Study Notes

Storage Devices and Media

  • Storage holds data, instructions, and information for future use
  • Storage media is the physical material where data is kept
  • A storage device is the hardware that records and retrieves items from storage media
  • Reading transfers data from storage media to memory
  • Writing transfers data from memory to storage media
  • Access time is the time it takes to find and retrieve stored data.

Hard Disks

  • Hard disks use inflexible, circular platters with magnetic particles to store data
  • Hard disks can use longitudinal or perpendicular recording methods.
  • Hard disk characteristics include capacity, platters, read/write heads, cylinders, sectors, tracks, revolutions per minute, transfer rate, and access time.
  • Formatting divides the disk into tracks and sectors for the operating system.
  • A hard disk's performance is influenced by the number of platters and access time.
  • A head crash occurs when a read/write head touches the surface of a platter.
  • A controller chip on a hard drive is called a disk controller.
  • Includes RAID, which integrates multiple hard drives, and NAS devices, which are network-connected servers.
  • External hard drives are separate from the computer.
  • Removable hard drives can be inserted and removed from a drive.

Flash Memory Storage

  • Flash memory chips are a type of solid state media.
  • Solid state drives (SSDs) do not have moving parts. Advantages include faster access time, faster transfer rates, less heat generation, and longer lifespan.
  • Memory cards are removable and used in computers, mobile devices, and card readers.
  • USB flash drives plug into a USB port.
  • ExpressCard modules are removable and used in notebooks.

Optical Discs

  • Optical discs are flat, round, portable, and made of metal, plastic, and lacquer.
  • Optical discs are read by lasers.
  • They store software, data, digital photos, movies, and music.
  • Optical discs can be read-only or rewritable.
  • Archive discs store digital images from online photo centers and have resolutions usually 7200 pixels per photo.
  • Cost is determined by the number of photos being stored.
  • Picture CDs are single-session CD-ROMs, storing digital versions of film in 1024x1536 resolution.
  • Formatting is involved for data.
  • Care is important for optical discs, avoiding exposing them to heat or sunlight, etc.
  • Common types include CD-ROM, CD-R, CD-RW, DVD-ROM, DVD-RW, DVD+RW, DVD+RAM, and Blu-ray Disc-ROM (BD-ROM).

Cloud Storage

  • Cloud storage is an internet service.
  • Users subscribe to cloud storage for various reasons (access to files, storing or accessing large files quickly, viewing time-sensitive files, creating off-site backups, and data center functions.)
  • Cloud storage providers vary, some include Dropbox, Google Drive, and Microsoft OneDrive.

Other Storage Types

  • Tape is a magnetically coated ribbon that stores data and information.
  • A tape drive reads and writes data onto tape.
  • Magnetic stripe cards are used for storing information.
  • Smart cards store data using a microprocessor embedded within the card.
  • Microfilm and microfiche store microscopic images of documents.
  • Enterprise storage stores large volumes of data for businesses and often uses special hardware setups for reliability and high performance.

Media Life Expectancy

  • Different media have varying life expectancy (e.g., magnetic disks: 3-5 years, optical discs; 5-10 years, solid state drives: 50 years, Microfilm: 100 years, etc.). These vary according to quality and manufacturer.

Putting It All Together

  • Different users have different storage needs. This section details differences for home users, small office/home office users, power users, and enterprise users.
