Frequently Asked Questions

What is E1.S form factor?

E1.S is a compact NVMe SSD form factor defined by the EDSFF (Enterprise and Data Center SSD Form Factor) standard. It enables higher storage density than 2.5-inch U.2/U.3 SSDs in compatible server platforms designed for E1.S bays.

What is the difference between 4XB7A95052 (E1.S) and 4XB7A95053 (U.3)?

Both are Lenovo ThinkSystem Read Intensive NVMe SSDs with SED/TCG Opal encryption. The 4XB7A95052 uses E1.S form factor (7.68TB) while 4XB7A95053 uses U.3 form factor (15.36TB). Choose based on your server's supported NVMe form factor.

What is TCG Opal 2.0?

TCG Opal 2.0 is an industry-standard specification for Self-Encrypting Drives enabling hardware-based full-disk encryption managed by compatible software, meeting compliance requirements for data-at-rest encryption.

The Lenovo ThinkSystem 4XB7A95052 delivers 7.68TB of PCIe 4.0 x4 NVMe Read Intensive 3D NAND TLC SSD storage in an E1.S form factor with TCG Opal 2.0 encryption — purpose-built for high-density secure NVMe storage in Lenovo ThinkSystem enterprise deployments.
