External disk storage systems market hit 46.6bn in Q4
The external disk storage systems market was in part driven by emerging markets in Q4.

The global external disk storage systems market grew 7.7% year-on-year in Q4 2011, with factory revenues reaching $6.6 billion, according to IDC.

The total disk storage systems market grew to just over $8.5 billion in revenues, up 3.5% growth year-on-year, while total disk storage systems capacity shipped reach 6,279 petabytes, a 22.4% jump.

"The external disk storage systems market ended 2011 with strong year-over-year revenue growth that helped to push the market to 10.6% growth for the entire year," said Liz Conner, senior research analyst, Storage Systems IDC.

"Helping to drive the overall market growth were the emerging regions, which posted high, sustained growth in 2011. In contrast, the mature regions saw growth soften as their economies entered the recession recovery phase. Another factor underlying the 2011 growth, and specifically the fourth quarter gain, was the delayed impact of the drive shortage caused by the Thailand floods. The enterprise storage market is expected to start feeling the brunt of this shortage in 2012, resulting in minimal impact on the fourth quarter and 2011 as a whole."

EMC maintained its lead in the external disk storage systems market with 29.4% revenue share in the fourth quarter, up 22.4% year-on-year. IBM was second with 15.2% market share. NetApp and HP tied for third with 11.2% and 10.3% market shares, respectively. Hitachi ended the quarter in fifth position, with 9.2% share.

The total open networked disk storage market (NAS Combined with Open / iSCSI SAN) grew 9.6% year over year in the fourth quarter to $5.6 billion in revenues, while the Open SAN market, grew 14.1% year over year. The NAS market declined 1.2% year over year.

"The high-end segment (average selling price $250,000 and over) followed a seasonal trend in the fourth quarter with highest sequential growth across all storage segments," said Amita Potnis, senior research analyst, Storage Systems. "The share of high-end storage systems increased from 28.2% in 2010 to 30.0% in 2011. This increase was most notable outside the United States. Drivers for this increase include economic recovery, storage consolidation, and datacenter build-up and upgrades."
