catalyst in increasing the popularity of hard drives. In 2002, two exabytes of original information was stored on hard drives. This is ten times the amount of all printed material in the world if it were converted to electronic files. To keep up with this demand, the capacity of hard …

Monitoring PC Hardware Sounds in Linux Systems Using the Daubechies D4 Wavelet.
… parameters such as voltage, temperature, and hard drive status in order to anticipate possible system failure. However, one modality for PC monitoring that has been underutilized is sound. The application described here uses wavelet theory to analyze sounds produced by PC hard drives during …

Simulating raid storage systems for performance analysis
… fault-tolerant storage solution using commodity hard-drives. RAID storage systems have recently surged in popularity amongst enterprise clients, as they provide economical, scalable, high-performance solutions for their storage requirements. The performance of RAID systems is negatively affected …

Cheetah: An Economical Distributed RAM Drive
Current hard drive technology shows a widening gap between the ability to store vast amounts of data and the ability to process. To overcome the problems of this secular trend, we explore the use of available distributed RAM resources to effectively replace a mechanical hard drive. The essential …

Role of bit patterned media in future of hard disk drives
The hard disk industry has traditionally stayed competitive by competing on the means of price alone by cutting down aggressively on cost via increase of areal density. Continuing increases in the areal density of hard disk drives will be limited by thermal instability of the thin film medium and …

Automated Syndromic Surveillance using Intelligent Mobile Agents
… surveillance system that will utilize the hard drives and computer processing unit (CPU) power of the hosts on the agent network where the syndromic information is located. This thesis proposes the design of a mobile agent-based syndromic surveillance system and an agent decision model for …

The role of copper on stress evolution and chemical ordering in iron-copper-platinum thin films
… annealing lowers the areal density in computer hard drives. Multiple paths have been proposed to lower the ordering temperature in order to decrease the grain growth. Ternary additions show promise as a way to lower the ordering temperature and decrease the grain growth. Though multiple studies …

Exploring the Extent to Which the Utilization of Technology Has Facilitated the Increased Possession of Online Child Pornography over Time
… of child pornography over time. Specifically, hard drives, removable media, peer-to-peer, and encryption were all identified as having statistically significant relationships to either increased image/video amount or increased usage of that particular technology over time. This study concludes …

Probabilistic Approach to Avoid Uncorrectable Bit Errors in Storage Systems
… by analyzing 150M daily SMART logs from 143K hard drives collected over the period of five years. The models achieve up-to 97% accuracy in uncorrectable bit error prediction while keeping false positive rates less than 3%. We further introduce two use cases to utilize highly accurate error …

Modelling tribology of slider and disk in a computer hard drive system
… tribology are increasingly important in computer hard drives as slider flying heights are becoming lower and disk protective coatings thinner to minimise spacing loss and allow higher areal density. Friction, stiction and wear between the slider and disk in a hard drive were studied using …

An Interactive Visualization Model for Analyzing Data Storage System Workloads
<p>The performance of hard disks has become increasingly important as the volume of data storage increases. At the bottom level of large-scale storage networks is the hard disk. Despite the importance of hard drives in a storage network, it is often difficult to analyze the performance of hard …

On the use of NAND flash memory in high-performance relational databases
… have released IDE-compatible NAND flash-based drives in sizes up to 64 GB at reasonable (sub-$1000) prices. Because flash is significantly more durable than mechanical hard drives and requires considerably less energy, there is some speculation that large data centers will adopt these devices. …

Context-Aware Resource Management
… Network Interface Controllers/Cards (WNICs) and hard drives. The Interaction Aware Prediction (IAP) system for WNICs is evaluated showing that the available power modes can be effectively managed to provide energy efficiency while maintaining performance. Similarly, the Interaction Aware Spin-up …
