depends on block device performance benchmarking - fio preferably or bonnie++ as fallback
/sys/block/sdX/queue/rotational could be used as hint (SSD or spinning disk)
right now only filesystems get benchmarked, not block devices e.g. for a VG, each PV, or at least all different kind of PVs should be benchmarked. Based on thic benchmark information, one could estimate the latency after the cache is created.
to improve IO of some virtual storage devices (where needed)
