Buying used
When purchasing used 10K SAS hard drives, request SCSI defect lists and SMART logs to ensure zero grown defects or reallocated sectors. Check power-on hours and listen for abnormal spindle motor bearing noise. Verify that the drive includes the authentic Lenovo 2.5-inch hot-swap caddy with functioning latch.
