The Samsung PM9E1 Gen5 SSD delivers extremely fast data transfer, reaching up to 14.5 GB/s in sequential reads and up to 13 GB/s in sequential writes.
Samsung has kicked off mass production of the PM9E1 Gen5 SSD for mainstream AI PC platforms, offering a first look at "consumer" performance from the Gen5 generation.
The company has begun mass-producing the fastest Gen5 SSD it has ever made. The announcement was posted on the company blog and lays out the features and specifications of the PM9E1 Gen5, which is expected to be the highest-performing storage drive in the industry.

The Samsung PM9E1 Gen5 SSD is built with an in-house 5nm controller and eighth-generation V-NAND (V8) technology, which gives the drive high storage capacity and solid reliability. The SSD also reaches extremely fast sequential read and write speeds of 14.5 GB/s and 13 GB/s, respectively.
An Executive Vice President of Memory Product Planning at Samsung Electronics said,
The Samsung PM9E1 Gen5 is built around a 5nm controller, delivering industry-leading power efficiency and optimal performance that has been validated by key partners. In the fast-growing era of on-device AI, Samsung's PM9E1 will give global customers a solid foundation for effectively planning their AI portfolios.
Starting with the PM9E1, Samsung plans to extend its advanced SSD lineup to PC makers worldwide, and it expects to launch consumer products based on PCIe 5.0 in the future to strengthen its leadership in the on-device AI market.
Samsung says the PM9E1 Gen5 will deliver excellent performance and improved power efficiency, making it an ideal choice for AI PCs. Beyond performance and energy savings, the PM9E1 also offers better security than its predecessor, the PM9A1a SSD. It integrates the Security Protocol and Data Model (SPDM) v1.2, providing technologies such as a secure channel, device authentication, and firmware integrity attestation to prevent spoofing and tampering attacks.

Through the Gen5 interface, the Samsung PM9E1 SSD can reach sequential read/write speeds twice as fast as previous versions, making it a powerful solution for data-hungry AI applications. That lets it move 14GB of a Large Language Model into DRAM in under a second. It also extends battery life on devices such as laptops, with power efficiency that is 50% higher.
The PM9E1 Gen5 will be available in several capacities, including 512 GB, 1 TB, 2 TB, and 4 TB. Typical users will find the 512 GB and 1 TB capacities sufficient, while content creators and enthusiasts can store large amounts of data such as high-resolution video, games, apps, and AI-generated content on the 2 TB and 4 TB drives.
The official market release date for this product has not been announced, and Samsung has not announced pricing for the different capacities of the PM9E1 Gen5. Samsung has also confirmed that it plans to extend its Gen5 SSD lineup to PC makers worldwide and expects to launch more consumer-oriented PCIe 5.0 products soon. So anyone waiting for Gen5 PRO and EVO SSDs should expect an announcement before long.
