Fujifilm LTO Ultrium 4 media is the first midrange data storage product to use Fujifilm's proprietary NANOCUBIC thin-film coating process to reach the higher capacity and quality levels currently only found in enterprise-class systems. LTO Ultrium 4 is the second generation in the LTO Ultrium Roadmap to support WORM (Write Once Read Many) functionality. The LTO 4 specifications include the ability for WORM enabled and non-WORM enabled drives to co-exist and provides users with very cost effective means of storing data in a non-erasable, non-writeable format. |
