Samsung Electronics Co., Ltd. announced the start of mass production of PM9E1, a higher performance and larger capacity PCle 5.0 SSD. Based on its internal 5 nanometer (nm) controller and eighth generation V-NAND (V8) technology, the PM9E1 will deliver powerful performance and improved power efficiency, making it an optimal solution for intelligence PCs artificial on-board. The key attributes of SSDs, including performance, storage capacity, energy efficiency and security, have all been improved over its predecessor (PM9A1a).
Thanks to the eight-channel PCIe 5.0 interface, the sequential read and write speeds of the new SSD have more than doubled compared to the previous generation, reaching 14.5 gigabytes per second (GB/s) and 13 GB respectively /s. This powerful performance enables faster data transfer even with data-intensive AI applications, allowing a 14GB Large Language Model (LLM) to be transferred from SSD to DRAM in less than a second . The PM9E1 offers a range of storage options, including 512 GB, 1 terabyte (TB), 2 TB, and the industry’s largest capacity, 4 TB.
In particular, the 4TB option is an optimal solution for PC users who need large storage capacity for large files such as AI-generated content, data-intensive programs and high-resolution videos. resolution, as well as for workload-intensive tasks such as gaming. Additionally, the significantly improved power efficiency of over 50% allows for greater battery life, which is ideal for on-device AI applications. To strengthen security measures, Samsung has applied Security Protocol and Data Model (SPDM) v1.2 to PM9E1.
The SPDM specification provides “Secure Channel”, “Device Authentication” and “Firmware Tampering Attestation” technologies that can help prevent supply chain attacks.
which can help prevent supply chain attacks involving the tampering or manipulation of data stored in the product during production or distribution processes. Starting with the PM9E1, Samsung plans to expand its offering of advanced SSDs to PC manufacturers around the world and hopes to launch consumer products based on the PCIe 5.0 standard in the future to consolidate its leading position in the market of on-device AI.
