Backup storage Secondary storage 19:46:29

Storage devices Storage device or backup device is used to store data and programs that are needed to be used again and again; e.g. Floppy, hard disks, CDs are often used as backing storage as well.

19:46:29 Type of secondary storage device Magnetic storage devices Optical storage devices Semiconductor backup devices

19:46:29 Magnetic storage devices Hard disk Floppy disk Zip drive Magnetic tape

19:46:29 Hard disk

19:46:29 Hard disk Advantages Main backing storage of files and programs Can store a lot of data compared to floppy disk Can have a second hard disk as Back up storage Disadvantages Slow to access data when compared to RAM Data can be damaged if the head crashes onto the platter

19:46:29 Floppy disk

19:46:29 Floppy disk Advantages Small, thin and lightweight, so easy to carry around Can be reused. But data can not be overwritten only deleted to create space Disadvantages Can not store that much e.g one big picture will take up a lot of space of the entire floppy It is thin so it can be damaged easily

19:46:29 Zip disc/disk

19:46:29 Zip disk/disc Advantages Can hold more data tha a floppy disk Easy to carry around because of the size Disadvantages Much more expensive than a floppy You can need a special drive to read the disk

19:46:29 Magnetic Tape

19:46:29 Magnetic Tape Advantages Can store a lot of data Not easily damaged Can be used overnight to back up a system Disadvantages Takes a long time to load data onto it Have to go through the tape to get the data you want (cf serial access)

19:46:29 CD ROM CD R/W DVD Optical storage

19:46:29 CD - Rom Advantages Data can not be erased- you can not loss your data Easy to carry around Cheap to produce Can be read by a DVD drive Disadvantages Fragile Can scratch easily-this affects the data when the laser reads it Slower to access than a hard disk

19:46:29 CD - RW Advantages Data can be erased-it is possible to reuse it Data can be updated – data can be rewritable again Easy to carry around Cheap to produce Ca be read by a DVD drive Disadvantages Fragile Can scratch easily-this affects the data when the laser reads it Slower to access than a hard disk

19:46:29 DVD Advantages Can store large amount of data Does not transmit virus Good for storing films and videos The prices are getting cheaper Disadvantages Does not work in CD ROM drives More expensive than CD ROMs

19:46:29 Semiconductor/ Solid state storage devices e.g. Flash disk

19:46:29 Flash disk Data is stored by charging small- scale “batteries” on the device Most flash disks have a capacity of 256 Megabytes up to 8 Gigabytes
