Disk storage sales surged in '05, says IDC

IDG News Service - An explosion of data and the availability of storage systems that can help businesses tackle data protection and business continuity issues drove a record year of growth for the disk storage systems in 2005, according to IDC.

IDC's 2005 Worldwide External Disk report stated that storage system sales worldwide jumped nearly 18% to $4.7 billion in the fourth quarter of 2005 from the \year-ago quarter, and for the year grew 12% to $16 billion from the prior year.

"We've seen kind of blas¿ growth since the bottom fell out in 2001; it's nice to see that throughout 2005 we were accelerating," said Brad Nisbet, program manager, IDC Storage Systems, in Framingham, Mass.

Sales of midrange systems, which IDC defines as priced between $50,000 and $149,999, were especially strong, said Nisbet.

"The sweet spot continues to be midrange products," he said. "A lot of the features and functionality once only in the high end has migrated its way down to lower segments of market. That, combined with the fact that many midrange products offer multiple tiers of storage, is driving the growth."

Multiple-tiered storage is helping users to address such challenges as data protection and business continuity, Nisbet said.

EMC Corp. held the lead in the external storage systems market in the fourth quarter, taking about 21% of the market. Behind EMC was Hewlett-Packard Co., with 18%, and IBM, with 16%, which both showed marked improvement from the prior year, Nisbet said.

"For some time, we had seen companies like EMC and Dell and NetApp that were the ones that stood out, while everyone else was lackluster and flattish year over year," Nisbet said. "It's nice to see HP and IBM in particular with good growth. IBM really turned themselves around and are executing well now, and the same can be said for HP."

The network disk storage market, which includes NAS (network-attached storage) and Open and iSCSI SANs (storage-area networks), grew 24% to about $3 billion in the fourth quarter from the prior year-ago quarter. EMC led in that market, with about 27% share, followed by HP, with 20%, and IBM, with 14%.

Turning to the NAS market, revenue grew 23% in the quarter from the same year-ago period. EMC led that market as well with 40% share, followed by NetApp with 32% share.

The iSCSI SAN market soared 130% from the prior year's quarter to $94 million. NetApp led the market, with 26% share, followed by EMC with 21% share.

All told, the overall disk storage systems market grew about 11% to $23.7 billion in 2005. HP led the overall market with 23% share, followed by IBM with 20%, and EMC with 14%.
