Answer / Deepak Shukla
The default block size of 128 MB in HDFS was chosen for a balance between network bandwidth, disk space utilization, and data replication. Larger blocks reduce the overhead of managing many small files and provide better disk space utilization, while smaller blocks allow for faster transfer times.
