Massive 8TB SD cards are set to ship 'shortly' after a two-year delay

After a two-year delay, SanDisk is set to launch 8TB SD cards that represent a major leap in storage capacity, conforming to the SDUC (Secure Digital Ultra Capacity) standard, which supports capacitie... Read original →

SanDisk’s 8TB SDUC card isn’t just a capacity milestone—it validates the trickle-down of 3nm NAND and EUV manufacturing into consumer storage. Technically, it pressures controller vendors to fast-track SD 7.0 adoption and reshapes the microSD Express ecosystem, offering NVIDIA’s Jetson platforms a new edge-AI storage pathway. From a compliance angle, ultra-high-density storage faces heightened export controls, especially when relying on TSMC in Taiwan, China, forcing SanDisk to reassess supply chain exposure. Samsung will likely counter not with bigger cards but by pushing UFS 4.0 with V9 speed class—shifting competition from removable to embedded storage. Over the next 12–24 months, these cards will remain niche in pro video and industrial IoT, but their strategic role lies in enabling offline large-model deployment as cloud inference costs surge.
