There is no reclamation on a diskpool. Over time the deletion of (very) small
data blocks will make it heavily fragmented which will definitely impact you
performance...

I believe a fileclass storagepool is better suited for this kind of "permanent"
storage on disk.
A diskpool should be used for things such as disk between the backup client and
tape for temporary random I/O storage that can handle an unlimited amount of
sessions.
A fileclass storagepool is better suited for long term storage.
I create a diskpool for VE metadata when using dedup on the filepool and use
fileclass storagepools for permanent storage on disk with or without
deduplication.
Are you planning on using deduplication on disk?
