Morgan Stanley says data center HDD and SSD demand stays strong, with enterprise SSD capacity seen doubling by 2026
Morgan Stanley said in a report released on Aug. 3 that June HDD and SSD data continued to point to strong demand from data centers. Citing TSR estimates, the bank said enterprise SSD shipment capacity for data center use is projected to reach 525 exabytes in 2026, up 100% year over year, while nearline HDD shipment capacity is expected to reach 1,845 exabytes, up 30.4%. The report said June data center enterprise SSD shipment capacity came in at 46.33 exabytes, rising 124.5% from a year earlier and 12.0% from the prior month. Unit shipments of enterprise SSDs reached 6.35 million, up 41.1% year over year and 8.9% month over month. Morgan Stanley said the mix shift toward higher-capacity products should keep shipment-capacity growth ahead of unit growth. On the HDD side, June nearline HDD production totaled 7.03 million units, up 12.3% year over year and down 0.6% from the previous month. TSR expects nearline HDD production to reach 84.39 million units in 2026, up 12.8%. The report also warned that further nearline HDD output increases could be constrained by head supply and testing capacity. Overall, Morgan Stanley said AI spending and data center capital expenditure are still driving storage-capacity demand, while supply-chain bottlenecks are spreading from end devices to key component links.
