Read/Write throughput HDFS JBOD disk

Ivoz — Tue, 21 Apr 2026 06:26:06 GMT

Hi,

regarding the disks of an HDFS datanode with for example 10 disks, what are good values for the read/write throughput for each JBOD disk? Are there any benchmarks for a production environment? (e.g. 200 MB/sec).

Thank you.
