About the 4XB7A17128
4XB7A17128 is Lenovo's entry-tier 480GB read-intensive SATA 6Gb/s 2.5-inch hot-swap solid state drive built on Intel/Solidigm D3-S4520 flash architecture. Designed as an economical boot and local utility drive, it delivers consistent read throughput of 550 MB/s and up to 88,000 read IOPS. It sits at the entry capacity point of Lenovo's ThinkSystem SSD catalog, replacing the older S4510 generation. It is commonly configured in RAID-1 mirror pairs to host VMware ESXi, Windows Server, or Linux operating system installations.
Compatibility
The drive fits 2.5-inch hot-swap drive backplanes on ThinkSystem SR650, SR650 V2, SR630, SR630 V2, SR530, and related rack and tower servers. It interfaces with any SAS/SATA controller or onboard SATA AHCI port. It cannot be installed in legacy ThinkServer Gen5 caddies or HPE ProLiant carriers. Because it is a 2.5-inch form factor, it will not fit 3.5-inch server bays without a dedicated 3.5-inch bracket adapter.
How to identify a genuine unit
A genuine Lenovo unit includes a ThinkSystem drive tray bearing a label with option code 4XB7A17128, FRU number 02CW112 or SP47A17128, and feature code BA6J. The internal drive casing reveals Intel/Solidigm D3-S4520 markings and model SSDSC2KB480GZ. In UEFI and XCC storage management, the drive appears with Lenovo firmware (typically LDxx) and reports genuine status.
Buying used
Check the SSD wear gauge in smartctl (attribute 233 / Media Wearout Indicator). Boot drives typically sustain low write wear, making lightly used pulls a safe and cost-effective purchase. Ensure the SATA signal and power connector blades are free of cracking or physical strain from improper backplane insertion. Confirm the drive sled includes the necessary four mounting screws.
