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.
