Storage Devices And Backup Media

1. Storage Devices And Backup Media Briona Allen, Christian Parker, & Shanita Williams

2. Storage Devices • Holds media that needs to be accessed • Holds files that the system needs to operate • Holds data that needs to be saved

3. FDD(Floppy Disk Drives) • Rapidly becoming obsolete but still found in legacy applications • Most recent configuration accepted a removable 3 1/2" disk with a storage capacity of 1.44 MB • Traditionally assigned drive letters A: and B: • Power supplied through a 4-pin Mini power Connector (Molex) • Data transferred to motherboard through a 34-pin keyed ribbon cable

5. TEST YOUR KNOWLEDGE • What kind of power connector does a floppy drive use? • A. AT Power Connector • B. ATX Power Connector • C. Molex Power Connector • D.Mini-molex power Connector

6. HDD • Typically mounted inside the computer • Provides permanent storage and quick access • Stores information either on small disks called platters or in integrated memory chips • Read and write operations are managed by the controller • Data is transferred to and from the motherboard by the host adapter

8. Test Your Knowledge • Where does the HDD store information: • A.) The Motherboard • B.) Small disks called platters • C.)Host Adapter • D.)None of the Above

9. Magnetic Hard Drives A magnetic disk's medium contains iron particles, which can be polarized—given a magnetic charge—in one of two directions. • Each particle's direction represents a 1 (on) or 0 (off), representing each bit of data that the CPU can recognize. • A disk drive uses read/write heads containing electromagnets to create magnetic charges on the medium

10. Primary Magnetic Storage Devices Primary Magnetic Storage Devices: • Diskettes (floppy disks) • Hard disks • High-capacity floppy disks • Disk cartridges • Magnetic tape

11. Advantages of Magnetic Hard Drive • Cost Less • Higher number of writes/erase cycles • Higher write speeds

12. Solid State Drives • Uses memory chips to store data • Contains no moving parts • Quieter • Resistant to shock and vibration • Faster read/write speeds • Expensive • Requires constant power source

13. Advantages of Solid State Drives • Faster Startup • Higher read speeds • Lower power consumption • Less heat generated • Less risk of failure

14. How To Install A Solid State Drive • http://www.youtube.com/watch?v=yYbWx74Vgmo

15. Test Your Knowledge Which of the following is not true when discussing the advantages of a solid state drive over a magnetic drive? • A.) Faster Startup • B.)Faster Radom Access for reading • C.) Quieter • D.)Unlimited Read and Writes

16. Optical Drives Data is recorded to this type of media by stamping irregularities onto the surface of the disc, or "burned" into it using a laser, in a spiral pattern that runs from the inside to the outside of the disk. • Compact Discs (CD), • Digital Versatile Discs (DVD) • Blu-Ray discs

17. Compact Discs CDUsed for digital data storage • formats include read-only (CD-ROM), write-once audio and data storage (CD-R), and rewritable media (CD-RW). • Storage capacity ranges from 650-900MB.

18. DVD • DVD discs can be single or double sided. • each DVD side may contain a second invisible "layer" to increase the disc's storage capacity. • 4.7GB capacity(single-sided/single-layer) • 8.5GB capacity (single-sided/double-layer) • 9.4GB capacity (double-sided/single-layer) • 17.1GB capacity (double-sided/double-layer)

19. Blue RAY • High-density optical disc created with a blue laser • Used to store HD video and large amounts of data • 25-50GB storage capacity single-layer • 50-100GB storage capacity dual-layer

20. Test Your Knowledge Which has the greatest storage capacity? • A.)CD • B.)CD-RW • C.)DVD • D.)Blu-Ray

21. Removable Storage • Tape drive • Can be installed internally or externally • Uses either digital or analog magnetic tape • 100GB capacity / 200GB compressed • Slower than most medium • Primarily used for archives Solid state • Thumb Drive: Also known as a jump drive or flash drive, a convenient means for data transfer quickly replacing the traditional floppy disk drive • SD cards: small memory cards used in electronic devices

22. Test Your Knowledge • Where can you find a Standard SD memory card? • A.A cellular/smart phone • B.A digital camera • C.A PDA • D. All of the options provided are correct

23. External Hard Drive • External hard drives store your valuable data and add a considerable level of safety and security. • Provides portable storage with popular interfaces of USB and FireWire. • Some are available with an eSATA or SCSI interface • some still require additional power sources.

24. Hot Swappable Devices And Non-Hot Swappable Devices Hot swappable devices can be added or removed from your computer without having to reboot. Examples: • USB Devices • Keyboard • Mouse • Thumb Drives • Some SATA Hard Drives Devices that require rebooting or need to have drivers installed to operate are considered non-hot swappable • Examples: • internal hard drive 

25. Test Your Knowledge • What do you call the technology that allows you to connect and disconnect a device to a computer while the computer is running? • A. Hot-swappable • B. Power-charged • C. Plug and play • D. Compact
