Advanced drive technology
The Hitachi Ultrastar 15K73 is the 3rd
generation of 15,000 RPM enterprise-
class hard drives from Hitachi. Leveraging
award-winning technologies that have
generated proven quality and high-perfor-
mance, the Ultrastar 15K73 incorporates
Fluid Dynamic Bearing motors (FDB)
to contribute to increased capacity by
enabling high-track density through a
more precise position of the head. AFC
Media, also known as “pixie dust”, is an
industry-first in 15,000 RPM enterprise-
class hard drives, enabling higher areal
densities by improving thermal stability,
which in turn, maintains data integrity.
