IDC: Worldwide External Disk Storage Systems Experience Year-over-Year 19-Percent Growth in Third Quarter

Worldwide external disk storage systems factory revenues posted year-over-year growth of 19.0 percent, totaling slightly less than US$5.2 billion, in the third quarter of 2010, according to the International Data Corporation (IDC) Worldwide Quarterly Disk Storage Systems Tracker. For the quarter, the total disk storage systems market grew to nearly $7.0 billion in revenues, representing 18.5-percent growth from the third quarter of 2009. Total disk storage systems capacity shipped reach 4,299 petabytes, growing 65.2 percent year over year.

"Users are making up for their reduced storage spending in 2009 as the third quarter recorded the fourth highest revenues in a single quarter for external disk storage systems," said Liz Conner, Senior Research Analyst, Storage Systems. "The increased investment by end users and vendors alike in iSCSI SAN and NAS (41.4- and 49.8-percent year-over-year growth respectively) has helped fuel the overall growth, while easing budget constraints sparked a pickup in FC SAN and higher-end systems alike."

EMC maintained its lead in the external disk storage systems market with 26.1-percent revenue share in the third quarter, followed by IBM in second with 12.9-percent market share. NetApp and HP are in a statistical tie for third place with 11.6- and 11.1-percent market share respectively. Dell ended in the fifth position with 9.1-percent market share. Given the recent acquisitions of 3PAR and Isilon, IDC notes that for third quarter of 2010, 3PAR's and Isilon's share in the total external disk storage systems market was 0.83 and 0.75 percent respectively.
The total open networked disk storage market (NAS combined with Open/ iSCSI SAN) grew 26.4 percent year over year in the second quarter to $4.3 billion in revenues. EMC continues to maintain its leadership in the total open networked storage market with 30.0-percent revenue share, followed by NetApp with a 14.0-percent revenue share.

In the Open SAN market, which grew 18.5 percent year over year, EMC was the leading vendor with 23.0-percent revenue share, followed by IBM in second and HP in third with 15.5- and 14.3-percent share, respectively.

The NAS market grew 49.8 percent year over year, led by EMC with 46.6-percent revenue share and followed by NetApp with 28.9-percent share. The iSCSI SAN market continues to show strong momentum, posting 41.4-percent revenue growth compared to the prior year's quarter. Dell led the market with 33.8-percent revenue share, followed by EMC and HP, in a statistical tie for second, with 13.8- and 13.7-percent market share respectively.

"The economic crisis of 2009 and commensurate budget reductions compelled end users invest in lower-priced storage systems that still offer enterprise-level features," said Amita Potnis, Senior Research Snalyst, Storage Systems. "Although most IT budget restraints have been lifted, the trend toward lower-priced systems continued into 2010 as revenues for external storage systems in the lower-price bands increased by 21.1 percent year over year. End-users keep looking to get the most for their money, while vendors continue to invest resources to develop storage systems that meet this need."
