Sector

  • Minimum amount of data that can be read or written to HD
  • Traditionally 512Bytes, now different options are there
  • Optimal sector size should be used
    • example if database that writes 8,192-byte records, then sector size should be configured as 8KB, so that complete entries are written in one allocation unit
    • If size is 4 KB then record gets split
