UNITED STATES The external disk storage systems market grew 8.6 percent year over year to $US 3.8 billion in the second quarter of 2005, according to IDC.
The overall storage systems market, which includes both standalone and internal systems grew at a rate of 9.9 percent to US $5.6 billion in the second quarter of 2005, marking the highest year-over-year growth in the last eight quarters. Capacity continues to outpace overall revenue growth with total disk storage systems petabytes growing 59.3 percent year over year to 457 petabytes for the second quarter.
"The high growth for external systems represents continued investment in networked storage, while the growth in internal storage indicates richer configurations and increased sales of servers with three or more hard disk drives," said Brad Nisbet, program manager in IDC's Storage Systems program.
EMC maintained its lead in the external disk storage systems market with 21.2 percent revenue share, followed by HP and IBM with 18.8 percent and 13.8 percent revenue share, respectively.
Dell edged out Hitachi for the fourth position with 8.3 percent revenue share while Hitachi ended the quarter with 7.3 percent. Three of the top five vendors had double-digit growth during the second quarter with Dell leading the way with 27.1 percent year-over-year growth followed by HP and IBM, each with more than 13 percent year-over-year growth.
"The top five vendors accounted for almost 70 percent of the external disk storage systems market – up from 68 percent a year ago, confirming the maturity of the market," said Natalya Yezhkova, senior research analyst, IDC Storage Systems. "Four of the top five vendors gained market share benefiting from the success of their midrange products."
Network disk storage systems
The total network storage market (NAS combined with Open and iSCSI SAN) posted 16.1 percent year-over-year growth in the second quarter to nearly US $2.5 billion.
EMC continues to maintain its leadership in the total network storage market with 27.9 percent revenue share, followed by HP with 21.3 percent. Dell and IBM posted the strongest YOY revenue growth for the quarter among the top five vendors, with 33.2 percent and 22.9 percent growth, respectively.
The Open/iSCSI SAN market grew 17.8 percent YOY, surpassing US $2 billion in revenues for the first time. EMC had 25 percent revenue share and HP had 24.8 percent revenue share for the second quarter. Dell and IBM posted the strongest revenue share gain among the top five vendors, with 1.6 and 0.6 share point gain, respectively.
In the NAS market, which grew 9.5 percent year over year, EMC led with 40.2 percent revenue share, followed by Network Appliance with 35.2 percent share.
