Well ... you *might* create a big file on the filesystem, then use
losetup to bind it to a block device, and *then* use hdparm on that
loopback device. ;-)

Opinion ... I've never found any use for filesystem performance
measurement in audio applications ... it has never been the critical
path for me. As soon as the total data flow approaches the limit
imposed by the filesystem, then anything can cause a pause ... even a
disk drive thermal recalibration or a response to excessive vibration.
Such things cause a momentary delay, and if I'm trying to use the disk
the filesystem I'm using won't matter at all.
