While the actual numbers will vary between different drives, this gives a relative idea on the times taken. The following shows the relative time (in milliseconds) involved in these operations, based on the theoretical specification of the SATA drive used. The data is then read and optionally placed in OS file system cache, and copied to the application buffer. Since the angular velocity of the disk is constant, more data can be read from the outermost perimeter of the disk than the inner perimeter in a single rotation.Д®very time a read request is placed by an application, the disk may have to be spun-up first, and the read/write head must be positioned at the appropriate sector. Furthermore, the actual throughput of the system is also dependent on the physical location of the data on the drive. Seek time and rotational latency relates to the time taken by the disk to position the read/write head from its current track to the track and sector where data is to be read/written. RPM is the rate at which a hard drive spins and directly impacts the performance. The performance of a hard disk is related to various factors such as RPM, seek time, rotational latency, and the sustainable transfer rate. Multiple sectors are grouped into clusters, which the operating system efficiently uses to store and manage all files. A hard drive is organized into multiple sectors which are the most basic addressable blocks of storage.

The sample code provided with this whitepaper consists of an in-house multithreaded prototype to perform bitmap to JPEG conversion, and APIs to detect a fragmented file and defragment it utilizing Native Command Queuing using async I/O.Д®xamining methodologies to optimize powerДЇirst, letвЂ™s take a look at some of the characteristics of a hard drive. This paper also provides guidelines on optimizing the power during disk I/O in various usage models along with the power impact. In this whitepaper, we shall analyze the power characteristics of the disk during sequential/random reads and native command queuing, and provide an analysis on file fragmentation and disk thrashing.

Set of driver and libraries which access/reads the energy MSR from the processor and then post process the processor energy counter raw data to calculate the power usage in watts and processor frequency IntelВ® Power Gadget consist of the following components It lets you log the power and frequency measurements and save it in a csv format. Provides processor power (Watts) and frequency (MHz) in real-time via graph displayed by the gadget. It is a simple and easy way to monitor energy usage of the processor. The 2nd Generation IntelВ® Coreв„ў processor family (codename Sandy Bridge) offers an energy counter to estimate the power drawn by the processor and IntelВ® Power Gadget is utilizing this energy counter and provides an easy way to estimate power consumption of the processor without cumbersome setup.Д¬ommon use of IntelВ® Power Gadget is via WindowsВ® 7 sidebar gadget. It is always a challenge to measure power usage of the processor by software which usually requires special purpose tools or instrumentation along with third party equipment.
