Interesting. It looks like Seagate is really looking at SSDs for the future.
“7,200 RPM spindle motors use about 46% more energy that 5,400 RPM motors and run considerably hotter as a consequence. Of course the total energy used by a hard disk drive depends upon the actual usage and power saving modes, and caching of data can reduce the energy used by a HDD in a computer system.
SSDs using flash memory consume considerably less energy when they are operating compared to HDDs. However SSDs are considerably more expensive for a given storage capacity compared to HDDs (about 10X or more in $/GB) and this has hindered wide-spread adoption of SSDs in computers. Seagate has said that they are discontinuing their 7,200 RPM 2.5-inch HDDs in favor of lower power 5,400 and hybrid HDDs.”
