Abstract
Synchronous small writes play a critical role in the reli-
ability and availability of current systems because they
are used to safely log recent state modifications and al-
low fast recovery after failures at the application and sys-
tem level. In highly demanding environments, it is typ-
ical to dedicate separate devices for the logging activ-
ity alone. Thus, systems provide adequate performance
during normal operation and extra redundancy for state
reconstruction after a failure. However, storage stacks
usually enforce page-sized granularity in their data trans-
fers from memory to disk. Under various conditions,
we experimentally show that subpage writes may lead
to storage bandwidth waste and high disk latencies. To
