GoKawiilIn a world of rapidly developing artificial intelligence, the supply of computer hardware can barely meet demand, and at this point, long-term supply agreements (LTAs) become compulsory. When it comes to storage — both hard disk drives and solid-state drives — LTAs now span from three to five years, depending on the device. While some may argue that now all the supply will get to large customers, such agreements with guaranteed offtake may actually be good for consumers.
Up to five year LTAs
When it comes to SSDs, long-term supply agreements now span five years, according to Sandisk.
"The duration of this agreement varies, with the longest contract extending to five years," said Luis Visoso, chief financial officer of SanDisk, in an earnings call with analysts and investors. "In aggregate, volume commitments increased during the life of the contracts with quarterly commitments and a combination of fixed and variable pricing. […] These agreements are tailored to meet the needs of our customers and, in aggregate, provide us with demand certainty at financials that we expect will be consistent with our fiscal fourth quarter guidance."
Something similar applies to hard drives, though LTA visibility of Seagate and Western Digital is a bit shorter. In the case of Seagate, the company is even talking about bespoke storage systems.
"We have exabyte-scale supply agreements in place with nearly all major cloud and hyperscale customers, with nearline capacity almost fully allocated through calendar 2027," said William Mosley, chief executive of Seagate, in the company's most recent conference call. "At the same time, we are finalizing build-to-order contracts with these customers through the end of fiscal 2027, which defines specific configuration and pricing. Our value-based pricing approach enables customers to plan with confidence while contributing to sustained profit growth for Seagate, and we are actively engaged in strategic planning discussions now reaching into calendar 2028 and beyond."
The same applies to Western Digital. "Our long-term visibility continues to improve, with the duration of our agreements now extending into calendar year 2028 and calendar year 2029," said Irving Tan, chief executive of Western Digital.
Clear visibility
For years, storage has been considered a commodity, so now these long-term supply agreements give storage makers unusually clear visibility into real demand, which enables them to scale production in a far more disciplined way. SanDisk, Seagate, and Western Digital can now align NAND wafer starts, HDDs, HDD media output, and controller supply with multi-year volume commitments instead of reacting to short-term market demand. On the one hand, this reduces the risk of overbuilding capacity; on the other hand, it may ensure a lack of underinvesting ahead of demand increases.
