Seagate in Q3 2006 shipped 39.1 mln HDDs, up from 33.6 mln in Q2 2006. The company’s unit market share rose slightly to 34.3%, up from 34.1% in Q2 2006. The company retained its lead in the largest segment of the HDD market: desktop PCs, an area that encompasses not only traditional desktop computers, but also entry-level servers and enterprise backup systems. Consisting mostly of 3.5-inch drives, the desktop segment’s high volumes represent the bread and butter business of major HDD suppliers like Seagate. Seagate also continued to dominate the key enterprise HDD segment with a 58.4% share of unit shipments. The next closest competitor in this segment, Fujitsu Ltd., took a 25.9% share of unit shipments, iSuppli says.
