Global demand for storage capacity continues to rocket, with growth of nearly 49 per cent year over year to 175.6PB shipped during the first quarter of 2003.
But according to analyst firm IDC, demand has not been matched by increases in worldwide revenues which, at $4.8bn in the first quarter of 2003, were one per cent lower than the first quarter of 2002.
This slight year-over-year decline was better than the eight per cent decline for the last three months of 2002.
While the overall market headed towards stability, disk storage systems revenue grew nearly 14 per cent year over year, thanks to strong sales in the Open storage area network (San) market.
"First-quarter results continue to illustrate increased customer adoption of network storage systems [Network attached storage (Nas) and Open San]," said Charlotte Rancourt, research director at IDC.
"Network storage for the first time represents more than half - 53 per cent revenue share - of the total external disk storage systems market."
In the first quarter, Hewlett Packard (HP) led the total disk storage system market with 26.3 per cent revenue share, followed by IBM and EMC with 19.1 per cent and 11.7 per cent respectively.
Dell posted the strongest year-over-year growth during the first quarter among the top five vendors, with a 37.5 per cent rise.
In the total external disk storage system market, revenue decreased 2.7 per cent year over year in the first quarter. HP maintained its number one position with 19.5 per cent share, followed by EMC with 17.4 per cent.
EMC continues to maintain its leadership in the total network storage market (Nas combined with Open San), with 26.3 per cent revenue share.
In the Open San market, HP was number one with a 27.9 per cent share, followed by EMC with 24.5 per cent. In the Nas market, Network Appliance maintained its number one position with 37.3 per cent share, followed by EMC with 33.7 per cent.
