Hard Drives

  1. IDE - Integrated Drive Electronics
    • mass storage device, controller integrated into the disk
    • 1 Controller 4 pins, 2 devices
    • Speed - 3 MBs
  2. EIDE- Enhanced Integrated Drive Electronics
    • newer version of IDE
    • data rate 4-16.6 MBps
    • up to 8GB of storage replacing SCIS
  3. ATA
    Known also as IDE, supports one or two hard drives, a 16-bit interface and PIO modes 0, 1 and 2.
  4. ATA-2
    Supports faster PIO modes (3 and 4) and multiword DMA modes (1 and 2). Also supports logical block addressing (LBA) and block transfers. ATA-2 is marketed as Fast ATA and Enhanced IDE (EIDE
  5. ATA/33
    Also called Ultra-DMA/2 , and DMA-33, supports multiword DMA mode 3 running at 33 MBps.
  6. ATA/100
    or ultra DMA/5
  7. ATA/66
    or Ultra-DMA/4 A new version of ATA proposed by Quantum Corporation, and supported by Intel, that will double ATA's throughput to 66 MBps. Other ATA supports speeds of 100 and 133MB/s
  8. ATA/133
    aka Ultra-DMA/6 currently the fastest IDE hard drive in the market
  9. Platter
    The actual fixed disk within the hard disk drive. There can be several platters within the hard drive
  10. Heads
    Each side of platter
  11. Tracks
    Large sections that completely circle the platter
  12. Sector
    Pie sections on the track
  13. Cluster
    The smallest unit of measurement that a hard disk will read
  14. Clylinder
    Tracks of the same diameter on each platter
