Some operating systems (such as HPUX or Solaris) and HW platforms have constraints about the aligned memory operations. In these architectures memory operations must be byte by byte as implemented in DirectByteBuffer.

Related issue on HPUX: #5518
Related issue on Solaris: https://issues.apache.org/jira/browse/CASSANDRA-6628
