One hundred twenty-two terabytes is enough to hold thousands of high-definition movies, or the working data of a mid-size company for years. Huawei says it can now build a drive that large without importing the advanced memory chips that U.S. rules were designed to keep out of its hands.
The Chinese technology giant has developed a 122-terabyte solid-state drive using its own packaging technology, a workaround for the export controls that have cut off its access to high-end 3D NAND memory, according to Readhub. Instead of relying on imported high-density NAND, the drive stacks and packages memory dies that Huawei can source, an approach the company hopes closes the capacity gap with Western and Korean rivals in enterprise storage.
The packaging workaround
The approach hinges on advanced packaging: combining multiple smaller memory dies into a single high-capacity module rather than depending on a single, cutting-edge die. That matters because U.S. export controls restrict the transfer of advanced 3D NAND technology to Chinese firms, including equipment, designs and, in some cases, the chips themselves. Memory makers seeking to sell high-layer-count NAND to Huawei must navigate licensing requirements, and at least one major supplier, Micron, has been barred from selling to the company outright.
Packaging is the legal and technical path around the wall. By assembling the drive from dies it can obtain, Huawei sidesteps the layer-count restrictions at the center of the rules. The trade-offs are real: stacked designs add complexity, cost and thermal load, and drives built this way may trail single-die products on performance and endurance. The capacity number, however, is the point. A 122-terabyte drive puts Huawei at the top of the enterprise storage market by size alone.
The sanctions context
The drive is part of a broader campaign for semiconductor self-reliance. Washington’s restrictions on advanced NAND have targeted precisely the technology that makes high-capacity drives possible: the 3D stacking that lets manufacturers pack hundreds of layers of memory cells into a single chip. Chinese companies have responded by building out domestic alternatives, led by Yangtze Memory Technologies, and by engineering around the restrictions where alternatives do not yet exist.
For Huawei, storage is a business as much as a symbol. The company sells enterprise storage systems, servers and cloud infrastructure across China and much of the developing world, and its data-center customers need the same densities that Western hyperscalers buy from Samsung, SK Hynix and Kioxia. A domestically assembled 122-terabyte drive gives Huawei a product it can offer at scale without depending on suppliers that U.S. policy can switch off.
The packaging path also fits Huawei’s playbook. The company has used similar techniques elsewhere, combining available components and its own chip designs to keep products competitive under sanctions. The SSD is the latest proof that export controls can slow a company without stopping it, and that the cost of the workaround shows up in complexity and margin rather than in absence from the market. It is a calculation other sanctioned companies are watching closely, because if packaging can substitute for advanced NAND in storage, the same logic may reach other chips.
The capacity race
Huawei’s 122-terabyte drive enters a market that is moving in the same direction. Solidigm shipped a 122-terabyte drive using QLC NAND in 2023, and Samsung has shown 128-terabyte-class products for the data-center segment. The demand driver is artificial intelligence: training clusters and inference farms generate data at a pace that makes raw capacity a selling point, and hyperscalers pay a premium for density that shrinks the number of drives and racks they must manage.
The question is how much of that market Huawei can reach. Export controls limit where it can sell certain products, and Western cloud providers are unlikely to buy Chinese enterprise storage for their core fleets. But the domestic Chinese market is large, and Huawei’s reach into government, telecom and enterprise data centers gives the drive a substantial addressable audience that does not depend on Western approval.
Analysts who track Chinese semiconductors see the drive as a milestone with caveats: it demonstrates engineering and manufacturing capability, but it does not resolve the underlying gap in advanced memory production, where Chinese fabs still trail the leaders by a wide margin. The 122-terabyte drive is a workaround, not a breakthrough in the fundamental technology the sanctions target.
Bottom line
Huawei’s 122-terabyte SSD is a symbol of what Chinese technology companies have learned to do under sanctions: engineer around the wall. The packaging workaround keeps Huawei in the high-capacity storage market without the imported 3D NAND the rules were meant to deny it, and it gives Chinese data centers a homegrown option at the top of the capacity ladder. What it does not do is close the technology gap at its root, which is why the drive matters as much for what it represents as for what it stores.
