SATA II is the next set of
SATA specifications
after the initial SATA specification was written. SATA II specifications provide
additional enhancements to SATA, delivered in increments. The first increment,
called .SATA II: Extensions to SATA 1.0. was released in 2002 and focused on the
immediate needs for the server and network storage segments. Additional
increments of the specification will focus on enhanced cabling, fan-out and
failover capabilities and next generation signaling speeds. In spring 2003, two
incremental developments were announced: a SATA II Port Multiplier specification
release candidate and the completion and pending adoption of the SATA II Cables
and Connectors Volume 1 specification.
