IBM Ultrastar 73LZX 73.4 GB ... read/write channels, a feed-forward servo control that improves seek and settle time, and better suspension dynamics that enable greater servo bandwidth, faster speeds, and improved mechanical stability. To achieve maximum I/O performance, the drives combine fast seek times, large 4 MB multi-segmented buffers, a sophisticated command queuing system, hardware automation, and industry-leading internal data rates. They also employ fifth-generation giant magnetoresistive (GMR) head technology to double areal density and performance. In addition, highly efficient No-ID sector formatting enables more data to be stored per disk.

To help ensure data protection, IBM Ultrastar drives include IBM-exclusive reporting tools, such as Predictive Failure Analysis (to signal potential drive problems) and Drive-TIP (to monitor drives and avoid malfunctions). Load/unload technology and glass substrate disks also increase reliability by providing a more robust solution at high rotational speeds. IBM Ultrastar drives provide extremely quiet operation. In addition, tri-laminate drive covers reduce both idle and seek acoustics while an improved spindle motor driver enables smoother commutation.
