About the 4XB7A10248

The Lenovo 4XB7A10248 is a 1.8TB 2.5-inch 10,000 RPM enterprise SAS 12Gb/s hot-swap hard drive. Designed for transaction-intensive business applications, mail servers, and OLTP database storage, it combines high-density spindle rotational performance with advanced 512e sector emulation, delivering high capacity within standard 2.5-inch server drive bays.

Compatibility

Compatible with Lenovo ThinkSystem SR650, SR630, SR850, ST550, SR650 V2, and SR630 V2 servers equipped with 2.5-inch SAS backplanes. Operates across 12Gb SAS RAID adapters and host bus adapters. It cannot be used with SATA-only backplanes or controllers and requires a host OS supporting 512e formatting.

How to identify a genuine unit

The drive carrier displays a 1.8TB 10K SAS 12Gb label. The drive casing displays Lenovo option part number 4XB7A10248, FRU code 01GV616, and feature code B0YT alongside OEM model number ST1800MM0129. In XClarity Controller, it reports certified Lenovo firmware.

Buying used

When evaluating a pre-owned 1.8TB 10K SAS drive, inspect SMART logs to verify zero reallocated sectors and clean background scan statistics. Confirm that the drive operates without excessive vibration or bearing noise. Verify that the drive is mounted in an authentic Lenovo 2.5-inch hot-swap tray with intact screws.
