SATA-IO Releases New DevSleep Feature for Always On Always
Connected Functionality in Ultra-Portable Computing Devices
New standard significantly lowers power consumption and extends battery life for highspeed
devices.
Beaverton, Ore. – January 05, 2012 –The Serial ATA International Organization (SATA-IO),
the industry consortium dedicated to sustaining the quality, integrity and dissemination of Serial
ATA (SATA™) technology, today announced the completion of SATA DevSleep™, a new
feature that reduces power consumption of devices. SATA DevSleep enables the development
of ultra-portable computing devices based on SATA storage solutions that consume significantly
less power than current offerings, resulting in longer battery life and enhanced ease of use.
DevSleep defines the lowest power state for SATA technology, allowing the PHY and other
circuitry to be completely powered off, unlike existing partial/slumber states, which require a
partially powered PHY. The feature allows devices to be always on and always connected
without unnecessarily reducing battery life. For example, with DevSleep an ultra-thin laptop that
would have previously needed to be put into standby to conserve battery life can now stay on
and be immediately available for use.
“Consumers want thinner, faster mobile computing products that can go a long time without
being tethered to an outlet,” said Mladen Luksic, SATA-IO president. “SATA DevSleep will
enable manufacturers to take advantage of the cost savings and performance benefits of SATA,
while addressing the needs of these low power mobile applications and enabling innovative
designs for countless future mobile devices.”
Power consumption has become an increasingly critical consideration when selecting data
storage components, as consumers are more mobile and less inclined to be “plugged in.”
SATA-IO has developed a number of power management protocols to minimize power

consumption and extend battery life in SATA devices. DevSleep expands these options by
enabling SATA technology to be implemented in ultra-portable devices without negatively
impacting battery life or limiting device response time.

The Growing SATA Ecosystem
Since its introduction in 2001, SATA technology has penetrated 99% of the PC market and
evolved to provide a variety of storage options in the battery-operated notebook computer
market. Key specifications for implementing SATA technology in this device segment include:
• SATA μSSD™: An embedded, single-chip solution that connects directly to the
motherboard to enable ultra-thin form factor devices.
• SATA Express: SATA Express is a new specification under development by SATA-IO
that combines SATA software infrastructure with the PCI Express® (PCIe®) interface to
deliver high-speed storage solutions.
