This IDC study analyzes Japan's 1H05 disk storage systems market and provides a market forecast from 2005 to 2009. The market size is based on revenue, terabyte shipments, and unit shipments for 1H03-1H05. The market is analyzed by OS, installation environment (DAS/NAS/SAN), external/internal, and class. Supplier shares are calculated based on 1H04-1H05 revenue, terabyte shipments, and unit shipments.

Masaaki Moriyama, group director, Server/Storage Group, IDC Japan, comments, "It is important for suppliers to strengthen their storage-oriented businesses (such as storage consolidation and backup consolidation) that are not strongly influenced by server trends and expand the businesses in the Intel architecture (IA) sever environment in order for Japan's external disk storage systems market to return to the growth track. It is also necessary that suppliers adopt the strategy of creating demands for storage products incorporating compliance, security and other functions."
