Total worldwide enterprise storage systems factory revenue grew 7% year over year to nearly $10.6 billion during the fourth quarter of 2014, according to the International Data Corp. (IDC) Worldwide Quarterly Disk Storage Systems Tracker.

Total capacity shipments were up 44% year over year to 31.8 exabytes during the quarter. Spending for the full year was up 7% to $36.2 billion. Full-year capacity consumption was up 43% to 99.2 exabytes.

"The storage market had a strong finish to 2014," Eric Sheppard, research director for storage at IDC, said in a statement. "Fourth quarter spending on enterprise storage systems was up strongly in most major geographic markets, driven by traditional year-end seasonality, demand for midrange systems that incorporate flash capacity, and continued growth of systems designed for hyperscale datacenters."

EMC was the largest external storage systems supplier during the quarter, according to the report. The company accounted for 33% of sales, which was the same share as the previous year. IBM and NetApp generated 12% and 11% of total sales during the quarter, respectively. HP generated 10% of the revenue during the quarter.
