Flash devices and SSDs (solid-state storage) in general are becoming
more common.

Also, backing a disk with flash.  And increasingly people will stripe,
parity, mirror or concatenate disks and flash just because it's
convenient.

could be reported.

Some aspects of flash don't fit into block devices - e.g. erase block
and write order requirements.  That's MTD stuff, not appropriate here.

But SSDs present a block device interface, and they still have
alignment characteristics for performance.  Even more important, when
combining multiple SSDs into a RAID.
