Applications
The SiI5734 is a low-cost, single chip solution for single-drive external enclosures and
external backup drives. This SteelVine Storage Processor has two 3 Gbps eSATA Gen2m
device ports, one 3 Gbps eSATA host port and one USB 2.0 host port. The SiI5734 fea-
tures proprietary eSATA-based capacity expansion, which allows users to easily grow the
capacity of an existing SteelVine enabled device by adding additional drives. The new
drives will appear to the host system as additional space in the existing SteelVine volume.

The SiI5734 SteelVine Storage Processor allows
manufacturers to build a range of internal and
external single-drive storage solutions that sup-
port both USB and eSATA Gen2m, the fastest
interface for consumer storage. Other features of
the SiI5734 include drive locking, single-button
backup and support for advanced RAID modes.
Extensive software developer kits are available
from Silicon Image to support development and
simplify product differentiation.
The SiI5734 also features drive locking, which
helps protect users' data by allowing them to
password lock directly attached and cascaded
drives. If a locked drive is detached from its
assigned computer or cascade, the data on the
drive will be inaccessible until it is reconnected
and unlocked with the user supplied password.
Single-button backup through third-party appli-
cations is also supported.
