Sony is getting out of the memory card business. Not gradually. Not quietly winding things down over a few product cycles. The company announced it will halt sales of recording media — SD cards, microSD cards, and CFexpress cards — by March 2026. For a brand synonymous with portable storage since the Memory Stick era, the decision is striking. But the reasoning behind it tells a far more consequential story about where the global semiconductor industry is headed and who’s winning the war for finite chip-fabrication capacity.
The announcement, first reported by Digital Trends, confirms that Sony will discontinue its Tough series SD and microSD cards as well as its CFexpress Type A and Type B cards. These aren’t commodity products. Sony’s Tough-series cards are built for professional photographers and videographers — weather-sealed, drop-resistant, and engineered for sustained high-speed write performance. They command premium prices. And yet, Sony has decided the NAND flash memory required to manufacture them is more valuable elsewhere.
Elsewhere, in this case, means artificial intelligence.
The Economics of Choosing AI Over Storage Cards
Sony didn’t frame the decision as a retreat. In its official statement, the company pointed to what it described as increasing demand for memory and storage in AI and data center applications. The calculus is straightforward: the same NAND flash wafers that go into a 256GB CFexpress card can be redirected toward enterprise SSDs powering AI training clusters, where margins are fatter and volume demand is exploding. When the world’s largest technology companies are spending tens of billions of dollars annually on AI infrastructure, a memory card product line — even a well-regarded one — simply can’t compete for internal resources.
This isn’t a Sony-specific phenomenon. It’s an industry-wide reallocation. NAND flash manufacturers including Samsung, SK Hynix, and Kioxia have all signaled shifts toward high-capacity enterprise storage. The AI training and inference workloads running on NVIDIA’s H100 and B200 GPUs require enormous amounts of fast storage. A single large language model training run can consume petabytes of data throughput. The storage subsystems feeding these operations need enterprise-grade SSDs — lots of them — and the flash memory to build those drives has to come from somewhere.
So it’s coming from consumer products. Memory cards are among the first casualties.
Sony’s flash memory operations are intertwined with its broader semiconductor business, which also produces the CMOS image sensors found in roughly 70% of the world’s smartphones. The company has been investing heavily in expanding its semiconductor fabrication capacity, but those investments are targeted at image sensors and AI-adjacent applications, not consumer storage media. Capital expenditure follows margin. And right now, AI infrastructure offers margins that memory cards never could.
The photography community reacted with a mix of frustration and resignation. Sony’s Tough cards had earned a loyal following among professionals shooting with Sony Alpha mirrorless cameras, particularly the A1 and A9 III, which use CFexpress Type A slots. ProGrade Digital, Lexar, and other manufacturers still produce compatible cards, but Sony’s exit removes a trusted first-party option. For working photographers, the concern is less about availability today and more about what the trend signals for the future of niche storage formats.
A Broader Pattern of Consumer Sacrifice
Sony’s move is part of a pattern that has been accelerating throughout 2024 and into 2025. AI’s demand on semiconductor supply chains is reshaping product priorities across the industry. TSMC, the world’s dominant contract chipmaker, has reportedly deprioritized certain legacy node production runs to free capacity for advanced AI chip orders from Apple, NVIDIA, AMD, and Broadcom. Automotive chipmakers have complained about allocation squeezes. Now, memory products are feeling the same gravitational pull.
The numbers tell the story. Global spending on AI servers is projected to exceed $150 billion in 2025, according to industry estimates. Each AI server requires significantly more DRAM and NAND flash than a conventional enterprise server. SK Hynix, which produces the High Bandwidth Memory (HBM) chips essential to AI accelerators, has seen its stock price more than double over the past 18 months on the strength of AI-driven demand. Samsung’s semiconductor division, after a bruising downturn in 2023, has rebounded almost entirely on the back of AI memory orders.
In this environment, a memory card product line generating perhaps tens of millions of dollars in annual revenue is a rounding error. The opportunity cost of allocating NAND flash to consumer cards instead of enterprise SSDs is simply too high. Sony appears to have done the math and made the rational choice.
But rational for Sony doesn’t necessarily mean painless for its customers. The company’s imaging division — which sells the cameras these cards go into — now depends entirely on third-party storage manufacturers. That’s a subtle but meaningful erosion of the integrated product experience Sony has long cultivated. When a photographer buys a $6,500 Sony A1 body, the ability to also buy a Sony-branded card engineered specifically for that camera’s write speeds was part of the value proposition. That link is being severed.
The discontinuation also raises questions about the CFexpress Type A format itself. Sony and Nikon are the primary camera manufacturers using CFexpress Type A, which offers a smaller physical footprint than Type B but with lower maximum throughput. With Sony no longer manufacturing Type A cards, the format’s long-term viability depends on third-party commitment. ProGrade and Lexar have shown no signs of abandoning it, but format support tends to follow manufacturer investment. If Sony’s card exit is a leading indicator of reduced enthusiasm for Type A, photographers locked into that format could eventually face a narrowing selection of compatible media.
None of this is happening in isolation. The broader consumer electronics industry is adjusting to a world where AI workloads command first priority on component supply chains. Smartphone makers have faced DRAM allocation challenges. Gaming console manufacturers have navigated SSD supply constraints. Even the automotive sector — which fought bitterly for chip access during the 2021-2022 shortage — is watching AI absorb fabrication capacity that might otherwise serve its needs.
What makes the Sony memory card story notable isn’t its scale. It’s its clarity. A major electronics manufacturer looked at a profitable, well-reviewed product line and decided that the raw materials going into it were worth more feeding AI infrastructure. That’s not a strategic pivot born of product failure. It’s pure resource economics.
What Comes Next
For professional photographers and videographers, the immediate impact is manageable. Third-party card options remain plentiful, and Sony’s existing inventory will continue circulating through retail channels for some time. The Tough series won’t vanish overnight.
The longer-term implications are harder to predict. If AI demand continues growing at its current trajectory — and every major forecast suggests it will — more consumer-oriented semiconductor products could face similar discontinuations. Niche storage formats, specialty memory modules, and low-volume chip products are all vulnerable when fabrication capacity is constrained and AI buyers are willing to pay premium prices for every available wafer.
Sony has said it will continue honoring warranties on existing memory card products and will maintain support infrastructure through the transition period. The company’s imaging division, meanwhile, continues to invest in new camera bodies and lenses, suggesting no broader retreat from the photography market. The message is nuanced: Sony still wants to sell you a camera. It just doesn’t want to sell you the card that goes inside it anymore.
And that distinction — between the products companies choose to keep making and the ones they quietly abandon — may be the most telling indicator of where the semiconductor industry’s center of gravity now sits. It sits with AI. Everything else is negotiable.
