Frequently Asked Questions

What is the difference between 03KH159 and 4XB7A82366?

Both are Lenovo 1.92TB PCIe 5.0 x4 NVMe Read Intensive 3D NAND TLC SSDs with tray for the SR860 V3 — alternate part numbers that may differ in NAND manufacturer or firmware revision. Verify from Lenovo's compatibility matrix.

What is PCIe 5.0 vs PCIe 4.0?

PCIe 5.0 doubles the per-lane bandwidth of PCIe 4.0 — from 2 GB/s to 4 GB/s per lane. For x4 NVMe SSDs, this means up to 16 GB/s theoretical bandwidth vs 8 GB/s for PCIe 4.0.

Is this compatible with non-Lenovo servers?

This is an OEM Lenovo ThinkSystem SSD validated for the SR860 V3. Compatibility with non-Lenovo servers is not guaranteed.

The Lenovo 03KH159 delivers 1.92TB of PCIe 5.0 x4 NVMe Read Intensive 3D NAND TLC SSD storage with tray — validated for the Lenovo ThinkSystem SR860 V3 for next-generation NVMe enterprise deployments.
