AI’s Hunger for NAND is Killing the High-End Portable SSD

The high cost of speed
For nearly two decades, LaCie’s bright orange rugged drives have been a staple in the bags of freelance videographers and field journalists. But a new disruption in the global supply chain is forcing the brand to prune its catalog in a way that defies traditional product lifecycles. Global Distribution has confirmed that two of the newest and fastest models in the lineup—the Rugged SSD4 and the Rugged SSD Pro5—are being discontinued.
Usually, a product is axed because it has become obsolete or sales have plummeted. In this case, it’s the opposite. Both drives were launched only last year and represented the bleeding edge of portable storage. The SSD4 utilized a 40 Gbps USB4 interface to hit read speeds of 4,000MB/s, while the Pro5 leveraged the nascent Thunderbolt 5 standard to reach a staggering 6,700MB/s read and 5,300MB/s write rates. To see products with these specifications vanish from the roadmap after less than 18 months is an anomaly that points to a deeper systemic issue in the hardware market.
The AI vacuum
The culprit is a severe shortage of high-performance NAND flash memory. While consumers have noticed creeping price hikes in standard SD cards and consumer SSDs throughout the year, the impact is most visceral at the high end of the performance spectrum. The specific, high-bin NAND required to sustain the speeds of a Thunderbolt 5 drive is becoming increasingly difficult—and expensive—to procure.
This isn’t a random supply glitch; it is the direct result of the AI gold rush. Data centers powering Large Language Models (LLMs) and generative AI require astronomical amounts of high-bandwidth memory and ultra-fast SSD storage to handle training sets and real-time inference. Tech giants like Nvidia, Meta, and Google are effectively vacuuming up the world’s supply of premium silicon, leaving consumer-grade manufacturers like Seagate (LaCie’s parent company) to fight for the scraps.
When AI clusters pay a premium for every available wafer of high-performance NAND, the economics of a portable drive break. It is likely that the components for the Rugged SSD Pro5 still exist, but the cost to acquire them has surged to a point where the retail price would be absurd to the average professional.
Market volatility and the ‘B&H Effect’
The numbers coming from the retail market illustrate this collapse. In February 2025, the 2TB version of the Rugged SSD Pro5 was positioned at $400, with the 4TB model at $600. Today, that 2TB model has vanished from stock, listed as discontinued. Meanwhile, the 4TB version is currently listed at B&H for approximately $1,600—a staggering 167% price increase in under two years.
This pricing volatility suggests that remaining stock is being treated as a speculative asset rather than a consumer electronic. For the creative professional, this creates a precarious environment. The tools required for high-bitrate 8K video editing are becoming prohibitively expensive not because of a lack of innovation, but because the underlying raw materials are being redirected toward the cloud.
The broader trajectory
The discontinuation of the SSD4 and Pro5 serves as a canary in the coal mine for the rest of the hardware industry. As long as AI infrastructure remains the primary driver of silicon demand, ‘prosumer’ hardware will continue to feel the squeeze. We are entering an era where the most capable hardware may not be defined by what engineers can build, but by what manufacturers can actually afford to source in a market dominated by hyperscale data centers.
