This is where ZFS could be a good thing.  ZFS doesn't generally do small,
random writes.  If we get 15 random write iops at 128kBytes, then it
is more reasonable.

They also list the number at 512kB, and it is still only 16 IOPS.
This is probably an artifact of striping across a large number of
flash chips, each of which has a large page size.  It is unknown how
large a transfer is required to actually reach that respectable
sequential write performance, though it probably won't happen often,
if at all.

They should send me one so that I can experiment :-)
