SK hynix Unveils PEB110 E1.S Gen5 PCIe Up to 8TB SSD for Data Centers

SK hynix Inc. announced that it has developed PEB110 E1.S, a high-performance SSD for data centers.

With the advent of the AI era, customer demand for high-performance NAND solutions such as SSDs for data centers, as well as ultra-fast DRAM chips including HBM, is growing. In line with this trend, the company has developed and introduced a new product with improved data processing speed and power efficiency by applying the Gen5 PCIe ⁽¹⁾ specs.

The company expects to meet diverse customer needs with a more robust SSD portfolio following successful mass production of PS1010 ⁽²⁾ with the introduction of PEB110.

The firm is currently in the qualification process with a global data center customer and plans to begin mass production of the product in 2Q25, pending qualification.

PCle Gen5, applied to this product, provides 2x the bandwidth of the Gen4, enabling PEB110 to achieve data transfer rates of up to 32GT/s. This enables PEB110 to double the performance of the previous-gen and improve power efficiency by more than 30%.

SK hynix has also applied the security protocol and data model technology, or SPDM, to PEB110, for the 1st time for its data-center SSDs to significantly enhance information security features.

SPDM, a key security solution specialized in protecting server systems, offers secure authentication and monitoring of servers. With the recent increase in cyberattacks on data centers, the company expects that PEB110 with SPDM will meet the high information security needs of customers.

The product will be released in 3 capacity versions – 2, 4, and 8TB – and supports the OCP ⁽³⁾ version 2.5 specs for greater compatibility across global data centers.

“The new product builds on the company’s best-in-class 238-high 4D NAND, boasting the most competitive standards in the industry in terms of cost, performance and quality,” said Ahn Hyun, head, N-S Committee. “Looking ahead, we are on track to proceed with customer qualification and volume production to solidify our position as the No. 1 global AI memory provider in the ever-growing SSD market for data centers,” said Ahn.
