• What is HardDisk? – Stores data in magnetic disk like medium • Non-volatile mass storage device. • Has very high access time as compared to RAM (10-20 million ns). • Very cheap as compared to RAM and so large in capacity.
• Interface standards – IDE (Integrated Drive Electronics) The hard disk drive includes the drive controller circuitry and hence known as IDE. It can support atmost 4 devices. 16 bit interface standard; 40 pin/80 pin connector. ATA-33/66
• Interface standards contd... – SCSI (Small Computer System Interface) General pupose interface standard used for connecting many types of devices to the PC. Supports 7 to 15 different devices like hard disk, scanner, CD ROM etc. 32 bit interface standard and more expensive than IDE. Allows simultanous access for faster data transfer.
• Connecting Multiple IDE Harddisks/CD-Roms – Primary/Secondary and Master/Slave settings – Jumper settings
• Performance parameters – Rotation speed. – Average seek time.
