Seagate makes the hard drives and storage systems that hold the world's data.
Seagate builds the spinning hard drives that store a huge share of the world's digital information. Every photo you back up, every email your company archives, every video sitting on a cloud server has a good chance of living on a Seagate drive somewhere. The company sells these drives to big cloud providers, to businesses building data centers, and to people buying a drive for a personal computer or a gaming console.
The business runs on a simple fact: all that data has to sit somewhere, and hard drives are the cheapest way to store enormous amounts of it. A hard drive is a stack of magnetic disks spinning at high speed while a tiny read-and-write head floats just above the surface, saving and fetching data in microseconds. Seagate buys the parts, assembles the drives, and sells them — mostly to a small handful of giant customers. That means the company lives and dies by how many drives the big cloud builders order and at what price. For years this was a mature, cyclical business with little excitement, but artificial intelligence changed the mood. AI systems need to train on and store staggering volumes of data, and the cloud companies have been ordering more storage to keep up. Seagate's newest large drives, packed with more disks using a clever trick called heat-assisted recording that lets each disk hold far more data, are selling well. Management has said demand has been running ahead of what it can supply, which is the kind of problem a drive maker likes to have.
The company has also faced real trouble. In 2023 it agreed to pay a $300 million penalty to settle US charges that it shipped drives to a major Chinese customer, Huawei, after export rules restricted those sales — a reminder that this is a hardware business caught up in geopolitics. Seagate leans on its free cash flow to pay a dividend and buy back shares; one earlier buyback program retired a meaningful chunk of the shares outstanding. The core bet is straightforward: the world keeps generating more data, and somebody has to sell the cheap spinning disks that hold it.
