Sony is pulling the plug on nearly its entire memory card operation. Not because the products failed. Not because demand vanished. Because there aren’t enough NAND flash chips to go around.
The company announced in late March that it would discontinue sales of SD cards, microSD cards, and CFexpress Type A memory cards, effective once current inventory runs dry. The only survivor: Sony’s CFexpress Type B cards, which cater to high-end professional photographers and videographers. Everything else — the cards that go into cameras, drones, dashcams, handheld gaming devices, and countless other consumer electronics — is being wound down, as first reported by Slashdot.
The timing is striking. Sony didn’t just sell memory cards — it helped define the category. The company co-developed the original Memory Stick format in 1998, a proprietary standard that powered PlayStation Portables, Cyber-shot cameras, and VAIO laptops for years. Its SD and microSD products became staples among professional photographers who trusted the brand’s reliability. Now, a supply chain crisis driven by insatiable demand for solid-state drives is squeezing out the very products that once anchored Sony’s storage business.
The root cause is a global NAND flash shortage that has been building for months. NAND flash memory — the underlying technology in both SSDs and memory cards — is produced by a handful of manufacturers: Samsung, SK Hynix, Kioxia, Western Digital, and Micron. These companies have been aggressively shifting production capacity toward SSDs, which command higher margins and serve the exploding markets of data centers, artificial intelligence infrastructure, and consumer computing. Memory cards, by comparison, are a low-margin, mature product line. When allocation decisions get made at the fab level, cards lose.
Sony’s announcement is the clearest signal yet that this reallocation is having real casualties. The company’s official statement cited the SSD shortage directly, an unusual level of candor for a company that typically frames product discontinuations in terms of strategic portfolio optimization. There was no spin here. Sony essentially said: we can’t get the chips.
This matters beyond Sony. The memory card market, while not as glamorous as the SSD business, remains a multi-billion-dollar global industry. Research from TrendForce and other semiconductor analysts has shown that NAND flash contract prices have risen sharply in recent quarters, with some categories seeing double-digit percentage increases. The squeeze is particularly acute for cards because they use the same 3D NAND dies that go into enterprise and consumer SSDs — but the volumes are smaller, the margins thinner, and the bargaining power weaker.
For professional photographers and videographers, the implications are immediate. Sony’s CFexpress Type A cards were a favorite among users of the company’s own Alpha-series mirrorless cameras, which feature dual card slots accepting both CFexpress Type A and SD formats. Losing the Type A cards means those shooters will need to source alternatives from competitors like ProGrade Digital or Exascend — companies that may face their own supply constraints. The retention of CFexpress Type B cards suggests Sony is protecting its highest-margin, highest-performance product, likely because the professional broadcast and cinema market it serves can absorb higher prices and justify priority allocation.
And then there’s the consumer side. SD and microSD cards remain ubiquitous in everyday electronics. Nintendo’s Switch consoles use microSD for expanded storage. Action cameras from GoPro and DJI rely on them. Security cameras, car dashcams, single-board computers like Raspberry Pi — all of these depend on a steady supply of affordable flash memory cards. Sony’s exit from this market doesn’t mean these products disappear, but it does mean one fewer major supplier competing on quality and price. SanDisk (owned by Western Digital), Samsung, and Kingston will absorb some of that market share. Whether they can do so without raising prices in a supply-constrained environment is another question entirely.
The broader NAND shortage traces back to several converging forces. AI training and inference workloads have driven unprecedented demand for high-capacity, high-speed storage in data centers. The rollout of PCIe Gen 5 SSDs in consumer PCs has increased per-unit NAND consumption. Smartphone manufacturers continue to push storage capacities higher — 512GB and 1TB options are now common in flagship devices. Meanwhile, NAND manufacturers have been cautious about adding new capacity after a brutal downturn in 2023 that saw flash prices crater and several producers cut production to stabilize the market. The recovery has been faster and steeper than most anticipated, and the industry now finds itself short.
SK Hynix and Samsung have both signaled plans to expand 3D NAND production, but new fab capacity takes 18 to 24 months to come online. Kioxia, which went public in late 2024 after years of ownership uncertainty, is investing in its Yokkaichi and Kitakami facilities in Japan but faces its own capital constraints. The result is a supply gap that won’t close quickly — and that will continue to pressure lower-priority product categories like memory cards.
Sony’s decision also reflects a cold strategic calculus. The company’s semiconductor division is overwhelmingly focused on image sensors, where it holds dominant global market share. Storage products were always a secondary business line. Exiting memory cards frees up procurement bandwidth and capital that can be redirected toward sensors, which are critical to Sony’s camera, smartphone, and automotive businesses. It’s a rational move. But it’s also an acknowledgment that Sony can’t compete for NAND allocation against the companies that actually manufacture the chips.
There’s an irony here that industry veterans will appreciate. Sony was once a vertically integrated electronics giant that manufactured its own semiconductors, its own displays, its own storage media. The company made floppy disks, optical discs, MiniDiscs, Memory Sticks, and Blu-ray media. One by one, those businesses have been shed or wound down as the economics shifted. Memory cards were among the last holdouts. Their departure marks another step in Sony’s long transformation from a hardware conglomerate into a company focused on content, sensors, and services.
So what happens next? In the near term, expect memory card prices to rise across the board, not just for Sony-branded products. Distributors and retailers who still have Sony inventory will likely see it move quickly once word spreads. The secondary market for high-end Sony cards — particularly the tough series and SF-G series — could see a premium. For working professionals, the message is clear: stock up now or switch brands.
Longer term, the memory card format itself faces an existential question. As devices increasingly move toward internal storage, wireless transfer, and cloud-based workflows, the addressable market for removable flash cards is shrinking. Cameras are one of the last major consumer electronics categories where swappable storage remains standard. If the NAND shortage accelerates the trend toward larger internal buffers and direct-to-cloud capture, memory cards could follow optical discs into niche obsolescence within a decade.
That’s not a certainty. But Sony’s exit is a data point that’s hard to ignore.
The company has not announced an exact end-of-sale date, saying only that products will remain available while supplies last. Given current demand conditions, that window may be shorter than anyone expects.
