Enhanced read performance on top of magnetic disk recording performance is seen as being extremely important to simultaneously achieving smaller HDDs with higher recording densities.
This technology is significantly different than magnetic disk and tape emulation since the Write Once properties of UDO are inherent to the recording surface of the media and are not a function of software or firmware controls.
At the same time, fast "discovery" of data is often a requirement to meet specific regulatory requirements and magnetic disk offers an effective way to retrieve this information in a timely manner.
