Sandisk, which has regained its independent structure, is preparing for a big leap in the world of data storage. The company announced its new generation SSD architecture called “Stargate”. The Stargate architecture, which is expected to reach 512 TB capacity by 2027, will offer SSD drives at the level of 1 Petabyte (1,000 Terabyte) in the long term.

Sandisk to develop 1 Petabyte SSD

The first products of the Stargate platform will be released to the market in 2024 with a capacity of 128 TB. It is planned to offer SSDs with a capacity of 256 TB in 2026 and 512 TB in 2027. These products will provide large-capacity solutions especially for large data processing centers, cloud service providers and artificial intelligence models.

The new architecture works with the PCIe Gen5 interface and is expected to be compatible with PCIe 6.0 in the future. Each QLC chip used in Stargate SSDs has a capacity of 2 TB and can be scaled up to 64 chips. This structure offers a significant performance increase compared to traditional 8-channel consumer SSDs.

The Stargate architecture will form the basis of Sandisk’s new enterprise SSD series called Ultra QLC. Significant improvements in performance are also achieved with the 64 TB and 128 TB models, which will be available in the third quarter of 2025.

Random read speeds increased by 68%, random writes by 55%, sequential reads by 7% and sequential writes by 27%. The new ASIC architecture and Stargate’s optimized controller design play a decisive role in this development.
