 Because _etcd_ writes data to disk and persists proposals on disk, its performance depends on disk performance. Although _etcd_ is not particularly I/O intensive, it requires a low latency block device for optimal performance and stability.
 
 * In terms of latency, run etcd on top of a block device that can write at least 50 IOPS of 8000 bytes long sequentially.
-* That is, with a latency of 10ms, keep in mind that uses fdatasync to synchronize each write in the WAL.
