Abstract
In some embodiments, a mass storage system may include a mass storage device having a plurality of memory channels, and a controller coupled to the mass storage device, wherein the controller is configured to control access to the mass storage device. For example, the controller may include code to determine a first vertical redirect budget for a first memory channel of the plurality of memory channels, revector defects in the first memory channel vertically within the first memory channel until the first vertical redirect budget is exceeded, and revector defects in the first memory channel horizontally outside of the first memory channel within another memory channel of the plurality of memory channels after the first vertical redirect budget is exceeded. Other embodiments are disclosed and claimed.
