Dell With Samsung Assigned Patent

Information handling system storage device
power consumption management

Dell Products, Round Rock, TX, and Samsung Electronics, Gyeonggi-Do, South Korea, have been assigned a patent (8,327,177)
developed by Munif Farhan, Round Rock, TX, Chanik Park, Gyeonggi-do,
South Korea, and Myung Hyun Jo, Gyeonggi-do, South Korea, for a "system and method for information handling system storage device power consumption management."

The abstract of the patent published by the U.S. Patent and Trademark Office states: "A
storage device, such as a HDD or SSD, reduces energy consumption by
entering a reduced power state after an inactivity time where the
inactivity time is set based upon I/O commands received at the storage
device. For example, where commands received at a storage device are
characterized in a predetermined way in terms of read commands, such as a
last received command as a read command or a ratio of read commands
versus write commands, a first inactivity time is applied, while
commands characterized in a predetermined way in terms of write commands
have a second inactivity time applied. Using a greater inactivity time
during read activities than during write activities provides improved
performance with reduced power consumption."

The patent application was filed on May 17, 2010 (12/781,090).
