Hard Drives White Papers
Seeing the Future
Overview One of the greatest hindrances to hard disk performance is vibration. Like a needle on a record, the disk drive's head must try to follow narrow data tracks in order to read (or write) information. Physical disturbances can throw the head off-track and cause a delay while the actuator repositions it. This eventually has an impact on the hard drive's input/output performance. In modern, balanced hard drives, linear back-and-forth vibration barely affects the operation of the drive head. However, circular movements - rotational vibration - can cause serious disruption. These problems are particularly acute in multi-drive systems, because drives tend to be installed alongside each other, in arrays.
