The PM9E1, a new PCIe 5.0 SSD that is said to be the highest performing and largest capacity of its kind in the industry, built on Samsung’s in-house 5-nanometer-based controller and eighth-generation V-NAND (V8) technology, is now in mass production, Samsung Electronics has announced. This SSD is said to deliver sequential read/write speeds of up to 14.5 GB/s and 13 GB/s, figures that amount to more than a 2x improvement versus previous-generation products, according to Samsung.
Samsung writes:
- “Key attributes in SSDs, including performance, storage capacity, power efficiency and security, have all been improved compared to 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 up to 14.5 gigabytes-per-second (GB/s) and 13GB/s, respectively.”
- “This powerful performance enables faster data transfer even with data-intensive AI applications, allowing a 14GB large language model (LLM) to be transferred from the SSD to DRAM in less than a second.”
- “The PM9E1 offers a range of storage options, including 512GB, 1 terabyte (TB), 2TB and the industry’s largest capacity of 4TB.”
- “Additionally, the significantly improved power efficiency of over 50% allows for longer battery life which is ideal for on-device AI applications.”

Samsung added:
For stronger security measures, Samsung has applied Security Protocol and Data Model (SPDM) v1.2 to the PM9E1. The SPDM specification provides ‘Secure Channel,’ ‘Device Authentication’ and ‘Firmware Tampering Attestation’ technologies that can help prevent supply chain attacks involving forgery or manipulation of stored data in the product during production or distribution processes.
Starting with PM9E1, Samsung plans to expand its advanced SSD offerings to global PC makers and expects to launch PCIe 5.0-based consumer products in the future to solidify its leadership in the on-device AI market.
