In spite of the ever increasing speeds and capacities, we still have rotating CATEGORIES platters being accessed through mechanical heads. OPINIONS FEATURES The major breakthroughs have been in interfaces, REAL WORLD such as SATA (Serial ATA). These have provided a COMPUTING dedicated link between the drive and the controller with a smaller cable, and in the process MIND YOUR BUSINESS relegated ribbon cables to the technological graveyard where they are now fulfilling the role of TECH SUPPORT keeping laserdiscs and old iMacs company. HEADLINES Product brief July The same technology has made its way into the enterprise market, where the old SCSI standard has been superseded with SAS (Serially Attached SCSI). It provides a physically Feeling Good similar connection to SATA, however it still uses all the tried and true SCSI commands and Call of Duty 4: Modern Warfare adds extra features such as more bandwidth, redundant controllers and better management hands-on features. Half-baked Blackberry Fundamentally SAS takes the bulletproof (thousands of network engineers just cried out in Closing Pandora’s box pain when they read the word “bulletproof” in the context of hard drives) design of SCSI and delivers it through a similar interface to SATA.

The Onnto DataTale 2-bay RAID System, sold by Storage Depot, is one product however that might be right up there at the top of that list. The Onnto DataTale 2-bay RAID System is designed to house two 3.5in hard disks and is attractive enough to sit handsomely on the desk. It connects by one of four standard desktop protocols. In order of speed these are: USB 2.0, FireWire 400, FireWire 800 and eSATA. As a two-drive system, we’re presented with a few options how to configure those disks. You can set to RAID 0, which combines the capacity of two drives and increases performance by striping data between the disks; RAID 1, which mirrors data between two disk for increased protection in case one disk fails; or JBOD (just a bunch of disks) which combines the drives with no additional speed or security failsafes, and lets you access the disks as two separate volumes.

  • Benchmarked Hard Disk Drive Performance Characterization and Optimization Based on Design of Experiments Techniques
    BENCHMARKED HARD DISK DRIVE PERFORMANCE CHARACTERIZATION AND OPTIMIZATION BASED ON DESIGN OF EXPERIMENTS TECHNIQUES A Thesis presented to the Faculty of California Polytechnic State University, San Luis Obispo In Partial Fulfillment of the Requirements for the Degree Master of Science in Electrical Engineering by Yu-wei Lin June 2010 c 2010 Yu-wei Lin ALL RIGHTS RESERVED ii COMMITTEE MEMBERSHIP TITLE: Benchmarked hard disk drive performance characterization and optimization based on Design of Experiments techniques AUTHOR: Yu-wei Lin DATE SUBMITTED: June 2010 COMMITTEE CHAIR: John Y. Oliver, Assistant Professor COMMITTEE MEMBER: Jianbiao Pan, Associate Professor COMMITTEE MEMBER: James G. Harris, Professor Emeritus iii Abstract Benchmarked hard disk drive performance characterization and optimization based on Design of Experiments techniques Yu-wei Lin This paper describes an experimental study offered by Designs of Experiments (DOE) within the defined factor domains to evaluate the factor effects of simulta- neous characteristics on the benchmarked hard disk drive performance by propos- ing well-organized statistical models for optimizations. The numerical relations of the obtained models permit to predict the behaviors of benchmarked disk per- formances as functions of significant factors to optimize relevant criteria based on the needs. The experimental data sets were validated to be in satisfying agreement with predicted values by analyzing the response surface plots, contour plots, model equations, and optimization plots. The adequacy of the model equations were verified effectively by a prior generation disk drive within the same model family. The retained solutions for potential industrializations were the concluded response surface models of benchmarked disk performance optimizations. The comprehensive benchmarked performance modeling procedure for hard disk drives not only saves experimental costs on physical modeling but also leads to hard-to-find quality improvement solutions to manufacturing decisions.

MOUNTING A WINDOWS SOFTWARE RAID AS A VIRTUAL DISK BY DANIEL N. DUCHARME A THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF SCIENCE IN COMPUTER SCIENCE UNIVERSITY OF RHODE ISLAND 2012 MASTER OF SCIENCE THESIS OF DANIEL N. DUCHARME APPROVED: Thesis Committee: Major Professor Dr. Victor Fay-Wolfe Dr. Gerard Baudet Dr. Qing Yang Nasser H. Zawia DEAN OF THE GRADUATE SCHOOL UNIVERSITY OF RHODE ISLAND 2012 ABSTRACT When an investigator attempts to bring a write blocked Windows dynamic disk online, Windows will refuse to mount it. This forces investigators to use the few tools that have built-in support for dealing with the RAID or to image the partition, and then mount the image. While imaging did not use to be an issue, with the rising sizes of disks available at low cost, it is becoming prohibitively expensive to image every software RAID. The solution is to mount the RAID through the use of a driver as a virtual disk.
