Hewlett-Packard held on to its lead in the disc storage systems market in the second quarter, but saw a decline in revenue and market share, according to market researcher IDC.
HP led the rankings for total worldwide disc storage systems factory revenue in the second quarter, but saw its revenue in this market decline 8.9% to $1.15bn (£65m), from $1.26bn in the same quarter a year ago, and its market share slip to 23% from 26.5% a year earlier.
IDC estimated that the market for disc storage systems grew by 5% overall, to $5bn, from $4.77bn a year earlier. It defines the systems as an assembly of controllers, cables and host bus adapters associated with three or more disks, located either within a server or outside it.
IBM held on to second place, with disc storage system revenue growing 6.2% year on year to $1.02bn, compared with $957m a year earlier, and market share inching up to 20.3% from 20.1% a year earlier.
EMC made the biggest year-on-year gain in market share, moving from 12.6% to 14.4%, according to IDC, but remained in third place with its disc storage system revenue for the quarter up 19.5% to $719m from $602m a year earlier.
Sun Microsystems' revenue and market share declined, but with disc storage system revenue of $379m it remained just ahead of Dell, which notched up the biggest year-on-year revenue growth rate in the survey, 21.7%, taking its disc storage system revenue to $365m from the previous year's figure of $300m.
EMC topped the external disc storage systems market share with 20.7% and revenue of $719m. HP came second, although its market share slipped to 18.2% from 21.4% a year earlier, and its revenue from this sector slipped 8.3% to $631m.
IBM stayed in third place with revenue of $471m, up 4.7% year on year. Sun and Hitachi Data Systems almost tied for fourth place in this sector, with revenue of $282m, down 2%, and $281m, up 4.7%, respectively.
Other suppliers accounted for the remaining 31.4% of this market, which IDC estimated is worth $3.48bn, up 8% on the previous year's quarter.
