FRAMINGHAM 4 MARCH 2011 - Last year, hard disk drive manufacturers shipped 5,127 petabytes of storage capacity, a 55.7% increase over 2009, according to a report released Friday by market research firm IDC. A petabyte equals 1 million gigabytes, and 1 exabyte equals 1,000 petabytes.
In the fourth quarter of 2010 alone, worldwide external disk storage systems revenues saw year-over-year growth of 16.2%, or just under $6.1 billion, according to IDC's Worldwide Quarterly Disk Storage Systems Tracker.
In the fourth quarter of 2010, the total disk storage systems market grew about $8.3 billion in revenue, representing 14.3% growth year over year.
"The fourth quarter of 2010 continued the trend of economic recovery and helped close a successful year for disk storage," said Liz Conner, IDC's senior research analyst for storage systems.
Conner attributed the increase in disk drive sales to a loosening of IT budget purse strings by corporate executives, which allowed for 25.7% year-over-year growth in network storage systems.
Revenues for all the major storage vendors were up across the board.
Factory revenues for the total disk storage systems market grew by 18% to $28.7 billion in 2010 compared with 2009. Hewlett-Packard and EMC maintained their top spots as revenue leaders at 19% of the market each, followed by IBM and Dell, with 16% and 11.9% shares, respectively.
In 2010, HP and EMC raked in $5.4 billion in sales each. IBM and Dell took in $4.5 billion and $3.4 billion in revenue, followed by Dell and NetApp with $3.4 billion and $2.3 billion, respectively.
In the fourth quarter of 2010, EMC garnered a 26% external storage systems revenue share, followed by IBM and HP, at 16.3% and 11.6%, respectively. NetApp ended the quarter in fourth position, with 10.3% of the market share. Hitachi Data Systems and Dell were statistically tied at 8.7% and 7.9%, respectively, IDC stated in its report.
Network storage systems based on Ethernet, rather than on the Fibre Channel protocol, saw a significant jump in the fourth quarter, with network-attached storage and iSCSI systems sales growing 21.7% year over year, with $5.1 billion in revenues.
EMC also maintained its lead in the latter category, with a 29.7% revenue share, followed by IBM at 15.2%.
Separately, the NAS market grew 41.3% year over year. EMC also led that category, with a 52.8% revenue share, followed by NetApp at 23.7%. The iSCSI SAN market continues to show strong momentum, posting 42.1% revenue growth compared with the prior year's fourth quarter. Dell led the market, with a 32.6% revenue share, followed by HP in second and EMC in third, with 14.7% and 13.4%, respectively.
