This has now been demonstrated in a new NVMe enterprise-grade SSD by Sandisk and made possible by the company's enterprise-grade UltraQLC platform, which has further been made possible using a combination of BiC S8 QLC CBA NAND with custom controllers and advanced system optimisations.

Why Do You Need A 256TB NVMe SSD?

Sandisk says that in the AI era, flash storage must become more customisable to match complex workloads, and this is where this new SSD comes into play.

It has primarily been designed for AI-driven work, data-intensive workloads like data ingestion, preparation and more.

Key features of the Sandisk UltraQLC 256TB NVMe SSD:

1. It supports DirectWrite QLC, which the company claims eliminates SLC buffering.
2. BiC S8 2TB QLC die allows for double storage density while still maintaining a compact size.
3. There is also power optimisation at play, which allows for dynamic frequency scaling.
4. There is a scalable multi-core controller built in, which is responsible for maintaining high throughput and endurance at extreme capacities.
5. Sandisk claims there is a data retention profile, which reduces DR recycles by up to 33%.
