Frequently Asked Questions

What is the difference between 03KH965 and 4XB7A83764?

Both are Lenovo ThinkSystem 3.2TB PCIe 5.0 x4 NVMe Mixed Use SED SSDs — alternate part numbers that may differ in NAND manufacturer or specific server model validation. Verify from Lenovo's compatibility matrix.

What is Mixed Use vs Read Intensive?

Mixed Use SSDs are designed for workloads with higher write ratios (typically up to 50% writes) and carry higher write endurance ratings (DWPD). Read Intensive SSDs are optimized for predominantly read workloads and are more cost-effective for low write-ratio deployments.

Is this compatible with non-Lenovo servers?

This is an OEM Lenovo ThinkSystem SSD validated for ThinkSystem servers. Compatibility with non-Lenovo servers is not guaranteed.

The Lenovo ThinkSystem 03KH965 delivers 3.2TB of PCIe 5.0 x4 NVMe Mixed Use SED enterprise SSD storage — purpose-built for high-endurance, secure, next-generation NVMe workloads in Lenovo ThinkSystem server deployments.
