About the 4XB7A13914

The Lenovo 4XB7A13914 is an 18TB 3.5-inch hot-swap SAS 12Gb/s enterprise hard drive built on a helium-sealed 7,200 RPM mechanical architecture. Sourced from tier-one manufacturers including Seagate (Exos X18) and Western Digital (Ultrastar DC HC550), it is engineered for bulk storage arrays, object storage pools, video surveillance archives, and long-term backup repositories in ThinkSystem servers.

Compatibility

Compatible with Lenovo ThinkSystem SR650, SR650 V2, SR650 V3, SR665 V3, and ST650 V2 servers configured with 3.5-inch drive backplanes. It connects through 12Gb SAS controllers or HBAs (such as the RAID 930/940 or 430/440 series). It requires SAS-compatible backplanes and cannot be attached to SATA-only controllers.

How to identify a genuine unit

The drive tray displays a Lenovo 18TB SAS 12Gb 7.2K label. The drive casing displays Lenovo option part number 4XB7A13914, FRU part number 02DA207, and feature code BKYY alongside the OEM model number ST18000NM003J. The drive reports genuine Lenovo firmware via SCSI inquiries.

Buying used

When buying used 18TB enterprise hard drives, request SMART and SCSI error logs verifying zero grown defects, reallocated sectors, or read/write verification errors. Check helium integrity metrics to confirm the internal seal remains pressurized. Verify that the drive is mounted in an authentic Lenovo 3.5-inch hot-swap tray.
