Total disk storage sales, which include storage subsystems found within servers, rose 1.3% in Q4 after dropping 5.6% in Q3. IDC attributes the turnaround to "traditional year-end budget flushes, improved economic sentiment, and a strong desire to address long-standing storage infrastructure inefficiencies."
Market leader EMC, which posted strong Q4 numbers to go with light guidance, saw its external disk share rise 220 bps Y/Y to 32.9%, and its total disk share rise 200 bps to 25.8%. The gains largely came at the expense of restructuring IBM, whose shares respectively fell 190 bps and 200 bps to 13% and 14%.
H-P's (HPQ) external disk share rose 30 bps to 9.6%, and its total disk share 40 bps to 16.3%. NetApp (NTAP), which delivered nearly in-line revenue and soft guidance last month, saw its external share fall 10 bps to 11.5%, and its total share stay flat at 9%. Private Dell's total share fell 140 bps to 9.9%.
