*Blocks are the smallest continous locations in your hard drive where data is stored. HDFS stores each files as blocks, and distribute it across hadoop cluster. These data blocks serve many advantages to HDFS. The individual data from each user is stored in contigous locations and in the similar way each user details are stored.
