My understanding is that XFS is well-suited for handling a large number of threads trying to access the disk path simultaneously (parallelized access via allocation groups ensures multiple threads can perform I/O simultaneously on the same volume). This is constantly the case on an SMS/MDS with incoming firewall logs being written, SOLR log indexing, SmartEvent correlation, security policy configuration-related postgres database operations, etc. XFS is also optimized for working with very large files (like postgres database extents) and works especially well with SSDs which are starting to become more and more common on Check Point appliances.
It is doubtful that a single dd I/O operation will reflect these XFS advantages.
