Samsung’s new SSD promises fast data transfer

Samsung Electronics has announced the mass production of its PM9E1, a PCIe 5.0 SSD that boasts the highest performance and largest capacity in the industry. Built on a 5nm controller and eighth-generation V-NAND technology, the PM9E1 offers enhanced power efficiency and powerful performance, making it an ideal choice for on-device AI PCs. Compared to its predecessor, the PM9A1, key attributes like speed, storage capacity, and security have all seen significant improvements.

The new SSD features an eight-channel PCIe 5.0 interface, enabling sequential read speeds of up to 14.5 gigabytes per second (GB/s) and write speeds of 13GB/s, more than doubling the capabilities of the previous generation. This impressive performance facilitates rapid data transfer for demanding AI applications, allowing large models to be transferred from the SSD to DRAM in less than a second.

Available in multiple storage options—512GB, 1 terabyte (TB), 2TB, and a market-leading 4TB—the PM9E1 is particularly suited for users needing high-capacity storage for large files, including AI-generated content and high-resolution videos. Its improved power efficiency, exceeding 50%, also supports longer battery life for on-device applications.

To enhance security, Samsung has implemented Security Protocol and Data Model (SPDM) v1.2, which includes features like secure channels and device authentication to prevent data manipulation during production or distribution. With the PM9E1, Samsung aims to expand its advanced SSD offerings to global PC manufacturers and plans to introduce additional PCIe 5.0-based consumer products to strengthen its position in the on-device AI market.
