There are certain key differences between normal file systems and HDFS (Hadoop distributed file system):

  • Normal file systems have small block size of data. (Around 512 bytes) while HDFS has larger block sizes at around 64 MB)
  • Multiple disks seek for larger files in normal file systems while in HDFS, data is read sequentially after every individual seek.
