Abstract

Selecting the correct file system is critical for space applications where risks are present. This study systematically maps and tests Ext4 versus ZFS for onboard data processing on the iX10-100 and iX5-100 payload processors. The test sets are presented along with results on several performance metrics. The conclusion is that both ZFS and Ext4 are useful, but based on certain considerations of onboard data processing, Ext4 is better than the other.
