Data storage properties

Data storage properties

A data storage device is a device for recording (storing) information (data). Recording can be done using virtually any form of energy, spanning from manual muscle power in handwriting, to acoustic vibrations in phonographic recording, to electromagnetic energy modulating magnetic tape and optical discs. A storage device may hold information, process information, or both. A device that only holds information is a recording medium. Devices that process information (data storage equipment) may either access a separate portable (removable) recording medium or a permanent component to store and retrieve information.

Notebook

A laptop, also called a notebook, is a personal computer for mobile use. A laptop integrates most of the typical components of a desktop computer, including a display, a keyboard, a pointing device (a touchpad, also known as a trackpad, and/or a pointing stick) and speakers into a single unit. A laptop is powered by mains electricity via an AC adapter, and can be used away from an outlet using a rechargeable battery.

Read transfer speed

Data transfer rate or just transfer rate is the average number of bits, characters, or blocks per unit time passing between equipment in a data transmission system.

Transfer rates can serve several functions. The response time can help a network administrator pinpoint where slowdowns and potential hangups exist in a network. By analyzing data transfer rates and adjusting accordingly as a preventative measure, a system can be made more efficient and will be more prepared to handle extra bandwidth constraints in times of heavy usage.

Testing mechanisms such as fiber optic loopbacks can assist in measuring and conducting data transfer tests.

Random 4k Read

Random 4k Read IOPS:Average number of random read I/O operations per second

IOPS (Input/Output Operations Per Second, pronounced i-ops) is a common performance measurement used to benchmark computer storage devices like hard disk drives (HDD), solid state drives (SSD), and storage area networks (SAN). As with any benchmark, IOPS numbers published by storage device manufacturers do not guarantee real-world application performance.
