SanDisk has unveiled a new high-capacity solid-state drive that could revolutionize the scalability of data storage systems for artificial intelligence and cloud infrastructure. According to the brand, this solid-state drive is built on a new platform architecture designed to meet the growing performance and efficiency needs of hyperscale environments.
SanDisk NVMe solid state drive with 256 TB capacity sets a new standard for capacity
SanDisk has unveiled a 256 TB NVMe solid-state drive built on the new UltraQLC platform. This storage solution combines BiCS8 QLC NAND, specialized multi-core controllers, and advanced system-level tuning to deliver a new level of density and efficiency. The platform is designed to meet the growing demands of AI-driven tasks such as data collection, processing, and rapid analytics delivery in large-scale data lake environments.
The solid-state drive supports QLC direct write technology, which writes data directly to QLC NAND without relying on SLC caching, improving performance and power loss safety. The BiCS8 QLC matrix used in this solid state drive doubles the recording density per chip while maintaining a compact matrix size. SanDisk also introduced UltraQLC power optimization technology using dynamic frequency scaling, which is predicted to increase performance per watt by 10 percent.
Improved reliability includes a Data Retention profile, which is expected to reduce data rewriting frequency by 33%, increasing drive life and access stability. SanDisk has confirmed that the 256TB UltraQLC solid state drive and the 128TB SN670 variant will be available in the U.2 form factor in the first half of 2026. Other form factors are expected to be available later this year.
